Karmic: Wlan Atheros AR928X ath9k: no fix works

[coffeecat]

Someone named sebz_ posted a solution that worked fine!

I commented the ath_pci blacklist in /etc/modprobe.d/blacklist-ath_pci.conf.

You check if ath9k (or ath5k) is loaded in /etc/modules

echo ath9k | sudo tee -a /etc/modules

Then you install

linux-backports-modules-karmic and linux-backports-modules-wireless-karmic-generic (and linux-backports-modules-wireless-karmic-generic-pae if you can but I didn't need it)

Reboot and all should be fine!

Simply installing the two backports-modules worked for me on this Acer laptop with:

06:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)

It was using ath9k, and still is (presumably a newer version), so I didn't bother with the system file edits. Working so far....

Famous last words.

Hi Prosis,

I was having the same problem with my Sony Vaio X111. I had tried everything I could (installing madwifi, ndiswrapper, turning of WPA, etc) but couldn't fix it.

I installed the 2 backport packages as you said, and it is much better.

Before the update:

- signal strenght was always between 20% and 65%, even if I was only a couple of meters from the base station
- hundreds off log messages from wpa_supplicant (disconnecting, searching, negotiating, reconnecting)
- needed to kill / restart my connection manually every hour or so.

After the update:

- signal strenght is 100%
- no more error messages on log files
- the connection is stable.

Thank you!
