How do these work? Maybe not the right question. From what i've read this is not what I want. I will probably have cable or DSL installed next week. My girlfriend has a lap top. I have a cable modem, and a router. I am looking for a cheap inexpensive way to make my network wireless for her. Is there some sort of something that I can connect to my router to make it have a wireless signal? I guess I couldbuy a wireless router, and card for my desktop, but I think its spending money I dont have to. The modem will have to sit in another room than my computer and I have 100 feet of Cat 5. So if I could not spend the extra money, I would enjoy that.
