I am having real connection issues with my D-Link PCI wireless card (runs the ath9k driver). It was automatically detected and configured in Maverick (10.10) 64-bit.

I get a connection, but it is much more flaky than it was under 9.04. It disappears, then comes back sometimes, but more often than not I need to reconnect. I was using Network Manager, but switched to Wicd, hoping that would help, but to no avail...

My messages log shows:

ADDRCONF(NETDEV_UP): wlan0: link is not ready
ath9k: Two wiphys trying to scan at the same time
wlan0: authenticate with ______ (try 1)
wlan0: authenticated
wlan0: associate with _____ (try 1)

?? Is Apparmor interfering with DHCP, or is this another problem? Forgive my ignorance, but I tried the Googs, and got stumped! I saw some webpages relating to problems with redundant rt* drivers being loaded in the kernel, but I don't seem to have that problem... (I think).

Any help would be appreciated. Thanks!
