Connecting Xbox 360 to wireless router

[natalie_1982]

I am trying to set up an Xbox 360 to play via a wireless router. We got the router set up fine (Belkin G+ MIMO) and cann internet via the pc, but when we have tried to set up the 360 to get Xbox Live (which we were previously getting fine via ethernet cable) it says we need a WEP key. I realise I can only get the WEP key via accessing the router at 192.168.2.1 but IE won't let me view the page. I have googled myself stupid this afternoon trying to find a solution and have tried manually putting the IP, gateway and subnet masks into 360, I have restared everything and done it from scratch, I have reset the security settings in case that is what is not allowing me to view the router page, and have tried to connect to it without internet connection but still no joy.

I even phoned Belkin support but got in a strop and hung up when, after four attempts, the guy still couldn't understand me reading back my phone number. I am going to throw it through a window soon. Any suggestions would be greatly appreciated. Thanks for your help.
