Hi, Thanks to all for your responses. Yes, I am using packet type UDP for this test. I have set -b 300 M.
I have checked in the data rate table at http://en.wikipedia.org/wiki/IEEE_802.11n-2009 , for a 40MHz channel data rate is 150 Mbps for MCS 7(Max that AR9285 can support). My question is, - then how I can see 300Mbps at client side for one set up?
