This small change will prevent interference on your WiFi

It is important to have a good Internet speed and when we connect through Wi-Fi it is not always possible. In this article we are going to talk about how a small change can make it so that there is no interference and thus prevent the connection from being slow, with cuts and, ultimately, having a worse performance. It is something that can happen from time to time or be something habitual. However, correcting it is easy if you follow the advice that we are going to explain in this article.

Switching bands avoids interference

This small change will prevent interference on your WiFi

Why does Wi-Fi interference appear? One of the reasons is when we connect the router or some device near other electrical appliances. For example, putting the computer near a microwave, which works at a frequency close to 2.4 GHz , can cause connection problems.

We can also have interference from other devices, which are not always going to be in our home. For example, if there are other routers from our neighbors that are working on the same channel as our device or on a nearby one. In this case there will also be interference and we will have problems for the connection to work correctly.

Now, when does this most often happen? This will almost always happen when we are connected to the 2.4 GHz band . There may be interference with a microwave or other devices that use Bluetooth. Also, the 2.4 GHz band has fewer channels and they overlap. This means that we may be connected to channel number 6 and have several neighbors using that same channel or other nearby ones, such as 5 or 7.

To avoid interference, all we have to do is switch to the 5 GHz band . This will make the connection work better if we have other devices nearby that can interfere, such as a microwave, as well as avoid interference from our neighbors, since this band has more channels and they are not overlapping. Therefore, a small change can make the connection better.

Diferencias entre 2.4 y 5 GHz

The 5 GHz band has disadvantages

As you can see, simply by making a small change such as using the 5 GHz band instead of the 2.4 GHz you can avoid Wi-Fi interference. Of course, as long as your connection malfunctions due to this problem, you will see positive results. If the reason is another, you will not see big changes.

But this does not mean that the 5 GHz band is always better. In fact, it has important disadvantages. One of them is that it has worse coverage . The distance it reaches is less than that of 2.4 GHz, although it does offer higher speed as long as the conditions are optimal.

It also has the disadvantage that there are devices that are not compatible . Although today most are dual band, there are still many that only work in the 2.4 GHz band and in these cases you could not simply change the band to avoid interference.

Therefore, as you can see, it is possible that your Internet connection improves if you only change the band to which you connect. Try to go from 2.4 to 5 GHz if you see that your connection is not working well, that you have interference with your neighbors or other electrical devices that may be in your home. You can see the channel and Wi-Fi band you use.
