Several Debian users (cc'd) have reported a regression in iwlagn in
Linux 3.1, not fixed in 3.2.  The full bug log is at:

http://bugs.debian.org/651199

To summarise, a WPA-TKIP managed connection stops passing traffic and
the kernel log shows the message "WPA: Group rekeying".  This apparently
doesn't happen if the connection is in heavy use at the time or with
module parameter swcrypto=3D1.  WPA2 is not affected either.

Q.  Which is the greater problem in the world today, ignorance or apathy?
A.  I don't know and I couldn't care less.
