[Bug 548992] Re: Wireless connection frequently drops [deauthenticating by local choice (reason=3)]

[Tony Cox]

The wireless on my Dell Latitude D630 broke on upgrade. My wireless now
continuously cycles between connection/disconnection. It is useless. I
can't believe an upgrade broke something so important.

dmesg reports a continuous log like this:

Not sure how to fix this - above did not fix my connection.
