Hi,

I hope you can help, I am having problems getting N with new Dual band

While I'm not certain about your AP or the 7260 driver, I believe 
802.11n technically requires WPA2 encryption.  Try turning that on and 
testing again.

This is true, but also Matt is using 'iwconfig', which does not support
anything N-related because it uses the older WEXT kernel API.  It simply
won't show 802.11n bitrates, nor will it show encryption details for
WPA.

Matt should be using 'iw' instead, with:

iw dev wlan0 info
iw dev wlan0 link

802.11n HT prevents WPA:

I do not see however that using no encryption is prevented by the standard...

Hi,

I'm using WPA2/AES and i have other devices connected to the AP using
N, I can't go open as i am resident on a school campus.

Can you tell me if it is possible to get N with this card on linux, or
should i wait for a newer firmware or something?

thanks

then 11n *SHOULD* be possible.  Perhaps 11n is disabled with a module 
parameter by your distribution?

The output of:
   dmesg | grep iwl

might provide some insight(I see: "iwlwifi 0000:03:00.0 wlan0: disabling 
HT/VHT due to WEP/TKIP use" on my system connecting to a WPA1 AP.

The output of:
   egrep -rsn 11n /etc/mod*

might help determine if the 11n_disable kernel parameter is set by your 
distribution.

That should be fixed with latest code and the firmware that is not
released yet...
