We transmit every frame using a new transmission rate (MCS, short GI, HT20/40). We cycle through all different rates (96 rates in our 3x3:3 testbed). We noticed that when we change the transmission configuration (i.e. from Short GI to Long GI, and from HT40 to HT20) the next packet is sent at the previous configuration. MCS S-GI HT40 12 1 0 12 1 0 12 1 0 6 1 0 <--- supposed to be 6 0 0 (The sender claims that this frame was sent using L-GI) 6 0 0 6 0 0 It seems that the hardware did not have time to switch the configuration. Does anyone know if this is the actual reason and if there is any solution? Thank you, Ali
