Today we are going to explain how to change the channel of your WiFi network, one of the steps you have to take to improve your signal and gain power. WiFi routers use specific amounts of channels. For example, in Spain and Europe those that use a 2.4 GHz range have channels that go from 1 to 13. There are very few channels, so there may be some that are saturated when there are many routers around. In addition, the channels overlap, thus creating interference with each other.

The 5 GHz ones have 25 non-overlapping channels, so the problems are basically going to be in your 2.4 GHz WiFi. By default, your router usually chooses a channel automatically, and what we are going to explain to you is how to tell you to use a certain channel. To do this, we will first tell you how to identify the least saturated channel to know which one you should connect to.

First check which channel you should switch to

As we have said before, the vast majority of WiFi routers broadcast in the 2.4 GHz band, which goes from 2.412 MHz to 2.472 MHz and is divided into 13 channels. These channels overlap each other, so that each channel occupies a part of the spectrum of the underlying ones. As you can see in the image, an example is that of channel 1, whose bandwidth reaches channel 3 generating interference with it and vice versa.

As we said at the beginning, the best solution would be to use the 5 GHz band. However, not all routers include it, and not all your devices are compatible with it. Therefore, if you have to use the 2.4 GHz band, the best solution to improve your connection is going to be to find the channel that is less saturated.

To analyze the channels around you, we are going to use the Android WiFi Analyzer application, although you will also find other alternatives that do the same job. However, this is free and allows you to analyze the channels without giving your credentials. Download it, and when you run it you will see how the channels around you are. For a better analysis, click on the View button that you have at the top of the screen.

An options window will open, in which you have to click on the option Channel score. This serves so that instead of a graph, the application will rate the channels with stars, showing with more stars those that are less saturated, and therefore those that are best for you to use.

Once you enter this section, click on the left side of the screen where a red text appears. A window will open in which you have to choose which is your WiFi connection. You will do it because the names of all those that come to your mobile appear, so that you will only have to click on yours.

And that’s it. When you choose your WiFi, the list of channels and their scores will change to suit it. On the left you will have all the information you need. First they will tell you which channel you are currently using, and then In Better channels you will see which are the ones he recommends you to switch to for being less saturated. What remains now is to switch to those channels to improve your connection.

Once you know which channel to move to, you have to change it. For this you have to enter the configuration of your router. You can do it by opening the browser on your computer or your mobile, and typing the address 192.168.1.1 in the search bar.

You will have to enter the username and password for access, which are usually admin / admin, 1234/1234 or a combination of both. If they are not, you can simply search for router OPERATOR password with the name of your operator. From now on, the interface may change depending on your router and operator, but the options at almost all times will be almost always the same. I will continue with the interface of my ZTE F680 router.

Once you enter the configuration, click on the Network option of the column in which the configuration options of your router appear. This will display the options related to your network, including the settings for your 2.4GHz connections.

When the Network category options are displayed, you have to click on the name of your 2.4 GHz connection, which in the capture with my ZTE F680 router is called WLAN Radio2.4G. In the event that your router also has a 5G band, it will also appear, but in the name they will always specify which is 2.4 GHz and which is 5GHz.

Now, click on the box next to Channel to display the list of available channels. By default it will be in auto mode to automatically assign one to you, but in this list you must click on the channel that we have seen before, which is the one with the least saturation. Once you choose the channel, simply click Submit to apply the changes and you’re done.
