So I live in a dorm and my friend is able to get wireless internet from his room; however, the signal does not reach my room. So I was wondering how I can extend this signal. I have a Linksys WRT54G router and was hoping someone knew how to set up an access point or whatever will work. My friend has an iMac and I am planning on using my iBook. Can anyone give me directions on how to do this (step by step would be a real help as well).
