Hi,
I have a belkin wireless G router which doesn't work with my ntl broadband it got something to do with changing the USB connetion to ethernet can someone tell me how
Please! Thank you

On your NTL Broadband box there should be a couple of different cable connections.
The normal Cable and power in with a couple of output ones.
One is your USB connection and the other is for Ethernet. Somethimes it is covered by a sticker.
Now this looks like a telephone cable, but is slightly larger.

You'll need an Ethernet cable, freely available and normally supplied with the modem, with which to connect your modem to your router.
The instructions for the Belkin cover what is needed.
