wlan0: deauthenticating from 00:05:b4:05:ac:7d by local choice (reason=3) when using ath9k driver and NetworkManager with Wireless Network controller [0280]: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01) on ASUS EEE PC 1005HA in Ubuntu 10.04 LTS

My wireless isn't working in newly installed Lucid, but it is with Windows XP. After referring to some forums, I got it to work temporarily, but now it is out again. I am new to Ubuntu and this is over my head. Would someone please help me settle this issue for good? Any help would be much appreciated.

Model: EEE PC 1005HA

ath9k driver

Here are the diagnostics I ran after looking at other forums.
