The above are informative, and are letting you know that your AP is not capable of supporting the highest throughput.

This one indicates that there was a call to disassociate when the device was not associated. It might have been informative to have seen the logged messages earlier than 436.155474 seconds.
Johannes: Why is this a WARN_ON condition? Certainly, the returned -ENOTCON does the right thing, even though some part of the system got confused.
