Subject: [ath9k-devel] AR9220 AP mode 's  throughput with ath9k
Date: Thu, 02 Jun 2011 15:07:10 +0800	[thread overview]
Message-ID: <4DE7369E.6060003@dongniannetworks.com> (raw)

hi all,

Is there anyone who have evaluated ar9220's throughput with ath9k?

With this card and ath9k, the average tx throughput is about 120Mbps. I
thought with this card, it should be very easy to get 180Mbps (I can get
this result with my 9160 card).

With 20Mhz bandwith, under same environment, i can get more than 90Mbps'
tx throughput.

I have tested two cards from different vendors. And from packets
captured, it shows that there are lots of CRC errors, and most of the
packets are with MCS 12~15.

Any idea? Is this ar9220's 40Mhz' limits, or ath9k doesn't support this
card's full capability?

BTW:
I'm using 2.6.35 kernel, but with newer 2.6.38's compat-wireless driver,
no big change.

Best Regards,
kang haiyang
