hello everybody I'm looking to buy an airport express soon. I was wondering if you can use the Ethernet port on the express to connect an Xbox 360 using a Ethernet cord? I will use the express in conjunction with an airport extreme.
The Express only had one ethernet port, so you use an ethernet cable to connect the Express to your 360.
The software you use to configure the Express is called Airport Utility and it should already be on your Mac.
Is your other wireless router in the house an Airport Express/Extreme/Time Capsule?
I'm not at home now, so I can't pull up my Airport Utility, but instead of going into the Manual Setup, try using the Automatic Setup option. Make sure Airport Utility is talking to your Express, not your Extreme. One of the "join to an existing network" options should be what you're looking for. If you're going to do it manually, you have to jigger around with the WDS options.
