This interference is probably co-channel interference or noise. That is not shown most of the time in the interference types view. But first check if you actually have the detection of it enabled under Wireless -> 802.11a/n/ac/ax -> CleanAir.

Ok that looks good. In any way, it only reports detectable Interferences (the ones listed in the box). If the interference type is unknown, then it doesn't list them on the interference devices page. In that case it's mostly noise or co-channel interference.

Yes it's well possible that this is a source of the problem.

Make sure you have under RRM the functions DCA and TPC enabled and you might want to switch to 40 or even 20 MHz channel width.
