My laptop connects only to 11ng, but here's the weird thing: I see at least one WiFi network on channel 36 through "ifconfig wlan0 scan". I thought that 11a is required to see channel 36, but as a total WiFi noob, I might be totally wrong. Anyway, my question is how to check if my iwlwifi is new enough and why do I see network on channel 36? Thank you! Regards, meka
