Connecting through wireless networks is very common today. We have a large number of compatible devices and that means we can access the network without using cables. However, sometimes we can have problems. It may even be that the WiFi works fine and suddenly starts to go wrong . Why is this happening? In this article we are going to talk about it and give some tips to avoid it.
Why WiFi is starting to get worse
Having a good Wi-Fi connection is essential if you want to connect IoT devices, since most cannot be connected by cable. Therefore, if you see that there are problems and the speed is not adequate, you must take measures to try to solve it as soon as possible and that the coverage reaches better, as well as maintain the speed.
There are more devices connected
One reason your Wi-Fi may be worse than before is because you have more connected devices . Although it is true that today’s routers or wireless repeaters support many more than they did a few years ago, it is still likely that there will be problems and start to go wrong when the number increases too much.
Think about the devices you connected via WiFi before and the ones you have now. Perhaps you have gone from connecting some other computer, mobile and tablet, to having televisions, smart light bulbs, NAS servers, electronic books… In short, many devices that are going to connect to the network.
This is especially going to happen if you use a WiFi repeater. Normally these devices have less capacity and there are more frequent problems. You might have difficulty connecting many computers to the network.
Conflicts with other devices
It is also possible that there has been some change in the electronic equipment you use and that generates conflicts. For example, if you have installed an appliance near the wireless router or repeater. This can make the signal weaker, unable to navigate normally, and even impossible to connect a device.
A clear example is if you have a microwave nearby, since they work at a frequency close to 2.4 GHz and that can affect the WiFi signal. It can also happen if you connect other devices near the router or the device with which you are going to connect to the Internet. That can cause the connection to start going bad.
To avoid this, the ideal is to connect the router or access points as isolated as possible from other devices. You should always select a correct location, from where you can best distribute the signal.
Do you have any malware
Of course, if you suddenly see that the WiFi starts to go wrong you should also think about malware . Perhaps you have mistakenly installed some software that is actually a virus and that is going to damage the system and make it worse. You may have connection problems and start to slow down.
In this case, what you should do is make sure that the system is protected and does not have any type of malware. Install a good antivirus and scan your computer to detect any file that could be fraudulent and remove it as soon as possible, so that it does not affect your privacy and security.
You have changed something
Your WiFi may suddenly start to get worse if you have changed something. For example if you have changed the wireless band to which you connect. If you are connected to the 5 GHz and you go to the 2.4 GHz, it will be slower. On the other hand, if you go from 2.4 to 5 GHz and move away from the router, you may have worse coverage.
Another change is if you have connected with another network card, for example if you have an internal one and another via USB. It is possible that the one you have started using has less power and that will cause the wireless connection to start to go worse, with more cuts and without being able to access from further away.
In short, these are some reasons why WiFi may start to go wrong. Ideally, you should take measures to achieve a good wireless connection, without cuts or problems of any kind. You can always keep in mind tricks to improve the wireless connection.
