Headquartered near Chicago, CompTIA is a nonprofit trade association made up of more than 2,000 member organizations and 3,000 business partners. Although the organization focuses on educating and certifying IT professionals, CompTIA also figures prominently in philanthropy and public policy advocacy.

CompTIA certification program overview

CompTIA’s vendor-neutral certification program is one of the best recognized in the IT industry. Since CompTIA developed its A+ credential in 1993, it has issued more than two million certifications.

In early 2018, CompTIA introduced its CompTIA Infrastructure Career Pathway. While you’ll still see the same familiar certifications that form the bedrock of the CompTIA certification portfolio, this new career pathway program more closely aligns CompTIA certifications to the real-world skills that IT professionals need to ensure success when managing and supporting IT infrastructures.

CompTIA certifications are grouped by skill set. Currently, CompTIA certs fall info four areas: Core, Infrastructure, Cybersecurity and Additional Professional certifications.

• Core Certifications: Designed to build core foundational skills, CompTIA offers four Core certifications: IT Fundamentals+ (a pre-career certification focused on IT foundation framework), CompTIA A+ (focused on user support and device connectivity), CompTIA Network+ (targeting core system connections with endpoint devices), and CompTIA Security+ (focused on entry level cybersecurity skills).
• Infrastructure Certifications: Designed to complement the Network+ credential, you’ll find three Infrastructure certifications: CompTIA Server+ (focused on issues related to server support and administration), CompTIA Cloud+ (covering hybrid cloud, virtual system administration and deploying network storage resources), and CompTIA Linux+ (focused on Linux operating system administration and management).
• Cybersecurity Certifications: CompTIA offers three cybersecurity credentials: CompTIA CySA+ (CySA stands for Cyber Security Analyst, and targets IT security behavioral analysts), CASP+ (CompTIA Advanced Security Practitioner; focuses on professionals who design and implement security solutions), and the CompTIA PenTest+ (Penetration testing, targets professionals who conduct penetration and vulnerability testing).
• Additional Professional Certifications: This category includes several credentials which don’t readily fit into any of the foregoing CompTIA career paths, including: CompTIA Project+, CompTIA CTT+ and CompTIA Cloud Essentials.

CompTIA Core Certifications

CompTIA IT Fundamentals+

CompTIA IT Fundamentals+ is ideal for beginners with a basic understanding of PC functionality and compatibility as well as familiarity with technology topics, such as hardware basics, software installation, security risks and prevention, and basic networking. It’s also ideal as a career planning or development tool for individuals beginning their IT careers or those seeking to make a career change. A single test is required to earn the credential. CompTIA launched a new IT Fundamentals+ test (Exam FC0-U61) in September 2018. This new test focuses on computing basics, database use, software development and IT infrastructure. The English version of the prior test (Exam FC0-U510) retires on July 15, 2019. Exams in other languages retire on December 1, 2019.

CompTIA A+

The CompTIA A+ certification has been described as an “entry-level rite of passage for IT technicians,” and for a good reason. This certification is designed for folks seeking a career as a help desk, support, service center or networking technician. It covers PC and laptop hardware, software installation, and configuration of computer and mobile operating systems. A+ also tests a candidate’s understanding of basic networking, troubleshooting and security skills, which serve as a springboard for CompTIA networking or security certifications or those offered by other organizations.

According to CompTIA, more than one million IT professionals hold the A+ certification. The A+ is required for Dell, Intel and HP service technicians and is recognized by the U.S. Department of Defense. CompTIA released new “Core” exams for the CompTIA A+ credential on January 15, 2019. These new exams provide additional focus on operational procedure competency and baseline security topics. Candidates must pass the Core 1 (exam 220-1001) and Core 2 (Exam 220-1002) exams. The Core 1 test targets virtualization, cloud computing, mobile devices, hardware, networking technology and troubleshooting. The Core 2 exams focuses on installation and configuring operating systems, troubleshooting software, operational procedures and security.

