What Are Dead Zones and How to Fix Wi-Fi Signals There?

If you have WiFi at home, you might be plagued by something called “dead zones”. These dead zones are areas of low to no connectivity, where your WiFi simply cannot penetrate and provide working, stable internet.

The thing with WiFi signals is that like any other radio/electromagnetic wave, they can die out and even be halted by obstructions along the way. Dead zones are generally formed when your router simply cannot provide a stable internet connection throughout your house. It can be due to distance or because of obstructions.

Appliances like fridges, microwaves, televisions, and such that dispel a lot of EM waves counteract the signals from the router, dulling them down by a lot.

What is a Dead Zone?

A dead zone, or a dead WiFi zone is an area around a wireless LAN location where WiFi does not function. Similar to a house scenario, with a router in a room that provides connectivity to the entire house but cannot to some rooms or areas. This is due to radio interference or due to the sheer distance between source and receiver.

Since WiFi is a radio signal, anything that affects radio waves can affect WiFi signals. This includes, walls, metal sheets, other radio sources and electronics which are a source of electromagnetic interference.

How to avoid dead zones?

Dead zones can be carefully mitigated by setting up your home WiFi a little more carefully and considering where exactly to place the router and the sources of interference. Planning makes sure you will have no dead zones once you have set up your WiFi.

For better coverage,

Invest in a powerful router: If you are setting up your home WiFi, we suggest you invest in a powerful WiFi with a range of at least 20m-30m. A router with a good antenna can provide you seamless internet without having to change its position too much.
Position it centrally: Make sure you put the router in approximately the center of your house. This ensures the transmitted signals are sent in a 360-degree angle around the house and none of them are lost.
Make sure there are no strong electronics around: This is important, and you should be careful with the placement of the router. You should not place it around strong electronics or thick walls. Electronics tend to disrupt the signals from the router, and this causes dull signals throughout your house. Thick walls, floors and metal sheets also soak up a lot of these radio signals and can cause your connectivity to further slowdown.
Use WiFi boosters or extenders: You can alternatively use WiFi extenders like RangeXTD to boost WiFi signals around your house. WiFi extenders are devices that you can plug into a power socket, connect to your existing WiFi. Doing this, it becomes a beacon to your home WiFi and starts transmitting WiFi signals. This improves connectivity inside your house and is very efficient at dealing with dead zones.
Limit connections: If your connectivity still has not improved, you should try limiting the number of connections on the WiFi. This will not help with dead zones but does help with connectivity and speed.

Conclusion

These are the few things you can do to fix WiFi signals at home. The most functional fixes include getting a better router, positioning it well and using WiFi extenders. If there are still internet issues plaguing you, we suggest you have a chat with your internet service provider, or ISP, about the challenges and issues you are facing. They might have some input on it and can try and fix it for you.
