wireless - Network Card Atheros problem Ubuntu 12.10



I installed ubuntu 12.10 and my wireless card seem to have a lower performance compared to linux mint (any edition) - I mean it worked fine there.
For example it cannot connect to a router placed in a room next to mine (1 wall) and it could do it in mint or windows.
My wireless card is:

02:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)
Are there any known issues for this card?



This is the solution for the problem



It's the old hwcrypt problem. In case you upgrade the kernel, and have no access to the web, don't blame network manager or wpasupplicant, create a file named



/etc/modprobe.d/ath9k.conf 



with the contents



options ath9k nohwcrypt=1


and reboot
