I have a T60p running Ubuntu 8.10 (kernel 2.6.27-9-generic) with Atheros 
AR5008 wifi card.
I use wifi every day, switching between work and home wireless networks. 
All works fine.

Today I could not connect to the work wifi. It shows in NM, when I 
select it tries to connect, after a while the authentication required 
window pops up. Re-entering the (correct) authentication makes no 
difference. I've attached a representative daemon.log.

All my colleagues can connect fine and yesterday it was working fine. I 
can dual-boot into Windows XP, and that also connects immediately. I've 
installed no new software, changed no configs. The only related event 
was that yesterday we had to reboot ADSL router and wireless hub, but my 
machine connected fine afterwards.

Any ideas - either how to fix or how to debug further?

Thanks
Phil
