Finding the Best WiFi Channel for Your Router

WiFi channels matter when you live in an apartment where there are many other networks close to you. Having the same WiFi channel as the nearby networks will cause a lot of interference with their networks. It is best to find the WiFi channel that is used less by your neighbor networks. To find the WiFI channel that is less used, you need to find the WiFi channels for all the nearby networks. This will help you in figuring out which WiFi channel is used by fewer networks and that will be the best choice. We are going to show you the methods of different platforms.

Windows:

For most 2.4GHz channels, it is better to use channels 1, 6, or 11. By using one of these channels, it will make sure that it doesn’t overlap with the other channels. Also, look for the channel that has the least number of wireless networks available on it, it will be the best channel for you. Each channel is about 20MHz to 22MHz wide, but the 2.4GHz is only 100MHz. So, to include all 11 or 13 channels in this much space, they need to overlap each other. Whereas 5GHz will have much more space for channels and the channels won’t overlap with it. 5GHz has less range but has greater potential for higher wireless speeds and in general, it has less consumption than the 2.4GHz band.
