What is wireless “dead zone”? This is how you find them to fix and repair

We take Wi-Fi for granted, but it’s not magic – it’s made up of radio waves that can be blocked and interfered with by solid objects. Fortunately, there are ways to locate and dispose of dead areas so you can enjoy the Internet anywhere in your home.

Let’s explore why Wi-Fi dead zones exist and how they are resolved.

What is the Wi-Fi dead zone?

A dead zone is simply an area in your house, apartment, office, or other area that is assumed to cover Wi-Fi, however, when you try to connect, the device does not register a signal.

If you move the device to a dead zone, Wi-Fi will stop working and you will not receive a signal. For example, if you walk into a room with a phone or tablet and the room is in a dead zone, you will no longer receive a Wi-Fi signal.

What causes Wi-Fi dead areas in the house?

Anything that interferes with Wi-Fi radio waves produces a dead zone. If you have a large house or office and you have a wireless router in one corner of the building, there may be a dead area in the opposite corner of the building that the Wi-Fi signal cannot reach.

Most of the houses were built before the development of Wi-Fi, so the floor plan and building materials may interfere with the Wi-Fi connection. Old houses may have thick plaster walls with a wire for wire support, and this metal wire can block Wi-Fi signals. Large metal objects, such as filing cabinets or metal walls, can also block a Wi-Fi connection.

Other devices may also interfere with the connection. Old cordless phones create Wi-Fi hotspots during use, and the microwave blocks Wi-Fi signals while driving. Baby monitors, wireless safety systems, and wireless audio systems have also been known to cause Wi-Fi problems.

If you live in an area with a high density of other wireless transmissions, interference may also damage Wi-Fi coverage. For example, if you lived in an apartment building where each unit has its own wireless router, the signals might “fight”.

Similarly, if your nearest Wi-Fi networks are configured for the same wireless channel as yours, this can cause interference, which reduces the signal strength of the network. This can lead to dead areas around the home.

How to detect wireless dead zones

An InSSIDer application that displays Wi-Fi signal strengths

You do not need special software to identify dead areas. Just grab your smartphone or other wireless device, connect to your wireless network, and walk away.

Pay attention to the Wi-Fi signal indicator on your smartphone. If the signal strength drops to zero, you have found a dead zone.

Even if the Wi-Fi signal only drops to a very low level, be sure to consider it. Unreliable signal strengths may result in slower speeds or prevent devices from switching on completely.

Keep in mind that the Wi-Fi indicator doesn’t update right away, so don’t spray while holding the phone. Walk slowly and take a break in areas where you might think of a Wi-Fi connection.

Of course, you can also use the software to detect wireless dead zones. On Android, the free Wifi Analyzer app shows you more detailed information about Wi-Fi signal strength.

Open the app, select the Signal Meter screen, and select a Wi-Fi network. Walk with the app open and you will see the signal strength change as you move from place to place.

Apple doesn’t allow third-party apps to use this information on iOS, so iPhone, iPad, and iPod touch users can’t use the app for more detailed information — they need to pay attention to the device’s regular Wi-Fi network. indicator.

If you have a Windows or macOS laptop, you can also measure the Wi-Fi signal strength with inSSIDer. Be careful when walking with your laptop and looking at its screen all the time.

How to Repair Wireless Dead Areas at Home |

Now that you’ve figured out exactly where your wireless dead zones are, you’ll probably want to remove them. Here are tips for improving Wi-Fi coverage.

Place the router in a better location

If the router is in one corner of your house, apartment, or office, there may be a dead area in the opposite corner of the building. Try moving the router to a more central location in the middle of your house, apartment, or office.

Adjust or replace the router antenna

Make sure the antenna of the wireless router is facing up and pointing vertically. If it points horizontally, you won’t get as much coverage. If your antenna is already at a full angle, try attaching a more powerful antenna to a wider transmission range.

Identify and set obstacles between you and the router

If your Wi-Fi router sits next to a metal filing cabinet, it will reduce the signal strength. As such, give it a try repositioning to achieve optimal signal strength

.

If there is a microwave, aquarium, or anything else that appears to be blocking the router signal and producing a dead zone, move the blockage (or router) and see if it removes the dead zone.

Switch to the least congested wireless channel

. When you find it, switch the router channel to reduce interference from other wireless networks.

Install the wireless repeater

If none of the above tips help, you can set up a wireless repeater to expand your coverage to a larger area. This can be necessary in large houses or offices.

You can even turn unused routers into a wireless repeater, which is one of many ways to reuse an old router

Use an Ethernet connection

You can also access the network using Ethernet cables. If your computer and router are close enough, connect the two using Ethernet and never worry about Wi-Fi signals ever dropping again.

Use a pair of power cord adapters

If you don’t want to see disappearing cables in the hallway, you can use power cord adapters instead. Connect one to the room with the dead zone and the other to the room with the router.

Driving your Wi-Fi strength still

Wi-Fi dead zones appear for a variety of reasons. This includes the location of the router, neighbors, the appearance of the walls of the building, the size of the coverage area, the electronic devices you have, and the furniture. A lot can cause problems, but trial and error can help you figure out the culprit.
