MN-740 cannot find wireless network

Archived from groups: microsoft.public.broadbandnet.hardware (More info?)

I have a Belkin Wireless-G DSL/Cable Router
Whenever I try to connect to Xbox Live, it says it cannot be found.

I have tried manually entering my IP, gateway, and subnet, but it still
wont connect.

It worked at one time, but each day the connection became worse and worse.
Until one day, it vanished. I have the lastest firmware installed.

Can anyone help me?

Thanks
