Same problem here too on a macbook pro 2.1. Disconnections every 2 minutes and
I have to wait 2 minutes again to regain connection. The link is of very poor
quality : less than 3mbit/s. (can't even watch my ISP's tv streaming service)
Now I'm connected manually via iwconfig. No disconnections and good speed so
it's not a driver problem (ath9k).
Using jaunty alpha6 fresh install and up to date. Network-manager

The complete syslog file is attached and contains association errors at
the beginning because I changed my AP security from WPA PSK to WEP (just
in case).
