A coupla networking questions: How much will an 802.11g Airport Extreme slow down an 802.11n network? II have an iBookG4 that I want to use on the network. I can put it on its own ethernet cable direct from the router but obviously would be more convenient not to. My question is, can i use it via wi-fi on a 802.11n network without slowing down the entire network? Is my router slowing down my network? I have a Linksys BEFSR41 (v.2) router standing between my broadband modem and my Time Capsule. How much difference would I see if I were to remove the Linksys router and use the TC as the router?
