On Windows, you are going to need to download a separate utility such Acrylic Wi-Fi. Once you have downloaded the utility, run it and Scan for networks, as before making note of the most popular ones.
On an Android Phone/Tablet, head to the Play store and download Wi-Fi Analyzer. Open the app and as before, Scan networks and make note of the popular channels.
Fixing the problem
We are going to need access to your Router’s admin page to make the changes, the most common URL to access the settings page is http://192.168.1.1, input that in your web browser. If nothing happens, then refer to the manual that comes with your router for the correct address.
Now you are going to find the Wi-Fi settings page, once there, look for the Channels options and select the channel that is being used the least, save your settings and exit.
That’s It! You’ve now successfully decoupled your Wi-Fi from a crowded channel, this should hopefully bring you some much-needed consistency in your home network.
