[ath9k-devel] not getting 11n rates

[sri ram]

Hi,
    I am trying to use the ath9k driver with a WMIA-199N miniPCI 802.11n
chip based on the AR9160 chipset. I am working on a machine installed
with Ubuntu Intrepid (kernel 2.6.27-7). I installed the latest
compat-wireless package. I also have a CISCO WRT600n 802.11n router
setup with a 40MHz channel in the 5GHz band (802.11n only). I observe
that the card is able to associate with the AP. But it is associating
with a rate of only 54Mbps. The router supports 802.11n rates up to
270Mbps and I observe that on windows an 802.11n card is able to
associate at 270Mbps. I tried using using iwconfig to set a higher
rate. But I get an "Invalid Argument" error. The iwlist wlan1 scan
also shows the maximum supported rates for the particular connection
as 54Mbps.

Should I use a different kernel/wireless-tools package to allow
connections at a higher rate?

Thanks,
Sri

Hi,
I am getting 11n rates with 2.6.27-7-9, so while you could you the  
wireless testing kernel which will give you 2.6.28 kernel it is not   
required.

One of the things you do not mention is your encryption.
The way I understand it, 11n will not wwork with WEP, you need WPA-PSK.

Please load ath9k with debugging enabled, as 'modprobe ath9k debug=0x00002000'
and post the output here.

Thanks Sujith and Brian.

Sujith,
Here is the output when I use the debug mode and dmesg:

root at 80211n-0:~# modprobe ath9k debug=0x00002000
FATAL: Error inserting ath9k
(/lib/modules/2.6.27-9-
generic/updates/drivers/net/wireless/ath9k/ath9k.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
root at 80211n-0:~# dmesg
...
[16392.012435] ath9k: Unknown parameter `debug'

Is this a known problem?

Brian,
I do not use any security on my AP or client. Even when I try to use WPA the
client does not connect. Can you let me know more about your configuration
so that I know what configuration works well?

Thanks,
Sri

[ath9k-devel] not getting 11n rates

[sri ram]

The card is working at the 11n rates!

Although iwconfig shows only 54Mbps, Iperf provides upto 150 Mbps UDP
throughput.

Thanks for the inputs!

FYI wireless-tools (iwconfig, etc) only supports showing legacy rates
(non 802.11n rates). To get the latest MCS TX bitrate you can use the
new iw. You can then do something like this:

sudo iw dev wlan1 station dump

or if you want to be specific with respect to the peer (in case of
IBSS or Mesh):

sudo iw dev wlan1 station get <peer-MAC-address>

In the case of a STA the above <peer-MAC-address> would be the MAC
address of your AP.

I've updated iw documentation on the wiki with this now.

To use any of this you will also need to upgrade to the bleeding edge
wireless drivers on the wireless-testing git tree as this did not make
it in to 2.6.29. You can use compat-wireless for this as well so you
do not have to upgrade your entire kernel and it will just upgrade you
wireless subsystem. I checked and it seems we don't yet properly
communicate this yet but we will correct this.

Your best bet for now it to test throughput by using iperf.

http://wireless.kernel.org/en/users/Documentation/iw (to get iw)
http://wireless.kernel.org/en/developers/Documentation/git-guide (to
use wireless-testing)
http://wireless.kernel.org/en/users/Download (compat-wireless)

Association is fine in 11NAHT40+ mode.

Am assuming this is a message that you have added ?

Anyway, I don't see any problem, but iwconfig doesn't report HT rates.
You can run iperf and see how the throughput is.
