Have purchased an Xbox360 and added the network wireless adaptor to be able to use Xbox live. The adaptor shows a constant red light on. The system to which we are trying to connect has a Belkin ADSL router. With this we have a desptop PC connected by wire and 2 notebooks each connected with a wireless network card. All 3 are running fine. However the Xbox will not connect. In settings it seems to see the wireless router but will not connect to it. Help desk for Xbox tried a number of system settings but ended up saying that it must be the router that is causing the the problem. The Belkin customer service say that as the router is working fine with our notebooks the problem must be with the Xbox. Round and round the mulberry bush comes to mind. Has anyone any experience of a problem such as this?

does Live work when the xbox is wired to the router directly?
have you tried disabling the built-in wireless on one of your notebooks and using the usb adapter? if your notebook won't get on the internet with the usb adapter, the issue is with the adapter. if the notebook will get on the internet, then the issue is with your xbox. if the issue seems to be with your xbox, try setting a static ip on the xbox and see if it works. if that doesn't work, change the dns server to an external source such as 4.2.2.2 make sure the default gateway points to the ip of your router.
