What's up all? Anyways heres the deal.. I'm not too computer savvy but I purchased a macbook today and im interested in using the wireless networking. I have a dell dimension desktop hooked up to the internet with a comcast modem. I just wanted to confirm that what I need is called a router? But heres what im looking to do, im gonna throw this desktop away so I dont need internet on here or link em together or anything like that, I just want wireless internet on the macbook and thats it, no other computers. So would any ol router do the trick? Do I still need the modem?.. thanks..
