I have a MacBook Pro 8,2 with the BCM4331 wireless chip.  I pulled the
firmware (666.2, 2011-02-23 01:15:07) using b43-fwcutter, and am running
Fedora 18 (tried up to kernel 3.9.6-200.fc18.x86_64 from updates/testing
with the same results).

My problem is that it deauthenticates from the AP every 5 minutes (it
then immediately reconnects).  From what I've read, it looks like this
chip is a little "different"; any ideas/suggestions to help get this
working better?

Example dmesg chunk:

[  948.115374] wlan0: associated
[ 1249.636655] wlan0: deauthenticated from 00:a0:c8:xx:xx:xx (Reason: 1)

My table shows that a "Reason 1" deauthentication is for "unspecified reasons". Does anyone know why these might occur?

What type of encryption are you using? If it is a re-keying type such as TKIP, what is the interval? You should find that on the setup page of the access point.

BTW, your mailer is set up strangely. I get your address when I do a plain Reply, but a Reply All from Thunderbird only got the b43-dev mailing list. I had to add your address manually.

I also added the linux-wireless ML to the reply as some of my questions are more likely to be answered there.
