Setting up Internet Connection Sharing with Xbox 360

[cd216513]

I'm trying to set up my Xbox 360 for online play without having to buy the wireless adapter, because it's expensive and I think I might already have the materials to get it up and running. I have a wireless router that I got from a friend, but my ISP won't let me switch it out with the wired router I currently use. I was going to connect the wireless router to my 360 via Ethernet cable, and put the router in client mode (I put the micro DD-WRT vintage firmware on it) to work as a Ethernet bridge. Then, I was going to connect that via wireless to my desktop on the side of my house that has the router. First of all, could someone tell me if it's even possible to set this up and share the connection, and if it is possible, what steps do I take to set it up? The router is Linksys wrt54g v.3 and my desktop will have wireless via a Linksys wireless g PCI card that a friend is giving me. I'm really hoping that I can get it to work... Any help would be greatly appreciated!

Does anyone have any thoughts?

Sounds complicated, in theory it should work. Try it. If it doesnt work, just set everything back the way it was. The best way to connect your 360 to the internet is by ethernet cable. You dont get as reliable a connection by wireless.

Alright, thanks so much for your opinion! Would you happen to know how to connect to an AP with a client router? I've never done it before. I was trying the router out on a desktop that's in the same room as the 360, but I didn't know how to find the other computer. It showed that I was connected to the router through Ethernet, but I wasn't sure how to get the wireless part to connect.

1. Connect the wireless router to the wired router using the procedure below.
2. Bridge the wireless connection with the wired connection to the XBOX in the machine that's connecting wirelessly.

Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
