Hi, I am soon to receive a new airport extreme, which I would like to run a wireless-n network through. However, I also have some wireless-g components (iPhone for one!) which I would like to access the network. I want to do the following: 1) Setup the Airport Extreme as an .n wireless network only 2) Setup my broadband router with a separate .g wireless network This should be fine, the Extreme will be wired to the router for WAN. However, both the router and the Extreme will be housed in a cupboard side by side. Will I suffer interference wise on this? What's the best thing to do? the .g network will be used very minimally, so will I only suffer on the .n network when the .g network is being used? Also - if I want to utilize gigabit on my Extreme, PS3 and ethernet HD - will cat 5e cable suffice, or do I need cat 6? Thanks all.
