Hi,
I'm using compat-wireless-2008-08-06.tar.bz2 on Ubuntu Hardy (kernel
2.6.24) for my intel 4965agn card in order to connect using 802.11n to
my router (TL-WR841N from TP-LINK).
Unfortunately, I'm only able to connect in 802.11g mode under Linux :
$ iwconfig wlan1

As you can see, no bit rate greater than 54Mbps is detected. I tried
under Windows with latest intel driver and it connects at 130Mbps.
Does the Linux driver support 802.11n? If so, do you have any
suggestion to make this work here? I will be happy to provide any
information you may require.
In dmesg output, I simply get this:
[ 95.465080] wlan1: authenticate with AP 00:1d:0f:33:7e:ec
[ 95.467416] wlan1: authenticated

status=0 aid=1)
[ 95.471496] wlan1: associated
[ 95.471533] wlan1 (WE) : Wireless Event too big (314)
Best regards,
Chris.
