Subject: [ath9k-devel] Delayed transmission configuration switching
Date: Mon, 16 Jun 2014 17:35:13 -0400 [thread overview]
Message-ID: <539F6311.4040907@mailservices.uwaterloo.ca> (raw)

Hello,
We use the Ath9k driver for our 802.11 research projects. 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
