Well, if the cable still works then you need to have someone look at that 360. I haven’t heard of this problem before, but it seems that the problem would be the system itself.
Why does my xbox 360 not connect to the internet?
I am having problems connecting to my network with my xbox 360. The other 3 computers in my house have no problems connecting to the internet. The cable I am using for the xbox 360 to connect it to the modem works with the computer, but not the xbox 360. It worked with the xbox 360 a few months ago, though. If someone could help me, It would be very much appreciated.

I would recommendd if you have wireless broadband that you invest in the WIRELESS adaptor. This enables you to play wirelesly over Xbox LIVE. This can be costly depending on your region but it’s a great investment and easy to set up. It usually asks for a WEP code when installing, just like Nintendo WFC for Wii & DS.

Here are a couple things to try.
1. Make sure your router is pulling an IP Address for your Xbox. Go to your xbox dashboard and go to Network Settings > Test Connection. If the IP Address comes up ad 0.0.0.0, that’s where the problem is. Unplug your router for 30 seconds then plug it back in. If it still doesnt work, depending on your type of router, there might be a switch on the back to Reassign IP Addresses. Try that and I hope this works
