Just try to install some more recent wifi kernel modules. - They can come from Ubuntu repositories if you enable the backport repository on your system first.

If you are on Maverick install linux-backports-modules-wireless-maverick-generic. If you are on Natty install linux-backports-modules-cw-2.6.39-natty-generic.
