    As WiFi has become very popular, there is (almost) a connection and a modem in practically every home. Their range is limited to a few tens of meters - or less, if we talk about the AC standard, if there is not much interference between the modem and the device. However, in some densely populated areas, this interference does occur.

    How WiFi channels work and why you should care

    Il channel of broadcast WiFi it is neither more nor less the frequency with which data is sent and received to and from the modem. Its operation is to put it plainly like that of a road: if a lot of data comes and goes, there will be a traffic jam. Why should you fear these traffic jams? Because they are not entirely up to you.

    Your connection may slow down simply because the WiFi travels through a very busy channel, which is used by virtually all neighbors. Sometimes modems are configured to use one of the available channels, which causes constant dips when there are many modems and devices connected in a very small area.

    Once opened, you will see that our network is the closest, so its intensity is greater. However, you can also see which frequency is the most saturated of all. If you click on the eye icon that appears above in Channel Score, it will show the same data in the form of a star rating.

    Obviously, the best channel for WiFi it is the one with the most stars, the least busy.

    How to change the WiFi channel on your modem

    Now that you know what you want to do, it's time to log into the modem as we have explained here. This is much easier to do if you have an upper-mid-range modem and your own operating system. You can even change the values ​​from your mobile.
