If I was supposed to do something in order for Ubuntu to see my network then it could have been working. But if it was supposed to see my network with any intervention on my part then I would have to say that it wasn't working.
Tried to install wicd and I get the following error.
http://archive.ubuntu.com/ubuntu/dists/hardy/universe/binary-lpia/Packages.gz 404 Not Found.

Anyway, it's possible that Network Manager, the default connection manager in Ubuntu, doesn't like your router for some reason--especially if you're using a weird WEP key (i.e. an ASCII key instead of normal HEX). In that case, it may help to install wicd by typing:
echo 'deb http://apt.wicd.net hardy extras' | sudo tee -a /etc/apt/sources.list
wget -q http://apt.wicd.net/wicd.gpg -O- | sudo apt-key add -
sudo apt-get update
sudo apt-get install wicd
Then launch wicd from the Applications>Internet menu. Do you have better luck connecting to your encrypted network then?
N.B.: installing wicd will require that you install Network Manager because they conflict. If you want NM back later for any reason, just type 'sudo apt-get install network-manager-gnome'. If wicd doesn't help, we can look at some other things if you post the output of:
lshw -C Network
dmesg | grep -e ndis -e wlan
lspci -nn
But really on a machine with Ubuntu preinstalled, I'd be sad if it came to hacking in the command line to get the wireless working!
