Mohammed, Thanks very much for the response. Yes I get "Operation not supported": # iwconfig wlan0 modu 11b Error for wireless request "Set Modulation" (8B2F) : SET failed on device wlan0 ; Operation not supported. ...so what does this mean; what are my options here? In view of the fact that the capability of changing modes (from 'g' to 'b' ...etc.) is an essential requirement, am I using the wrong driver ...is there a different driver that supports this chip? Or is it that there's no driver that supports this chip so that I would have to put this functionality into ath9k myself if I want it? Thanks again for the help. -Patrick > >Hi, > >On Thu, Aug 23, 2012 at 2:26 AM, Patrick Connolly <pjc999@xxxxxxxxx> wrote: >> Hello, >> I'm new to ath9k and in need of some basic/rudimentary help. >> I'm working with an Access Point that uses the ath9k/mac80211 >> driver combination to talk to an Atheros AR9285.
