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.

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.

'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?

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.

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