WPA-EAP (ath driver): trouble maintaining connection

Sun Feb 22 17:00:26 PST 2009

(Note: I posted this to the freebsd-net@ mailing list about a week ago
but never received a response. I was hoping someone on this list could
offer some suggestions.)

Hello,

I have been having trouble maintaining a wireless connection at my
university, which uses the WPA-EAP protocol. I have played with my
wpa_supplicant.conf file, but haven't found anything that works. I
don't seems to have any trouble at home using a Linksys AP and
WPA-PSK. I was hoping someone here could point me in the right
direction---I am not very familiar with WPA and wireless
networking. Error messages and other relevant information below. (You
will notice that I lose connection every 5-10 minutes.)

Thanks in advance.
