I'm considering getting the new AirPort Extreme for the sake of AppleTV, but I have a Wii and a Core Duo Macbook Pro. As such, my understanding is that those two things on the AirPort Extreme's signal will degrade the n speed. 1) Is that right? 2) If so, can I still get it and affiliate it with AppleTV and leave my old Linksys router up to provide signal to the Wii and notebook? If so, how? Thanks for the help.
