The Setup I have a first generation Time Capsule (wireless N) and an original Airport Express (wireless G). I have an tv (wireless N) and an iPhone (wireless G) My main Mac is a new MacBook Pro 17" (wireless N) and a first edition MBP 15" (g) The Request I want to be able to setup a network (or two) that will allow my MBP 17" and tv to take advantage of the N network offered by the Time Capsule but also allow my iPhone, which doesn't support N to still be able to log on to the network. ------------------------ The Solution 1) DSL modem/router (g) wifi name: DSL WiFi 2) Time Capsule (n) wifi name: TimeCapsule - Connected to DSL modem via Ethernet - Connection Sharing: (OFF) Bridge - set to "wireless n only 5Ghz" 3) Airport Express wirelessly joining DSL WiFi MBP (n) successfully connected to Time Capsule tv (n) successfully connected to Time Capsule iPhone (g) successfully connected to DSL Wifi All 3 are living on one happy network. Success! ...so essentially, you can achieve what is offered with the new Airport Extreme by connecting a g router via ethernet to your first generation Time Capsule/Airport Extreme. The result is a much faster connection between tv and MBP, a noticeably quicker TimeMachine update (using "n"), the distance benefits of Wireless N for my MBP (I can now sit in the courtyard of my building, 14 stories down and pick up my network) all the while still allowing my iPhone to connect to the networking without slowing down the "wireless n" devices.
