Quote from http://wiki.archlinux.org/index.php/Wireless_Setup: If you want to enable more channels on Intel Wifi 5100 (and quite possible other cards too) you can do that with the crda package. After install, edit /etc/conf.d/wireless-regdom and uncomment the line where your country code is found. Add wireless-regdom to your DAEMONS in rc.conf and restart (which is the easiest thing to do). You should now, when writing sudo iwlist wlan0 channel, have access to more channels (depending on your location).
