Kernel: git tag v3.2 

After modprobe:
Detected Intel(R) WiFi Link 5100 AGN, REV=0x54

If have an AP with openwrt configured to work with 802.11g+n, HT40+.
A different Laptop with Windows installed connects with 150Mb/s

The maximum bitrate for the aforementioned Intel card however is displayed by
iwconfig to be 54 Mb/s which seems to be confirmed by the actual transfer
rates.
The connection is being established by wpa_supplicant 0.7.3.

I tried researching this problem but did not really find it documented. Is this
a known issue or can I provide further information for debugging? 

Many thanks,
John

PS: please include me in the reply.

This was not a bug.
I had to search for ages however to find out about the fact that HT40 only
works with WPA2 and not with WPA. ;-)
