Hm, okay. I'll go try and reproduce this locally. can you do an 'ifconfig -v wlan0 list scan' and 'ifconfig -v wlan0 list sta' and privately email it to me? That way I can try to see what environment you have. the 2x2 NICs don't do rate control at the moment, so I bet part of the problem there is the default fixed value is terrible :( -adrian On 23 June 2016 at 09:23, Otac=C3=ADlio <otacilio.neto@bsd.com.br> wrote: > I did the tests with two adapters.
