thanks for the reply,
I think i am not generation that much traffic (iperf3.exe -c 10.80.250.7 -u -b 10m -i 1 -f m -l 1500 ) 10mb of big udp packets shouldnt impact the other users. It takes very few seconds for this to kill the other web traffic (if we are pinging with small packets at the same time they go trough wich is strange...).
All this makes my think that i and not starving the "air".
I also have clients saying that they have problems in APs in wich i am not doing the tests.
When i put the SSID in decrypt mode i also stop this behaviour (it drops my large packets but other clients dont have problems)
When the controller drops packets that arrive in the GRE tunnel out of order (i think 802.11 data packets) do they drop all of sequencial packets also until the "good" one arrives?
Also does the AP puts more then one 802.11 data packets per GRE packet (from different users).
Because only in this scenario i can see why the droped packets of my sessions are braking the other user traffic (or something at the AP level...)
PS - I have opened a TAC case so i guess they will use the Airwave for advanced debug. I am also going to connect a AP directly in the same switch that the controllers are connected to take all other network gear from the equation.
