Atheros AR9485 freezes whole system

On Acer Aspire 7250, AMD Dual-Core E450, “AMD” Radeon HD 6320, Acer Nplify 802.11b/g/n
OpenSuse 12.1 64 bit

           product: AR9485 Wireless Network Adapter
           logical name: wlan0
           width: 64 bits
            clock: 33MHz
            capabilities: pm msi pciexpress bus_master cap_list rom ethernet physical wireless
            configuration: broadcast=yes driver=ath9k driverversion=3.1.9-1.4-desktop firmware=N/A latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn

The wireless driver comes from OSS repo. At first glance works perfectly showing all available connections.
By giving in the security key, the wireless connection starts and freezes the installation at 100%.
However, eth0 works well.

Has somebody any idea how to fix that? Of course I could plug in a second wireless, but the solution is not very elegant and I am not the laptop owner. I care about the image of our distribution :slight_smile:

Thanks in advance

No, I have no idea to “fix that”.
I had/have the same problem with the Acer 7250. The problem also appears with the Gparted live-cd. My conclusion is that is not a openSUSE-12.1 problem. My solution was to install a D-link DWA-140 adapter, which works perfectly on another 12.1 system.
However, once I had given it the WPA2 password, I had to blacklist the Atheros drivers to prevent them from being first to connect to the AP and then to freeze the system.
Modules blacklisted: ath, ath9k, ath9k_common and ath9k-hw.
Should you find a ‘real’ solution, please mention it in this thread. Thank you.

Hi.

Maybe too late but at least a solution.

Today I had the same problem with a Acer Aspire 5250-0619 (64bits) laptop and using 12.1 GNOME.

Thanks to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/989566 I could fix it, except that instead of issueing the command I re-booted the laptop and that was it.

It works like a charm.