CompTIA Network+

Many IT professionals start with the A+ certification. While the A+ credential is recommended, if you have the experience and don’t feel a need for the A+, you can move directly to the CompTIA Network+ certification. It’s geared toward professionals who have at least nine months of networking experience. A candidate must be familiar with networking technologies, media, topologies, security, installation and configuration, and troubleshooting of common wired and wireless network devices. The Network+ certification is recommended or required by Dell, HP and Intel, and is also an accepted entry-point certification for the Apple Consultants Network. The Network+ credential meets the ISO 17024 standard and just like the A+, it is recognized by the U.S. DoD. A single test is required to earn the certification.

CompTIA Security+

CompTIA Security+ covers network security concepts, threats and vulnerabilities, access control, identity management, cryptography, and much more. Although CompTIA does not impose any prerequisites, the organization recommends that cert candidates obtain the Network+ credential and have at least two years of IT administration experience with a security focus. To obtain the Security+ certification candidates must pass on exam, SY0-501.

Infrastructure Certifications

CompTIA Linux+

The CompTIA Linux+ Powered by LPI certification is aimed at Linux network administrators with at least 12 months of Linux administration experience. Such experience should include installation, package management, GNU and Unix commands, shells, scripting, security and more. The A+ and Network+ certifications are recommended as a preamble to this certification but are not mandatory. Candidates must pass two exams (LX0-103 and LX0-104) to earn this credential. The exams must be taken in order, and candidates must pass test LX0-103 before attempting LX0-104. In 2018, CompTIA began testing a new beta test (XK1-004). The beta test offering ended October 22, 2018. New exams generally follow beta test tests so interested candidates should check the Linux+ web page for updates.

CompTIA Cloud+

As the cloud computing market continues to grow by leaps and bounds, the CompTIA Cloud+ certification has been keeping pace. This certification targets IT professionals with two to three years of experience in storage, networking or data center administration. A single exam, CV0-002, is required. It tests candidates’ knowledge of cloud technologies, hybrid and multicloud solutions, cloud markets, and incorporating cloud-based technology solutions into system operations.

CompTIA Server+

CompTIA Server+ aims at server administrators with 18 to 24 months of experience with server hardware and software technologies, and the A+ certification is recommended. The Server+ credential is recommended or required by HP, Intel and Lenovo for their server technicians. It is also recognized by Microsoft and the U.S. Department of Defense (DoD). A single exam, SK0-004, is required to achieve this credential.

CompTIA Cybersecurity Certifications

CompTIA Cybersecurity Analyst (CySA+)

As cybercrime increases, the requirement for highly skilled information security analysts will continue to increase as well. The Bureau of Labor Statistics (BLS) reports anticipated growth of 28 percent for information security analysts between 2016 and 2026, the fastest rate of growth for all occupations. One of the newer additions to the CompTIA certification portfolio is the Cybersecurity Analyst (CySA+) certification. The CySA+ credential is specifically designed to meet the ever-growing need for experienced, qualified information security analysts.

CySA+ credential holders are well versed in the use of system threat-detection tools, as well as the use of data and behavioral analytics to secure applications and systems from risks, threats and other vulnerabilities. CySA+ certification holders are not only able to monitor network behavior, but analyze results and create solutions to better protect against advanced persistent threats (APTs), intrusions, malware and the like.

CompTIA describes CySA+ as a bridge cert between the Security+ credential (requiring two years’ experience) and the master-level Advanced Security Practitioner Certification (CASP), which requires 10 years of experience. To earn a CySA+, candidates must pass a performance-based exam.

CompTIA Advanced Security Practitioner+ (CASP+)

While CompTIA no longer uses the “master” designation, the highly sought-after CASP+ certification is most certainly a master-level credential. Targeting practitioners, CASP is the only performance-based, hands-on certification currently available from CompTIA. This certification is designed for seasoned IT security professionals who plan, design and implement security solutions in an enterprise environment.

Although this certification doesn’t impose any explicit prerequisites, it’s not a bad idea to earn the Network+ and Security+ certifications before tackling the CASP exam. You should also have 10 years of IT administration experience plus a minimum of five years of technical security experience (thus securing this certification’s place as a “master” credential).

Booz Allen Hamilton, Network Solutions and Verizon Connect, among other companies, require CASP+ certification for certain positions. The U.S. Army and U.S. Navy also accept CASP+ as an industry-based certification required by employees and contractors who perform IT work in DoD data centers. The CASP+ certification requires that candidates pass the CAS-003 exam, which consists of 90 multiple-choice and performance-based questions.

