Hi,
My sister recently bought a new laptop which has an internal Atheros
wireless card.
Installing Ubuntu 10.04 on the laptop, everything works perfectly
except for said wireless card.
Using the ath9k driver, the card can find wireless networks
broadcasting their SSID (either using Ubuntu's network-manager or
using 'sudo iwlist wlan0 scan'). The problem is AP association keeps
timing out. My wireless network is WPA-PSK (Personal v1) protected and
I tried connecting using both Ubuntu's network-manager and
'wpa_supplicant' with a configuration file similar to my own working
laptop's one. It didn't work. Trying the proprietary ath_pci module
didn't work either (I couldn't even list neighbooring wireless
networks).
I also tried disabled all encryption on the AP and trying to connect.
This resulted in messages like the following in 'dmesg':

Lastly, I noticed the wireless LED stays orange at all time, turning
blue only once at the beginning of a connection try (whereas my
working laptop's LED turns blue to then keep flashing to indicate
network activity).
Thank you for your attention.
P.S.: Please note I won't be able to give anymore test result past
friday 2010/06/25 as the refund period will end that day and my sister
won't keep the laptop if I can't get the wireless to work.
Regards,
Olivier Diotte
