Hi,

very strange, now I can't reproduce the problem anymore, association
works with channel 12 and other ones, too!
I have no idea why it's now working...

Could this commit affect any link tolerance/timeouts, because I was
able to bisect the problem?

Not sure what happen, but please do let us know if you see the problem

tolerance.
