You can get all supported channels for a certain interface with: ifconfig -v wlan0 list chan Compare that list on AP and client side. Just wondering, did you set a countrycode/regdomain via ifconfig country or ifconfig regdomain? I remember that there are some issues and you might actually end getting less channels then there are actually supposed to be. -- Bernhard
