Hi I've been fighting these wireless drivers for a few days and just recently i noticed that the model the Wireless controller appears in lspci is different sometimes. This is the data i have after installing Ubuntu Server 64 bit

~# lspci -k 
....
04:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) 
        Subsystem: AzureWave Device 1d89 
        Kernel driver in use: ath9k 
        Kernel modules: ath9k

ran some updates, restarted, all was good, all though it did say that linux-headers-server linux-image-server linux-server where beeing kept back.

After that i installed ubuntu-desktop (aptitude install ubuntu-desktop --without-recommends) restarted and not only is the wireless not working anymore, but the hardware is listed as a different card

~# lspci -k
....
04:00.0 Ethernet controller: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01)

has no available drivers for it, still i tried to modprobe ath9k, they show up in lsmod as loaded, but still iw list shows nothing.

this is what it looked like before the ubuntu-desktop instalation

What's with the hardware change? If it has 2, how can i make the AR9285 always load and disable AR5008, or, is it the same and it's just showing it different? :|

Oh and I've tried this on Ubuntu 10.04 server, xubuntu 12.04, ubuntu 12.04 desktop and server.

Thanks in advanced.

-- Here's some more info, i have it setup in 2 hard drives, 1 works and the other one i'm using to figure it out

The one that works...

Update

I've noticed that if i blacklist the ath9k and ath9k_common modules lspci gives me the AR9285, but then I need to modprobe ath9k for it to work, does this make any sense? If so, why?