CompTIA PenTest+

The newest additional to the CompTIA certification family is the CompTIA PenTest+. An intermediate-level credential, PenTest+ is designed to complement the CySA+. While CySA+ is defensive in nature (focusing on threat detection and response), the PenTest+ credential is offensive, focusing on using penetration testing to identify and manage network vulnerabilities across multiple spectra.

There are no mandatory prerequisites, but the Network+ and Security+ (or equivalent skills) are highly recommended, along with a minimum of two years of information security experience. Candidates pursuing the cybersecurity career path may take the PenTest+ or CySA+ credential in any order.

The test was released in July 2018, and is focused on communicating and reporting results, analyzing data, conducting penetration testing and scanning, and planning assessments. The test also tests a candidate’s knowledge of legal and compliance requirements.

Additional Professional Certifications

CompTIA Project+

The CompTIA Project+ certification focuses exclusively on project management and is ideal for project managers who are familiar with project lifecycles from planning to completion, who can finish a project on time and under budget. Project managers interested in this certification should have at least one year of project management experience overseeing small- to medium-sized projects. The Project+ credential requires that candidates pass a multiple-choice exam, PK0-004.

CompTIA Cloud Essentials

The CompTIA Cloud Essentials certification is geared toward individuals who understand the business aspects of cloud computing and how to move from in-house to cloud storage. In addition, they should be familiar with the impacts, risks and consequences of implementing a cloud-based solution. A single test is required to earn the credential.

CompTIA CTT+

The CompTIA Certified Technical Trainer (CTT+) certification is perfect for anyone interested in technical training. It covers instructor skills, such as preparation, presentation, communication, facilitation and evaluation, in vendor-neutral fashion. Adobe, Cisco, Dell, IBM, Microsoft and Ricoh all recommend CTT+ to their trainers and accept it in lieu of their own in-house trainer certifications.

Two exams are required for the CTT+ credential: CompTIA CTT+ Essentials (TK0-201) and either CTT+ Classroom Performance Trainer (TK0-202) or CTT+ Virtual Classroom Trainer (TK0-203).

The CTT+ Classroom Performance Trainer and CTT+ Virtual Classroom Trainer are performance-based exams. In this case, you must submit a video or recording of your classroom (or virtual classroom sessions), and complete a form that documents your training preparation, delivery and student evaluations.

In addition to certification levels, CompTIA groups its certifications into several career paths:

• Information security
• Network and cloud technologies
• Hardware, services and infrastructure
• IT management and strategy
• Web and mobile
• Software development
• Training
• Office productivity

The CompTIA Certifications page lets you pick a certification level and/or a career path and then returns a list of certifications to focus on. For example, one of the most popular career paths in IT is network administration. CompTIA’s Network and Cloud Technologies career path offers numerous certifications that can help you advance your network administration career, such as IT Fundamentals+, A+ and Network+ (Core certs), along with Cloud+ and Linux+ (Infrastructure certifications) and Cloud Essentials.

Those interested in network security (one of the fastest growing fields in IT) should consider the certifications in CompTIA’s Information Security career path. This includes all four of the Core credentials (IT Fundamentals, A+, Network+ and Security+) along with all cybersecurity certifications (CySA+, PenTest+ and CASP+).

CompTIA provides a comprehensive IT certification roadmap that encompasses certifications from CompTIA as well as a variety of other organizations, including Cisco, EC-Council, Microsoft, (ISC)², ISACA, Mile2 and more.

Because CompTIA credentials do not focus on a single skill (such as networking or virtualization), CompTIA credential holders may find themselves in a variety of job roles depending on their experience, skill levels and areas of interest. Here are just a few of the possible careers that CompTIA credential holders may find themselves engaged in:

