Why the WiFi has little signal but you are close to the router

What causes a bad WiFi signal

Normally you have a good wireless signal if you are near the router. Distance is what affects coverage the most, so if you’re close to the device you shouldn’t have a problem. But sometimes even if you are a few meters from the access point you could have failures and see that the signal arrives weak. There are a few main reasons.

Interference with other devices

The first reason is that there is some interference with other devices. This is common if you have devices that work on the same frequency, such as the Bluetooth or even a microwavewhich works on 2.4 GHz. This will affect the WiFi connection and you could have a bad signal, even if you are close to the router.

What should you do in this case? The ideal is to always have the router in an isolated place, without other devices nearby. You should do the same if you are going to connect from a mobile or computer. The interesting thing is that they are away from other devices that could be interfering and creating problems.


Something similar can happen with possible obstacles. Maybe you are close to the router, but there is walls or walls that may be affecting coverage. This will make the signal very weak and you will have less speed or you will not even be able to connect and you will have continuous errors.

But you should not only take into account the possibility that there are walls or walls. There are also other obstacles that can affect the signal. For example a sheet metal it is something that could seriously affect the quality of WiFi coverage.

The network card is malfunctioning

Another reason is that the network card of the device with which you are trying to connect is broken or has a problem. If, for example, you try to connect from your computer and you see that the signal arrives very weak even though you are next to the router, there may be something wrong with the network adapter.

What you should do in this case is to see that everything is fine on the card. For example, make sure that you have the latest drivers installed or that the antenna, if it is an external card, is not loose. If everything seems fine, it may be an internal problem and you should try another USB network card to see if it works better.

But the problem could also be in the router. Maybe it doesn’t output signal properly. If you see that the signal does not arrive well even if you connect with other devices, then it is most likely a problem with the router if all of the above that we have explained is not the reason.

You can try to restart the router, verify that it is updated correctly and see that the configuration is correct. Even if there are intruders on the network, they could be affecting the quality of the signal and that translates into coverage problems.

In short, these are some of the main causes if you see that the WiFi signal is very weak even though you are close to the router. It is a problem that you can solve if you follow these tips that we have given.
