Setting up lap top to use WiFi

I have been trying unsucessfully to set up my laptop to get onto WiFi. Is there any places around Oaklands Pk/Glenelg area that can set it up for me or can anyone out there tell me in laymen terms how to do it myself. I will be able to get free WiFi soon when I commence my new employment at Olympic Dam so I want to be able to bring along my laptop to have something to do on lonely nights (eg surf porn
).
FWIW my laptop has built in wireless 802.11a/b/g+BT if those codes make any sense!! I have no idea as still run dial up at home.