• A+: Typically, A+ credential holders find work in support roles, such as support administrators, support technicians or support specialists.
• Network+: Network+ professionals primarily work in network-related roles, such as network analysts, administrators or support specialists. Credential holders may also work as network engineers, field technicians or network help desk technicians.
• CySA+ Security Analyst: Common roles for professionals interested in cybersecurity, information security and risk analysis may engage in roles that include security engineers, cybersecurity analysts or specialists, threat or vulnerability analysts, or analysts for security operations centers (SOCs).
• Security+: Security spans a variety of jobs, such as network, system or security administrators, security managers, specialists or administrators, and security consultants.
• Server+: Roles for server professionals include storage and server administrators, as well as server support or IT/server technicians.
• Linux+: Linux professionals often work in roles such as Linux database administrators, network administrators or web administrators.
• Cloud+/Cloud Essentials: Cloud+ credential holders typically work as cloud specialists, developers or system and network administrators. Cloud Essentials professionals tend to work in areas related to cloud technical sales or business development.
• CASP+: Common roles for CASP+ credential holders include cybersecurity specialists, InfoSec specialists, information security professionals and security architects.
• Project+: Project+ credential holders typically engage in project leadership roles, such as project managers, coordinators and directors, or team leads.

While the examples above are by no means exhaustive, they provide an overview of some available careers. Your career choices are limited only by your interests, imagination and determination to achieve your personal goals.

Back to top

A typical examination question in Mathematics will have several parts to it. Some parts (most usually at the beginning of the question) test your knowledge, by asking you to reproduce "bookwork", i.e. material presented in the lectures. Really, these parts test how well you've revised. Occasionally, especially in certain more advanced courses, there are entire questions that are bookwork. In some courses, some pieces of bookwork come up in the test almost every year. In other courses, hardly any bookwork is set explicitly.

Tip: Figure out which pieces of bookwork come up most frequently, and make sure you can answer those questions easily and quickly.

You would be surprised how many poor attempts at routine bookwork questions we see every year. These are the parts of the questions that we expect students to be able to do.

Other parts of examination questions involve a "problem". In a "Methods" course, this will typically involve you applying a known technique from the course, and again this is something we expect you to be able to do. In a Pure Mathematics course, you might be asked to prove a result, or to apply a result in a particular setting.

Tip: Sometimes (but certainly not always!), the first part of the question is intended as a big hint as to how you should approach the second part.

Many test questions, especially those that are otherwise very routine, have a last part (a "rider") which is more challenging than the rest of the question. This is quite deliberate, and the intention is to test whether you've really understood the material.

Tip: Do try all the riders (they're not always so hard after all!) but don't waste too much time on them in an test if there are other things you can tackle instead.

Students sometimes seem to be annoyed that they have to do something clever to get 100% on a question. Don't forget, in many other subjects it's practically impossible to score 100% on a question!

Tip: Make sure you've answered all the parts of the question. Sometimes you're asked to do seven or eight things, and it's easy to overlook one.

Wi-Fi problems can strike anyone at any time, no matter how much networking experience you have. But if you’ve not come across a particular Wi-Fi issue before, there’s no harm in not knowing how to fix it. All you need are the right tools and a few tips, and you’ll be able to diagnose and solve your Wi-Fi problem in no time.

Whether you’re experiencing problems with slow internet, Wi-Fi signal dropping, or you just can’t connect to Wi-Fi at all, here are some of the quickest and easiest fixes you can try; as well as some advanced stuff for more troubling Wi-Fi problems.

Slow or no internet access in certain rooms

Wi-Fi is made up of radio waves, meaning your Wi-Fi router broadcasts in all directions from a central location. If your router is in a far corner of your house, then you’re covering a great deal of the outside world unnecessarily. If you can, move your router to a more centralized location. The closer you can put your router to the center of your coverage area, the better reception will be throughout your home.

If you have external antennas, you can try adjusting those, too. Alternating between fully vertical and fully horizontal positions can help it reach in multiple directions.

If you live in an apartment building, other routers might be interfering with yours. Free software, like NetSpot on Mac, Windows, and Android, or Wi-Fi Analyzer for Android, can show you every wireless network nearby and what channel they’re using. If your router overlaps with nearby networks in particular rooms, consider switching to a less congested channel. If you need help switching, here’s our guide on how to change your Wi-Fi channel.

If none of that helps, your home might be too much for one router to handle. Consider purchasing a wireless repeater or setting up an old router to serve as one to extend the range of your main router. Upgrading to a whole-home mesh wireless system can also help with dead spots in certain areas of your home. Either way, it might be time to go and buy a new router.

Slow internet everywhere

If your Wi-Fi speed is slow no matter where you are, try plugging a laptop into your router directly and test your internet speed using one of the best internet speed tests. If speeds are still down, the problem is likely with your internet connection, not your router. Try some of these ways to Excellerate speed and contact your ISP.

If that’s not the issue, it could be that your current wireless channel is overcrowded by your devices or by those of other nearby networks. Consider changing the channel on your router in your router settings, by accessing the admin settings.

If that doesn’t help, performing a factory reset on your router and setting it up again may help. On most routers, there’s a Reset button that you can hold down with a paperclip. Do so for 30 seconds, and the router should default to factory settings. Use our guide to setting up a wireless router to get everything properly configured, and see if that helps.

If none of that works and your internet is fine on a wired connection, your router might be dying. Consider buying a new one: Here are the best routers we’ve reviewed and why they’re great picks. If the router seems fine, then it might instead be your modem, which could suffer connectivity issues if it’s on its way out, too. If you’re looking to upgrade your modem as a fix, we also have a guide on some of the top modem-router combos. Upgrading to a Wi-Fi 6 or Wi-Fi 6E router can also help ease issues with congestion and support faster speeds, provided that your broadband plan is capable of these boosted speeds.

One device can’t connect to the Wi-Fi

Sometimes you run into a Wi-Fi issue with one particular device. It’s probably just a momentary network issue, which is an easy fix. Try turning off the Wi-Fi on your device, then re-enabling it — or unplugging and replugging your Wi-Fi dongle. If that doesn’t work, restart the device and try again. Then try restarting the router itself.

If that doesn’t help, or if the problem reoccurs, consider deleting your current network from the list of saved networks on your device, then reconnect again.

If you’re running Windows 10 or 11, search for “wifi troubleshooting” and open the result, which should be Identify and Repair Network Issues. That will go through a series of diagnostics that may restore connectivity. On MacOS, you can run Wireless Diagnostics. Hold the Options key and click the AirPort (Wi-Fi) icon on the menu bar. Find Open Wireless Diagnostics, and then follow the on-screen instructions.

Nothing can connect to Wi-Fi

If you can’t connect to your Wi-Fi at all, plug your laptop into the router directly using an Ethernet cable, and see if you can connect that way. The particular type of Ethernet cable doesn’t matter, but there are some Ethernet cables that are better than others. If that works, your Wi-Fi is the problem and you should try some of the other fixes listed here. If it doesn’t work, then your internet may be down altogether. Check your ISP’s webpage and social accounts, or supply them a call to see if they are reporting problems. Sometimes providers can be a little slow to note issues, so you can also check with a monitoring site like Downdetector and see if other users in your region are reporting problems.

Resetting your router can fix a myriad of issues, too, and an inability to connect is one of them. Press the Reset button on the back of the router with a paperclip for 30 seconds, and the router should default to factory settings. Use our guide to setting up a wireless router to get everything properly configured.

If that’s no use, you may need to consider buying a new router.

Connections drop at random times

Changing your router’s channel might help. You can use NetSpot on Mac and Windows and Wi-Fi Analyzer for Android to show you every wireless network nearby. If yours overlaps with nearby networks, switching to a less congested channel in your router settings can help. We have a guide that will walk you through changing the channel on your router.

You can also try moving your router to a more accessible location so that there’s less distance (and interfering devices) between you and the router.

If that doesn’t work, try performing a factory reset on your router by pressing a paperclip into the miniature hole on it and following the reset steps as outlined in your manual.

Wi-Fi network disappears entirely

If you lose track of your Wi-Fi network on any device, it’s possible that your router reset itself. Do you see an unprotected network named after your brand of router? That might be yours. Connect a laptop or desktop to it via an Ethernet cable, then use our guide to setting up a wireless router to get everything properly configured again.

If you don’t see such a network, plug your laptop into the router with an Ethernet cable, and see if you get a connection. Use our guide to finding your router’s IP address and login information for more help. Also, if you don’t have a cable, check out our guide on how to choose the right Ethernet cable.

