Yes, adding bandwidth config to existing command. Something like this, iw offchannel [HT40+|HT40-|80MHz] > Still I guess I'd like to see an actual reason for it. Wide band scan is actually moving to a off-channel for a specified duration to capture 40, 80Mhz data frames. So, I hope offchannel would accommodate this extension. -- Thanks, Sathishkumar
