I don't know how it is for DSL, but if you have cable, the router will be hooked up to a router. You don't need to have it connected directly to a computer for it to function. When you set it up, I would suggest hooking it up to the router directly with a cord (it will come with one) and set it up with that. I just suggest it because it will be a bit easier and quicker, as the laptop won't have to continuously connect to the router wirelessly.
