What Are The Reasons For Getting Poor Wi-Fi Signal?

Most people don’t know the reasons for weak Wi-Fi signals from their router. For that, below we have presented some common reasons for getting weak Wi-Fi signals.

What Are The Reasons For Getting Poor Wi-Fi Signal


Wireless routers use radio waves to transmit networking signals. How far the signal will travel usually depends on the router’s capacity. If your devices are far from the router signal coverage area, they could experience trouble connecting or degraded signal.


Wi-Fi signals can be interfered with by anything with a large electromagnetic field. This includes neighbor network systems, satellite service, LCD displays, and other networking systems. These devices usually interfere with the Wi-Fi networking signal to reach your device.


Physical obstacles, like the number of walls in your home or office also cause poor Wi-Fi signals. The more walls you have, the more interference the signal will face when traveling.

Besides, the type of doors and walls impact the Wi-Fi signals traveling through them. If you have thick doors or concrete walls, the signals won’t reach throughout all areas.


Router range capacity also plays a crucial role in getting the proper Wi-Fi signal in your area. Using a low-capacity wireless router in a larger room will get poor Wi-Fi signals outside the router’s coverage area.

For instance, A 2.4 GHz band wireless router will cover 150 feet indoors and up to 300 feet outdoors.

Dead Spots Or Zones

Dead spots are also causing your device not to get the proper Wi-Fi signals. These dead zones are usually created when your wireless router’s signals cannot reach the area. However, interference from thick walls, furniture, or metallic appliances can also create dead zones.

If your router is set up in a large home, the Wi-Fi signal may not reach all areas. Some areas may not have any signal, or some may have weak signals.

While installing the wireless router in a central location can help, some rooms may have problems with internet coverage. In such situations, installing a Wi-Fi extender or booster can solve the problem.

Outdoor Internet Access

Wi-Fi technology allows using the internet not only indoors but also outdoors. Sometimes you may like to browse the web or stream online in other places like the pool, garage, or porch.

Unfortunately, wireless routers are powerful enough to cover outdoor areas as well as indoors. In that case, a Wi-Fi booster can let you enjoy the internet in outdoor spaces.
