[ath9k-devel] not getting 11n rates

[Brian <bnc@netspeed.com.au>]

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.
