Every home has those mysterious corners where… The Wi-Fi signal disappears. It can be annoying, especially if dead spots are located in areas where you need to connect frequently. Fortunately, while Wi-Fi dead spots are common, they are usually fixable.

“[Dead spots]are usually caused by distance from a Wi-Fi router, obstructions from walls and furniture, interference from other electronic devices, poor placement of the router or a combination of all of these factors,” smart home and networking writer Dhruv Bhutani explained to CNET.

Modern CNET poll revealed that 63% of US adults have seen their monthly internet costs increase, and we want to make sure you’re getting the most for your money. In a Recent Reddit thread Regarding Wi-Fi dead spots, many users cited frustration with frequent connection issues despite paying a lot of money for their internet. While some said mesh systems are the perfect solution, others pointed out that even expensive routers can’t overcome structural barriers like concrete walls or metal ductwork.

However, there are other ways to fix your Wi-Fi dead spots, and we’ve put together this guide to help you accurately diagnose and eliminate Wi-Fi dead spots for stronger, more reliable internet throughout your entire home.

How to find Wi-Fi dead spots

There are several ways to identify dead spots in your home and find out how widespread the problem is.

Run a speed test: CNET’s chief broadband correspondent Joe Subban “The best way to diagnose a dead zone is to do an examination,” he said Speed ​​testAfter this test, you will have access to “key information such as download and upload speeds, jitter, and response time.” “You can just drag your phone into the (potential) dead zone and run a speed test from there.”

You will need to walk around your home and perform tests in the most important areas. If the speeds don’t match the rest of the house or are significantly lower than the internet plan you’re paying for, you may have hit a dead spot.

Supan recommends Ookla but points out several other solid options, including Fast and M-Lab. (Disclosure: Ookla is owned by the same parent company as CNET, Ziff Davis.)

Mapping your networkFor deeper analysis, you can map your network using the Wi-Fi Analyzer app on your phone. Bhutani recommended starting with Netspot and Fing; Both are great options and are available for Android and iOS. Once you choose your app, go through your home to check your connection. In the app, you should look for the section that shows the signal strength. This may be called “RSSI or Received Signal Strength Indicator,” he noted. These values ​​are measured in dBm, and the closer to zero, the better.

“If the indicator shows a signal strength of -30, that will be a fairly strong Wi-Fi signal, while a signal strength of -70 to -80 will be a weak signal,” he said. “Any less, and the signal will likely be unusable.”

Start with the easiest fixes

Now that you’ve identified your Wi-Fi dead spots, you may be wondering what’s causing them. Physical barriers play an important role here. The more walls, especially thick walls, between your Wi-Fi router and receivers, the lower the signal. Large furniture, metal appliances, other Wi-Fi equipment, and even aquariums can also absorb, block, or interfere with Wi-Fi signals.

Other culprits may include:

location: The placement of your router is another important thing to consider. Placing your router under a shelf on your TV stand may be tidy and aesthetically pleasing, but it may cause your Wi-Fi to drop. To fix this, “you should place your router in a central location in the home, away from the walls and a few feet off the floor,” Subban instructed. Some Wi-Fi routers also offer ceiling mounting options, which is better for full coverage, but is not required.

Adjust antennas: If your router has adjustable antennas, you should adjust them and determine if there is any improvement. It is recommended to point your antennas in different directions (one vertical and one horizontal) to ensure optimal signal for all devices, especially in multi-level homes.

Reboot: It is often one of the first solutions suggested by technical support agents. Rebooting your router is a simple but effective troubleshooting step. Like any computer or phone, a router can benefit from an occasional reboot to clear its cache, resolve glitches, and restart its operations. You can restart your router by unplugging it, waiting 30 seconds, then plugging it back in.

Drivers are the interface between the radio and the operating system and can become confusing. It’s simple, but a reboot can solve nearly 90% of problems, said Dave Coleman, director of wireless networking in the CTO’s office at Extreme Networks. CNET in a previous interview.

Reset to factory settings: If restarting doesn’t solve your problem, you can try Reset the router to factory settings. This can be done by logging into your router via its app or website using your credentials. You can also complete the task by inserting a paper clip into the reset slot on the back of the router, holding it for 30 seconds and waiting for the lights to turn off and back on. This may take a minute or two to complete.

Consider upgrading your equipment

If you’ve tried the steps above and nothing improves your Wi-Fi connection, Upgrade your gear That’s the next step to consider. “It’s always a Wi-Fi router. No matter how fast your Internet connection is, a bad Wi-Fi router will always limit its performance,” Subban said. The above solutions are quick and effective, but purchasing new Wi-Fi equipment can provide a more sustainable solution.

Upgrade your router: As technology advances, it is recommended that you upgrade your wireless router every five years. However, if you use a lot of devices on your router, such as Smart home equipment And many other devices, you may need to upgrade frequently.

One of the biggest benefits of upgrading your router is access to the 6GHz band Wi-Fi 6E and Wi-Fi 7 Routers.

“It’s a much less crowded band, which means you won’t get as much interference as you do with the 2.4 and 5 GHz bands used with Wi-Fi 6 routers,” Subban explained. It’s worth noting that only newer devices are designed to take advantage of 6GHz, so you’ll need to make sure your devices are compatible before purchasing.

Wi-Fi extenders vs mesh networks: To improve your Wi-Fi connection by removing dead spots, Wi-Fi extenders and mesh networks They are two of the most popular solutions. Both options are great and will likely improve your setup, but which one is best for you will depend on several factors.

A wifi extender It is a budget-friendly option and ideal for small spaces. The extender works by connecting to your Wi-Fi router and then “stretch” the signal throughout the space. The Linksys RE7310 is our current pick for best overall Wi-Fi extender and would be a solid addition to most spaces. This model will manage you About $80 But for a more affordable option, the TP-Link RE220 also made our list and it does Less than $15. If your home has multiple levels or you just need to cover a larger area, a mesh network may be the solution.

“Even the best Wi-Fi routers will have trouble penetrating walls or floors. If you’ve followed all the troubleshooting steps and you still have dead zones, my advice is to upgrade to a router Grid system“These use multiple routers to spread your Wi-Fi connection evenly throughout your home and you can get a sturdy three-piece system for less than $200,” Subban said.

During testing, our in-house experts loved it Aero 6 Plus Three-piece mesh WiFi system. It covers an area of ​​up to 4,500 square feet and connects more than 75 devices.

Configure your network

At this point, you should be up and running again and free of dead Wi-Fi hotspots. Tech experts can opt for a little fine-tuning to ensure your connection stays strong.

Switch channels: As we mentioned above, Wi-Fi works on different channels. If you live in an apartment building or have neighbors nearby, and several people are using the same Wi-Fi channel at once, this can slow down everyone. In this case, switching channels may be a good idea. You can use a network analyzer app to find an open channel and switch your router to it manually.

“Most newer routers come with a feature called ‘bandwidth routing’ that automatically connects your device to the ideal channel,” Subban added. “The 2.4GHz band has better range but slower speeds, while the 5GHz band is faster with a more limited range. You can connect your devices accordingly if you have two separate networks.”

Firmware updates: Whether you upgrade your router, it is always a good idea to update your router’s firmware. This ensures your device is running its best and has the latest security patches and performance improvements.
