Main documentation on ath9k+802.11n

[Dennis Borgmann]

Hi linux-wireless list,
hi hostap list!

I am trying to get a 802.11n-network as test running. I want to test the
highest throughput, that I can do with this setup to see, what could be
possible for me.

My setup is a Senao EMP-7605 card and ath9k with a 2.6.32.8-kernel.
Thanks to Jouni Malinen, I am now using the latest snapshot of
hostapd-0.6.10. If I start hostapd, my Lenovo Thinkpad(I think, there is
an Intel card running inside there) can find the network, that I
established with ath9k, but another Senao EMP-7905 with the same setup
as mentioned above won't find the wireless network at all, even during a
scan. If I do an iperf between the Lenovo and the board, that runs the
AP with hostapd, I get throughput rates of about 6 Mbit/s. iwconfig on
the Lenovo shows the bitrate set to "0" - meaning auto.

I cannot find valuable documentation about setting up a wireless-link
with ath9k using 802.11n-capabilities. Is there any hint, that someone
could give me or a webpage that I could be pointed to? I just want to do
some speed-tests, but even the "ht_kapab"-field of hostapd leaves me
without any knowledge, what to put in there...

Any help would be appreciated!

Very kind regards,
Dennis Borgmann

Documentation is not supposed to be device specific, so for hostapd
with 802.11n we currently have:
