That's odd, firmware bug? But it's still odd since windows works?

Well, it's actually somewhat unlikely you'd break the law, although
possible, since eventually you'd get disconnected from the AP anyway?

In any case - your argumentation above isn't true because every device
listens for beacons, and if none are received then it should eventually
disconnect. That should be true even with your hack here.

In any case, I'm not really comfortable connecting to an AP that we
never ever receive beacons from. I can try to investigate why this
doesn't happen on windows and what we should be doing though.
