Getting PSP connected to the internet.

Hiya,

I am having problems setting up my wireless network card so i can use my PSP on the net or for gaming. Is there a kind soul out there who would help me out, i must warn you i know nothing about networking at all. I bought a D-Link DWL-G122 to help me do this but i just cant get it to work!!!

Simon

Edit:- Having searched the net i am even more confused and now am not even sure if i have bought the right wireless network thingy!!! Someone please help me out getting desperate now!!!
