Yes. That is a hardware limitation.
I think if a client connection is made on a different channel, the AP is switched to match.

In particular, the way it works (with one primary mode) does not now seem correct (given what we know about the wifi stack now). I have now re-worked the wifi driver to work as follows:

I am now trying to convert the old commands to retain backwards compatibility (but I would like to deprecate those, long-term). The ‘auto’ system also needs conversion (but again, I’m trying to make it backwards compatible).