The network connects, but there’s no internet access

It might sound like a tired tip, but try resetting your modem by unplugging it and plugging it back in. If that’s no good, you can connect a laptop or desktop to your router with an Ethernet cable (these are the best ones) to see if it’s the router or your Wi-Fi that’s not working. If this works, then your best bet to get Wi-Fi working again is to reset your router. If there’s still no internet, though, you may have an outage. Contact your ISP.

Router crashes regularly and only restarting it helps

If your router needs to be restarted regularly, consider giving it a full reset. On most routers, you’ll find a Reset button that you can hold down with a paperclip. Do so for 30 seconds, and the router should default from factory settings. Use our guide to setting up a wireless router to get everything properly configured.

If that doesn’t work, your router may be on its way out. Your only real option is to return it if it is within its warranty period or to buy a new one.

Wi-Fi connection lost when logging back into the computer

This problem can crop up on Windows 10 due to an issue with Fast Startup. Fast Startup keeps certain processes running so you can log back in very quickly. However, this can sometimes cause a bug with the wireless driver that prevents it from reconnecting to Wi-Fi properly. In the short term, you can turn off Fast Startup to prevent this problem. Search for Power Options in your Windows 10 or Windows 11 search bar and go to this section of the Control Panel. Select Choose What the Power Button Does on the left-side menu, and then look at the new section Shutdown Settings. Find the option to Turn On Fast Startup and make sure it is deselected.

In the long term, you may need to update the driver for your wireless network adapter to fix any bugs causing this issue. You can follow our guide on how to update Windows 10 drivers for more information.

Forgot the Wi-Fi password

If you really can’t remember your Wi-Fi password, and there are no notes or cards with it written down somewhere, you’ll have to reset your router. Use a paperclip to press the hidden switch in the pinhole on the back of your router for 30 seconds. It should then default to factory settings.

Use our guide to setting up a wireless router to get everything properly configured.

Unknown devices on my Wi-Fi network

Log into your Wi-Fi app or administrator settings (which you can find by searching your IP address on your browser). Look for a list of currently connected devices and pinpoint the ones you don’t recognize.

First, make sure these don’t represent connections you didn’t realize you had — each smart device will have its own connection, for example, and they can have some strange titles if you didn’t name them. Game consoles and TVs may also be connected, and if you’ve had friends and family over recently they may have connected with unfamiliar devices.

If you’ve ruled out all familiar devices and there’s still a connection or two you don’t recognize, it’s possible someone else is hijacking your Wi-Fi network. In this case, look in your settings for an option to block these devices on your Wi-Fi and ban their MAC addresses, if possible. Then change your Wi-Fi password, and reboot your router. This may not stop especially determined hackers, but it’s usually enough to kick unwanted guests off your network.

If you want to take more drastic action, here are some steps for how to deal with someone stealing your Wi-Fi.

A recent update broke Wi-Fi

This can happen with some operating system updates. Windows 10 updates in mid-2020 had bugs that stopped some users from connecting to their Wi-Fi networks or even seeing a Wi-Fi connection at all. Similar updates to iOS, Android, and other platforms also have created bugs in the past that disrupt Wi-Fi connections.

When something like this happens, it’s best to wait for a patch that fixes the problem. In the meantime, remove the update and roll back your system to an earlier version to help get your online connectivity back.

While routers can last for years without needing a replacement, keep in mind that some problems can develop with age — a router may start lacking support for new device updates and similar issues that prevent it from working properly (as seen when Apple discontinued the AirPort Extreme, for example). That’s a sign that it’s time to look for a new router.

The satellite routers on my mesh network aren’t connecting

Make sure that your satellite devices are powered up and turned on. If they are, try unplugging and replugging the problematic device and see if it will connect to your network then. If your router app allows you to restart a Wi-Fi point (Google’s Home app, for example, allows this), then reboot that point and see if this helps, too.

Google also allows you to run a test to make sure the network is set up properly. You can find Wifi points on the Home app, under Test mesh. If the test comes back with a weak or failed connection, you should try repositioning your satellite routers to be closer to your primary router. This also is a good tactic for any mesh system that keeps dropping its satellite points — they could be too far away from the primary point.

You can also double-check to make sure that your satellite router devices have a different SSID than your primary router. If they were accidentally all assigned the same SSID, then the mesh network may not be able to coordinate properly.

