Hi, my gf just gave me an iPod. I need a wifi set up so I could use it. I've never had a router, currently my computer is connected to cable. I'm also hoping to get a Mac book pro sometime later on when the money is ready..... For now, I need a basic? Set up for wifi connection and thinking about going to a Walmart or best buy. Can you recommend me what to buy? I know the apple router is expensive ( both old / new models).
