OK, so here is my problem....HELP!

[roccenstein]

Let me describe my setup first.  I have a pc upstairs, and then another one downstairs (both running xp pro sp2) and an xbox 360, also downstairs.  I recently bought a Linksys wrt54g router and a linksys wireless card.  Originally I had the router connected directly to the pc and 360 downstairs by network cables, and then had the wireless card on the pc upstairs.  I decided to change this setup though since the upstairs pc is my primary one and the wireless is a little slower than being directly connected.  SO I moved the router upstairs and then put the wireless card into the pc downstairs, got it all running and no problems, and I just figured I'd get a wirless adapter for the 360 later.  So anyway, short story long, last night I decided to connect the 360 with a network cable so I could download a few demos, but I can't get any connection.  I tried a number of different things, reconnecting using a different port on the router, pushing the little button on the front (though I think that only helps when trying to set up a wireless connection), etc.  The only thing I haven't tried yet is pushing the reset button on the back of the router.  Why is the 360 not detecting the connection when it was connected that way before?  Is it because it was through another pc?  On my router setup screen, it shows the 360, but the connection is not active and it doesn't give me any options other than to view detail.  What can I do to fix this?

I seem to remember having a similar issue with my wireless 360 setup...

Are you running encryption on your wireless network? If you are you will have to enter your encryption key, the long one, not the passphrase used to generate it in your Xbox setup. I would also check  and make sure your MAC is entered into your MAC address filter on your router (if you are using one).

No, I'm not using wireless for the 360, I have it hardwired directly to the router using a 50ft network cable.

My fault, I read the post to fast...

I am not near my xbox360 (at work ), but I would suggest poking around the network settings on it. I remember they are somewhat buried. See if you can delete your current connection and recreate it. There is also a utility on the xbox website where you can do a quick network connect with a USB thumb drive. Though that may or may not be for wireless setup, my memory is foggy on the specifics.

Originally I had the router connected directly to the pc and 360 downstairs by network cables

Is it because it was through another pc?

This is contradictory. If a pc had been used as the gateway for the xbox, then the xbox will have to be reconfigured so that the router is the gateway and DHCP server.

[roccenstein]

Yeah, I may not have worded this right.  What I meant was the 360 and the downstairs pc were first connected directly to the router, but now the router is upstairs and the downstairs one is wireless.  What I meant by that question was would it have messed up the settings to have had it connected in the first place, then disconnected it, then reconnected it after the router was installed with another pc?

If nothing changed except the location, the settings should not have changed. What IP does the xbox have? If it is 169.xxx.xxx.xxx and is set to automatically acquire an IP, sometimes a simple reboot of the router will do the trick. Leave all the machines running, disconnect the router power for about 10 seconds, then reconnect. All the IP's should be reassigned/renewed.

Yeah, after pressing the reset button, that was going to be my next step.  I'll try it tonight when I get home.