If your router still seems unable to connect, then make sure that nothing significant has changed for your network settings. For example, if your ISP WAN (wide-area network) type changed for some reason, you may have to go back into the settings for the router and make sure that the right WAN setting is chosen.

There are additional special cases where certain Wi-Fi technology can interfere with mesh networks, so it’s also a good idea to contact router support directly and explain your situation if nothing is working.

My smart device isn’t connecting to Wi-Fi

First, make sure that your smart device and your router are both updated. Then try resetting your router and rebooting your smart device. You can either unplug and plug in the smart device or check its app for a reboot option — the Google Home app, for example, has a Reboot tool under each device section that you can use.

If the device still isn’t connecting properly, try moving it next to the router and seeing if it connects then — distance and interference can make a difference, especially for smaller smart devices. You should also double-check to make sure that your smart device doesn’t need a Zigbee hub to operate, which is more common among older smart devices but a problem that still occasionally crops up.

If your smart device keeps dropping a Wi-Fi signal, especially during busy times of the day, check to see if your router supports automatic band switching for devices. If it does, try turning this feature off. Sometimes a router will try to switch a smart device to a different band, but the device isn’t ready for that, causing it to lose a connection. There may also be issues with connecting to a mesh router, and you may have to be very specific about your network connection to make smart devices work.

It’s also a good idea to check if your particular device is suffering from temporary bugs that make connecting to Wi-Fi difficult or impossible. Nest minis and HomePod minis have both encountered such errors in the past. In these cases, a fix is usually patched in before too long, so keep making sure that your device is updated. Sometimes operating system updates, like a new iOS patch, also can affect smart device performance.

There are a number of other router settings that may block smart devices, but they are manufacturer dependent. If you can’t find what’s wrong, contact your router manufacturer’s support and explain that you think your router is having trouble connecting.

My console can’t connect to Wi-Fi

Check social media and Downdetector to make sure nothing is wrong with your gaming platform — sometimes your Xbox or PlayStation can get online just fine, but Xbox Live or Playstation Network is down for any number of reasons, but they’re typically back up again after a short period.

If everything looks all right there, reboot both your router and your game console and see if they can successfully connect. This is also a good time to test your internet connection. Major systems like Xbox and PlayStation have an option in their Settings menu to test your internet connection. On PlayStation, head to Settings, then Network, then select Test Internet Connection. On Xbox, go to Profile & System, select Settings, and in the General section, select Network Settings, where you will find an option to Test Network Speed & Statistics. This can provide more information about what’s going wrong and even tips on what you may need to change.

If your console and router seem to be acting properly but Wi-Fi keeps dropping, you may want to try moving the two devices closer to each other to see if the Wi-Fi signal improves. Try to remove any material or objects between the console and router: Placing both in a high, clear location often brings the best results. You can also try reducing the number of other devices on the network, especially if they’re streaming.

Can’t connect to wireless printer

First, make sure you are trying to connect to your Wi-Fi and not via Wi-Fi Direct — they are two different technologies. We also highly suggest the traditional routine of turning everything off and back on again, especially if your printer has connected to Wi-Fi successfully in the past. If your printer is far away from your router and keeps running into Wi-Fi errors, try moving it to a closer position.

If it looks like your printer is connected to Wi-Fi but you can’t get it to work, head into your printer settings on your computer and make sure the correct default printer is selected. Microsoft also has some troubleshooters you can run to see if they pick up on anything obviously awry.

It’s also a good idea to check your router security, firewalls, and VPN security to see if any of them are identifying the printer as a strange device and refusing a wireless connection. You may need to disable certain firewalls or reconfigure security protocols to use your printer successfully. When all else fails, uninstall your printer drivers and reinstall the more recent versions to see if this makes a difference.

And if your printer isn’t wirelessly enabled, consider upgrading to one that is. We have some recommendations for top printers, laser printers, and multifunction printers that can be used wirelessly and connect to your home network.

Can’t connect to a guest Wi-Fi network that I set up

Guest Wi-Fi networks allow you to share your Wi-Fi with others in a secure way that helps prevent security issues. You’ve probably seen it on business routers, but it can be set up on home routers, too. If someone is having trouble connecting to the guest network but otherwise the Wi-Fi seems to be working, there are a few things you can try.

