I have been reading post after post, and none of them gives enough explicit detail for me to figure this out. I want to create 2 separate networks in my home, one just 802.11n the other 802.11g. The n is for internet and time capsule with my MacBook Pro, the g for my iPhone. I have a Time Capsule, an Airport Express and a DSL modem. Right now I have the DSL modem connected to the TC and it set for 802.11n only @ 5 Ghz. The Airport Express is connected via an ethernet cable to the TC. What settings must I change in the Airport Express "Manual Setup" section to ensure no problems? I have heard of turning of DHCP and something about SSID. I have no idea what those are. I have a static IP address from AT&T. Thanks so much!
