I just purchased a new MacBook laptop and have no idea on how to go about getting wireless internet for it. On my regular iMac I have DSL set up and I want to know what I need to buy in order to have simultaneous internet access to both computers, and also so that both can use the internet at the same time without any conflicting traffic or lagging. In order for my laptop to go wireless, does my desktop iMac have to go wireless, too? I don't know if this provides enough information, but if you could help me out with anything you can tell me that would be wonderful. I have no idea where to start. Thanks.
