I've got a D-Link DIR-655 router and a laptop with a Intel WiFi Link 5100 network card.
I'm running Ubuntu 11.4 x64 -
Linux fraekkert 2.6.38-11-generic #48-Ubuntu SMP Fri Jul 29 19:02:55 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
I've configured the router to allow both wireless g and n, and another laptop is connecting over n, but this laptop wont.
I remember that wireless N were temporarily disabled when Natty came out, but I can't figure out if anything have happened since then, so I guess the memory leak must've been resolved by now.
This is the output from

And the output from

The interface is working, but only in g-mode. If I turn my access point to n-only, I can't connect to it.
