Pavel,
 
Now I used modprobe and wlanconfig ..... I see my AR5212 is up because I see wireless light is blinked. I do see nois level = -96 dbm, signal level = -96dbm.
But "iwlist ath0 scan" returns "no scan results" and I see codes are executed.
 
Should I check /etc/modprobe.conf and /etc/sysconfig/network-scripts/ifcfg-wifi0 or ifcfg-ath0?
 
Also, when Linux PC reboot. I see configure IP for wifi0 failed.
 
Any else I should check?
 
Thanks.

It seems to me that scanning is currently broken in master mode. It's
working in managed mode. I don't think using "insmod *.ko" is a good
idea. Try this instead:

modprobe ath_pci autocreate=sta
