Might be. I'll try compiling linux-next and see if it helps (could be few days, I need to setup this box for the task first). In the mean-time I played with things a bit. I've created /etc/modprobe.d/cfg80211 as follows: options cfg80211 ieee80211_regdom=US This seems to have set user preference so that enabled frequencies are set correctly initially (and also instead of switching to "world" (00) when it looses connection to my AP, now it switches to US instead). Next, I installed the "iw" tool, and it showed interesting results. When connected to my Apple wireless router (5GHz WiFi-a/n network), I get: # iw reg get country 98: (5170 - 5250 @ 40), (3, 17) (5735 - 5835 @ 40), (3, 30) The log files show switching from US to 98 and back to US, but output of iw reg get always claims country is 98 with above two frequency ranges. On the other hand, if I connect to my Linksys router (2.4GHz WiFi-b/g network), there's no mention in log files about any switching between regulatory domains, and output of iw reg get shows country correctly set to US: # iw reg get country US: (2402 - 2472 @ 40), (3, 27) (5170 - 5250 @ 40), (3, 17) (5250 - 5330 @ 40), (3, 20), DFS (5490 - 5600 @ 40), (3, 20), DFS (5650 - 5710 @ 40), (3, 20), DFS (5735 - 5835 @ 40), (3, 30) However, after several minutes, the connection to my Linksys WiFi router fails again with nothing useful logged, the green LED on WUSB600N wireless adapter goes off permanently, and attempt to connect to any network (either of my two WiFi networks) fails. NetworkManager still shows list of all networks (on both 2.4GHz and 5GHz bands), and output of iw reg get still shows country set to US and all frequencies listed for US as per above. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
