Too bad this guy beat you to it:
http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg2363366.html
You could have submitted a bug report! :(
But actually, this has been fixed in the Debian 0.2-5 kernel as part of
64bit integration bug. Ubuntu just needs is to sync from Debian. So it
should be part of the next slew of updates.
# apt-get update && upgrade
(When they finally do get it over from Debian).
At most it will be 2 months to appear in the newer version, but google
often to see status.
I doubt that this is hardware related so don't think you will fix it
with a new Wireless card (although that WEP is ____!)
Thanks,
