what type of wireless card?

what type of wireless card? Run this please and post the line related to your wireless card:

sudo lspci -nn

The previous 2 versions of Ubuntu worked fine with my wireless, but 10.04 installs the wrong driver for my Broadcom 4312. If your wireless card happens to be a Broadcom 43xx type, I had to do the following:

(1) connect your laptop to a wired connection, then run...
(2) sudo apt-get install bcmwl-kernel-source
(3) sudo reboot

Results of sudo lspci -nn:
