About a year ago there was a > discussion of this feature of minstrel. Thanks, that must be this thread: http://comments.gmane.org/gmane.linux.kernel.wireless.general/84459 I think that explains much of my confusion. I too would like a way to really disable RTS for testing. On a mostly quiet channel, sending UDP frames one way, I still see lots of RTS/CTS, which must mean there are lots of retries (assuming Minstel-HT is cause of this). Not what I wanted to find at this late date in my release cycle :P Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
