Clueless - Need help adding second laptop to wireless network

Hello. I recently got Virgin broadband installed in my house and bought the Belkin G+ Mimo wireless router so my flatmate and I could use our laptops anywhere in the house. We followed the install procedures as detailed on the Easy Install Wizard program on hers and her wireless now works. I just can't figure out how to make it work on my laptop. Internet works if I plug it in directly to the modem, but I can't seem to make the wireless bits work. My laptop is an Advent K200, if that's important.

This is most likely some very basic error on my part, but I am pretty clueless about networking in general and can't seem to find anything adressing my problem on these boards. If anyone would help, I would be most grateful.

Figured it out myself. Thanks anyway for reading.
