ath9k can't associate with AP

Arch Linux can see the wireless network interface with ath9k on Acer Aspire 3820TG that has "Acer Nplify 802.11bgn". It can also scan for networks, but it can't associate with any access point.

I tried using manual configuration with ifconfig, iwlist and iwconfig. I also tried the rc.conf way and cnetworkmanager.

Linux markus 2.6.35-ARCH #1 SMP PREEMPT Sat Oct 30 21:22:26 CEST 2010 x86_64 Intel(R) Core(TM) i5 CPU M 450 @ 2.40GHz GenuineIntel GNU/Linux

05:00.0 Network controller [0280]: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01)

# lsmod | grep ath
ath9k                  77595  0
ath9k_common            4902  1 ath9k
ath9k_hw              286570  2 ath9k,ath9k_common
ath                     8822  2 ath9k,ath9k_hw
mac80211              189270  2 ath9k,ath9k_common
cfg80211              144231  4 ath9k,ath9k_common,ath,mac80211
led_class               2363  1 ath9k

After I set up the interface and essid I only get the outputs below. Note that the AP is not associated. The tested AP works with another computer and doesn't have encryption.

wlan0     Link encap:Ethernet  HWaddr 20:7C:8F:05:D8:77 
          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

wlan0     IEEE 802.11bgn  ESSID:"Niskasen" 
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off

'network' daemon says that you should try to increase the wireless timeout (which didn't help) and networkmanager tells that association takes too long.

What should I try to do?

Re: ath9k can't associate with AP

dmesg show this when trying to connect with networkmanager:

ath9k: Two wiphys trying to scan at the same time

I also found this silimar problem that was solved: http://ubuntu-virginia.ubuntuforums.org … ?p=6117475

However the solution doesn't apply because this Acer doesn't have /sys/devices/platform/asus-laptop/ or anything similiar I could find.

Re: ath9k can't associate with AP

Actually I found out that the network card is working and it was just my own mistakes.
