Atheros Wireless Errors

Some disappointing news. When I rebooted for some ALSA Configuration changes -which didn't help either - wifi was dead again and I could not log on to my WPA2 network. I could see all networks, but not log into mine (others are all secure).

in nm-system-settings.conf I still have the same settings as before:

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=true

But I cannot connect!

dmesg output shows:

This really is starting to turn me off.

Well and when I reboot again it all works?#$! Does anybody know why this is happening?
Maybe because I am too close to my Dlink Wireless router? Or is it just because ath5k is just still buggy under the latest kernel used by Ubuntu? Here is the dmesg after reboot:

You can see the wireless is started up, but it takes quite some time...

Well wireless using my Atheros Card works now 90% of the time, but it needs to recalibrate all the time. It is clear wifi is having a hard time on Ubuntu Jaunty Jackalope with an Atheros wireless card and a Dlink wirless router. Here is the tail of my debug report:

Just wanted to mention his. I am quite satisfied now, but it is clear Atheros is not running smoothly under Ubuntu yet..
