Wifi 11n (5Ghz band) on Ultranote II

[hogfish]

I have the Intel Wireless 7260 chip which supports 11bgn.

I have 11g and 11n working well on 2.4Ghz, and I can get the specified 300 Mb/s under 11n with a 40Hz channel width.
So all of that is excellent.

However I don't seem to be able to get a 5GHz 11n connection at all.
Moreover iw seems to suggest that is not supported:

# iw list
Wiphy phy0
max # scan SSIDs: 20
max scan IEs length: 407 bytes
Coverage class: 0 (up to 0m)
Device supports RSN-IBSS.
Device supports AP-side u-APSD.
Supported Ciphers:
* CCMP (00-0f-ac:4)
* TKIP (00-0f-ac:2)
* WEP40 (00-0f-ac:1)
* WEP104 (00-0f-ac:5)
* CMAC (00-0f-ac:6)
* WPI-SMS4 (00-14-72:1)
Available Antennas: TX 0 RX 0

Where is the other band and channels 36,40,44 and 48?

This is using the iwlwifi driver and the 11n_disable parameter is zero:

# cat /sys/module/iwlwifi/parameters/11n_disable
0

Has anyone got 11n running onn 5GHz? Any ideas?

Having looked again at the specs, maybe it is simply that the Clevo doesn't support 5GHz? Maybe because it is tricky to fit 5Ghz antennas into the case?
