I don't have a degree in wireless technologies, so please bear with me. I have a Time Capsule, Apple TV and two MacBooks. I would like to take advantage of the Time Capsule's setting of "N"--5 ghz. The catch is I also have an iPhone and would like to use it on the network, too. I have an older Netgear "g" router that I could use to set up an additional wireless network. What is the best way to set up two wireless networks as I've described--being sure that they won't interfere with one another? I appreciate any thoughts.
