I have an old 802.11g Airport Extreme and a new 802.11n Airport Extreme. Can I set up both of these wireless routers in my home so that my iMac G5 and iPhone (and maybe some friend's computers when they come over) work with the old 802.11g router, while my MacBook and AppleTV take full advantage of the 802.11n speeds of the new Airport Extreme? If so, how would I accomplish that? Will I still be able to transfer files wirelessly between all of the computers? I already tried searching for answers, but was not able to find any related posts. Hardwiring the iMac G5 is not an option (and why is the iPhone not 802.11n). Thanks in advance.
