Do a 'sudo make install' in your compat directory, and then 'sudo make unload'. Check 'lsmod | grep ath'. If anything is still present, unload all of them, along with mac80211, cfg80211. Then modprobe ath9k_htc. Of course, you can just reboot after 'sudo make install' and things should work. Sujith
