Channels other than 1, 6 and 11 are effectively non-functional in today’s spectrum environment. They never really were great in the first place, and no one should have been allowed to use them domestically. This is hindsight speaking unfortunately, so there’s nothing to do about that now. The other channels overlap on both sides with 1/6/11, only causing worse interference, not fixing anything.
For myself, I would prefer that my devices were fully offline instead of dealing with an unstable signal in high interference zones. It’s much easier to troubleshoot “it works” vs “it doesn’t work” than it is to diagnose “sometimes it’s good, but sometimes it’s bad.”
Manually select the channels you want, but I will highly recommend that you still only use 1/6/11. There is not currently a way to tell the auto selection to keep the broadcast alive in a fully congested environment.
