Thanks for your help. Unfortunately, I still got this errors:
Error for wireless request "Set Mode" (8B06)
SET failed on device wlan0; Bad address
Error for wireless request "Set Frequence" (8B04)
SET failed on device wlan0; Function not implemented
Error for wireless request "Set Bit Rate" (8B20)
SET failed on device wlan0; Function not implemented
Cannot get driver information : Function not implemented
After completed driver installation, the interface wlan0 is up with my usb wireless adapter MAC address. When I typed #iwconfig, I saw the SSID, but I couldn't see the access point MAC addr. Do you think this might be the problem?
But when I tried #iwconfig wlan0 ap <MAC address>, I got the error like this:
Error for wireless request "Set AP" (8B24)...
I don't know what to do.... please help me... ;(
