ath9k + ar9280 oddness

view full story

http://www.linuxquestions.org – History of the Problem:I was at Milwaukee Airport earlier this week, authenticated with their AP but was unable to get an IP address. I killed wpa_supplicant and went to run it again, this time, there was no authentication. Running 'iwlist wlan0 scan' returned with no results. This has been the case everywhere since then. The card was working like a champ up until that fateful day @ MKE.I upgraded my kernel to today in an attempt to get my roommate's rt3572 USB wifi card running to no avail, but this is a separate issue. The onboard Atheros 9280 card worked under the default Slack64 13 kernel. I also tested the card under Ubuntu 9.10 and Backtrack 4 live distros, neither of those worked. I took a peek at the physical wireless card and the antennae are securely fastened. The laptop is a Dell Studio 1440/14z.
