Personally, I do not use the “auto” channel feature because it does not always find the best channel, may suddenly change causing wifi interruption, and the algorithm is a mystery to me.

When not repeating the upstream wifi, I just set specific broadcast channels for both 2.4GHz and 5.0GHz bands. The free “Wifi Analyzer” and “WiFiman” apps on my smartphone display nearby access points and helps find an appropriate channel.

Frequently, the 2.4GHz band is very congested, so there may not be much to choose from. To minimize further congestion, I only use 20MHz channel width on 2.4GHz. The 5GHz band is usually much better in terms of less congestion and higher speed.
