How to Choose the Best Wi-Fi Channel for Your Router

Deep inside your router settings, you are able to change the channel that your router broadcasts its signal. 2.4GHz and 5GHz are the most common frequencies for routers. As such, they are short range signals. If you live far away from neighbors, then the signals do not interfere with each other. If you live close to other people broadcasting their signals, you may find a spotty connection or slow speeds due to interference.

Here's how to choose the best possible channel for your router.
