I got tired of having to change the channels due the surrounding AP's continuously moving over onto the same channel that I use, so I decided to try the auto channel. Despite everyone saying that that doesn't work and the first channel is always selected, that does not seem to be so. It is selecting channels and while I do not quite agree with the 2.4Ghz selection, the channels chosen for 5GHz are empty, so a good choice.
So, is this feature working or not? This is the latest 19.07 with non-ct firmware.
