Up until recently I had my ethernet adsl modem connected to a regular airport together with my usb printer and then an airport express (purchased later) to improve my signal in my lounge and to connect my itunes to the hifi. A couple of weeks ago I added another airport express upstairs connecting my old imac directly to it via the ethernet port to give it an internet connection. Although I set up both airport expresses "automatically" I notice that according to the airport management utility they have different setups, does it matter and which should be best? The main differences that I note are -
Wan IP configuration 1 uses DHCP the other says manually
Multicast rate 1 has 1mbps the other 2mbps
