Comment 38 for bug 420678

@chielchiel:
No I think not. I am using 2.6.32-23 + the backports package and 2.4 and 5 GHz 802.11n both work. However the iwlagn driver has never been very stable when I used various versions during the past 18 months. When one bug is fixed another one emerges (e.g. Bug #352228). Also my Ubuntu now sometimes crashes when there is an unencrypted AP in reach (could not track this down yet).

Why am I still using Intel wifi if it is so bad?
1. My thinkpad has a BIOS check that only permits using Intel cards so I would have to patch my BIOS to switch.
2. There is not a big range of 5 GHz capable cards for mini pcie to begin with.
3. Other drivers are even worse.

I hope I could help you. :)
