Now we have 6 macs in our house hooked up to the internet with some linksys router and hard wires. My dad has a macbook which he hooks up to the wire when he wants to go on the internet. And I just got a touch. I was thinking of getting wifi now so we can use the devices without wires. We would leave the computers hard wired because it is faster but could we just get an airport express and put it somewhere hooked up to the router and it broadcast wirelessly to these two devices. And about how far can it go? our rooms are about 4 rooms away thanks.
