Hi, I just tried ath5k from compat-wireless-2010-05-12 in hope that connectivity might be fixed for AR5211 (168c:0012) but got this message when I loaded the module: $ sudo modprobe ath5k WARNING: Error inserting mac80211 (/lib/modules/2.6.32-22-generic/updates/net/mac80211/mac80211.ko): Unknown symbol in module, or unknown parameter (see dmesg) FATAL: Error inserting ath5k (/lib/modules/2.6.32-22-generic/updates/cw/ath5k.ko): Unknown symbol in module, or unknown parameter (see dmesg) And this is what dmesg showed: [ 79.539144] ath: disagrees about version of symbol wiphy_apply_custom_regulatory [ 79.539158] ath: Unknown symbol wiphy_apply_custom_regulatory [ 79.539707] ath: disagrees about version of symbol freq_reg_info [ 79.539714] ath: Unknown symbol freq_reg_info The module that ships with the kernel loads fine but there is no connectivity at all when I try and connect to this WPA-PSK network of mine. When I try and manually connect with wpa_supplicant it just times out. I can get the wpa_supplicant message if it's relevant but lets just get this down before ndiswrapper locks my system! :)
Provide the output to: modprobe -l cfg80211 modprobe -l mac80211 modprobe -l ath modprobe -l ath5k

There you go, that's the issue. You have the ubuntu linux-backports-modules package installed but yet you also tried to install compat-wireless and have some mixed modules from both. rm -rf the /lib/modules/$(uname -r)/updates/ directory completely and then do depmod -a, then reinstall compat-wireless fresh.
Ohh, what a rookie mistake. When you say it I even remember reading that linux-backports should be removed. Sorry to waste your time!
