Please outline the steps you follow to connect. – evgeny Oct 16 '10 at 7:00
@Evgeny, thanks for offering but I found by manually setting the MTU, I could get it to work! :D – Axeman Oct 16 '10 at 7:32
can you accept your own answer so it stops being listed as "unanswered"? thanks – maco Oct 16 '10 at 16:12

I solved this 20 minutes later. I had done a lot to try to get networking working. I was just about to delete a line in /etc/modprobe.d/blacklist-ath_pci.conf when I decided to give nm-applet one last shot and after filling out the SSID and other information for my network for the two-dozenth time, I just decided to manually set the MTU value.

After applying, I finally got the coveted ¨Connect¨ dialog! I had been reading about this mythical beast all evening.

So if anybody looks in here, sometimes with an Atheros 5K, you have to manually set the MTU.
