Extend DSL router?
I just got Frontier DSL internet and it comes with a Netgear 7550 modem & wireless router. I would like to use my Airport Extreme to extend the wifi range to the front of my house and also hook up my Airport Express to print wirelessly and play music. How can I do this? I know nothing about networking. Thank you!
