It's a Broadcom wireless LAN card. Try the following in terminal:
sudo apt-get update
sudo apt-get install bcmwl-kernel-sourceThis should blacklist the non-working device module in '/etc/modprobe.d/blacklist-bcm43.conf' and install the working one. If you are still having problems, have a look at the community help pages for the broadcom devices.
Desktop support for 10.04 LTS runs out in April next year. You might consider 12.04 LTS because the driver module support may be better, and it will be supported until April 2017.
