1* My computer is connected by Wifi to the modem / router on the 5 GHz band, (let's say) canal 100.
2* After a certain amount of time, the router switches *itself* the canal to 36 or 52.
This amount of time is vary variable and independent of what I'm doing on my computer, hence the difficulty to describe the circumstances.
3* There is no indication that the connection is lost. There is no attempt to connect on the 2.4 GHz band, even though I have a connection profile. Then, syslog and kern.log start to grow endlessly, see bug description.
With previous versions of Ubuntu:
1* and 2* Same.
3* The connection is lost but very shortly after that the Wifi card connects on the 2.4 GHz band.