First, if you just set up your guest network, wait a few minutes. It may take a little time for the network to show up. If the guest network is visible, take a minute to head into your router app and check settings. Settings like Public Wi-Fi Active and Allow Guests to Access My Local Network should always be enabled. If it’s still not working, reset your router and try again.

Keep in mind, some guest networks have a stricter limit on how many devices can use them. If you have over a dozen people already on the guest network, others may not be able to log on.

Wi-Fi 6 or 6E isn’t working, even with a Wi-Fi 6 router

Wi-Fi 6 offers a host of improvements from older Wi-Fi standards, including improved performance, less latency, and better security. But if you don’t think you’re getting Wi-Fi 6 features from a router that supports it, something could be wrong with your setup.

Do you have any extenders on your network? If those aren’t compatible with Wi-Fi 6, you won’t be able to enjoy Wi-Fi 6 speed and features. If your device has picked up the signal from an extender, Wi-Fi 6 benefits may not be making the trip.

Additionally, most devices will need at least partial support for Wi-Fi 6 features to be able to use them. Devices that are several years old may not be compatible with any Wi-Fi 6 changes. That includes your phone and laptop, as well as smart devices that you might be using.

Even desktop computers may struggle with this. Internal Wi-Fi adapters may struggle to pick up on Wi-Fi 6 benefits when you switch to a new router, even if they are technically compatible. You should update your Wi-Fi drivers to fix any potential issues.

There has been some good news on climate change. Not enough. But good news nonetheless.

First of all, over the past decade or so, several major economies including the United States have shifted away from burning coal to generate electricity. Coal is the dirtiest of fossil fuels, and historically speaking a major contributor to greenhouse gas emissions.

There are still coal power plants being built in the world, but the overall trend away from coal toward cleaner options, like solar, is progress. The cost to build solar power plants has fallen enough that, in some cases, it is now one of the most price-competitive options for generating electricity. This is a significant financial milestone.

Cars that burn gas are a major contributor to planet-warming greenhouse emissions, but in the past few years some of the world’s largest automakers have launched aggressive efforts to pivot to making more electric vehicles while phasing out gasoline models. The importance of a significant polluting industry embracing this change, and competing with one another to be better at it, can’t be underestimated.

Car buyers have been responding. As recently as a half-decade or so ago, electric-car sales were negligible in many parts of the world, but have risen rapidly since. Electric vehicles aren’t perfect of course, but as a general rule they’re cleaner than gasoline cars. (If you’re interested in practicing more about that, try searching this F.A.Q. for “How green are electric cars?”)

The spread of electric vehicles also means that some of the difficulties of owning one (for example, finding charging stations nearby) will likely resolve themselves more quickly as demand grows from drivers. That, in turn, could encourage sales.

In 2022 the United States passed new legislation, the Inflation Reduction Act, that is widely considered the most important legislative effort to fight climate change in the nation’s history by encouraging a transition to cleaner energy and offering a range of incentives to businesses and individuals to clean up their act.

(This Times guide explains how you might be able to claim some of that money by, for instance, buying an electric car or installing a heat pump.)

Lastly, here’s a big one: For reasons like the above, in the past decade or so the world has made significant progress toward slowing global warming and avoiding particularly extreme consequences from climate change. Not nearly enough progress, mind you, but significant nonetheless.

Specifically, before the 2015 Paris Agreement, some estimates put the world on track to warm in the range of 3.6 degrees Celsius above preindustrial times. Scientists widely agree that if average global temperatures were to increase that much, it would be devastating socially and economically. Now, however, according to a United Nations report in 2022, the world is on track to heat between 2.1 degrees and 2.9 degrees by 2100.

That’s still very dangerous.

However, if the nations of the world act as aggressively as they promise, there remains a chance to hold that increase to below 2 degrees Celsius, according to scientists. That’s a big “if,” of course. It would require a tremendous amount of work by the nations of the world, on an extremely swift timetable over the next decade or two, to hit the lower targets for limiting global warming.

However, since you asked about good news, let’s keep it positive. Even if there’s a lot of hard work to do, progress has been made on important fronts.

There’s now even a movement, “OK Doomer,” that basically says, stop it with the gloomy takes and focus on things that will fix the problem.
