Hi! If 11n is available, it will "upgrade" your AP interface to be 11n. Just do this: ifconfig -v wlan0 list chan If it shows 11n HT20 and HT40 channels, then it will just be upgraded. next, don't set + or - - some channels require HT40+ or HT40-. They're not supposed to overlap! Just do: (whilst creating things) ifconfig wlan0 channel 52:ht/40 ifconfig wlan0 up On 18 June 2013 11:55, Peter Ankerstål <peter@pean.org> wrote: > Hey, > > Sorry about all these questions but I frustrated now. :D > > Im trying to get ht/40 but I don't seem to get it right.
