I just hooked up a new wifi router from my ISP..I used apple extreme for my wireless before this new router. My question is..can I use my apple extreme in another part of my house to hook up my Xbox 360 to the internet without the use of a ethernet cable attached to the router..I would wire the 360 to the apple extreme and no wires to the router..Would that work?? I also have an apple express..would that do what I'm hoping. I'm hoping that I could use airport utility and join apple extreme or apple express to my new network..I think?? Any help is appreciated. thanks
