[ath9k-devel] Progress on Ath9k HT support on Adhoc mode

[Peizhao Hu <peizhao.research@gmail.com>]

Hi all,

I would like to confirm my findings. My test platform configurations are 
follow.
Board: pcengine alix3d2
Linux kernel: 2.6.35 from linux-wireless git
Driver: compat-wireless-2011-01-17 and iw-0.9.21 with the patch 
suggested by Alex.
Radio card: Ubiqiti SR71a on channel 36 with HT40+
Measurement tool and settings: Iperf, UDP, 100Mb offered load

Recored throughput: 50-54Mbps (one antenna); 78-80Mbps (two or three 
antennas).

Any one have idea how I can achieve 100Mbps+ throughput with my current 
setup?


By the way, I tried to the "[PATCH 1/1] compat-wireless: Fix ath9k debug 
log issue" patch. However, I am still getting these error logs.
