Airport Express (xbox 360)

So, I have a tri-level house where the internet/cable comes through in the basement, which is half-underground and brick wall-ed on the side. In that basement is my home theater system which contains a receiver, a ps3, a 360, an apple TV, and a satellite receiver. This is all networked through my apple airport extreme.

I then learned that my receiver only had wireless capabilities, which meant that I needed the $100 adapter. Instead of purchasing that, I bought an Airport Express (2011) (comes tomorrow), which I plan on connecting to my extreme and running a short ethernet cable from the express and to the receiver.

Now, caddy corner, and one level up from that room is my office (30ft away; 3/4 signal), which contains my iMac and an old 360 that I recently refurbished and plan on plugging into the monitor. The 360 has no wireless adapter. Can I use my express as an adapter for my 360 (using the ethernet port), and can it run as a repeater for my iMac in that same mode?

I searched the forums, but couldn't find this exact question. Any help would be greatly appreciated.

I don't believe you can extend and use the ethernet.

My understanding is that the Ethernet will only work in Join mode when you want it to connect to another device.

This is how I have mine set up.

I tried getting this set up to work on my 360, and separately with a Windows machine. I'm not extremely versed in networking, so I have no idea what I'm missing. The main settings I've interchaned are join vs extend network...bridge (on vs off).

Anyone have any advice? I can't find anything relevant via google.

All you must do is tell it to join an existing network, then I believe there is a setting that enables the ethernet connection.

Just plug the XBox into the ethernet port and it should connect right up.

I recall it taking approximately 30 seconds from start to finish to get it set up.

I didn't see the setting you were talking about, as the Ethernet still isn't working. I can see the Express on my network, but it's not passing internet through the ethernet cable.

Is there a setting I need to change in the extreme and/or modem? I'm feeling pretty inept, here.
