Since Telewest does not use authentication, it can be a bit puzzling if you are going to share your broadband internet connection via a Router. I will be using a LinkSys WRT54GS as an example…
Before you do that, it is recommend doing the following…
- Turn off your modem and your Router for about 5 minutes so your PC MAC lease will expire so you can use your Router’s MAC
- If you are having MAC address issue, then you can get your Network Card’s MAC Address by going to
Start => type CMD type ipconfig /all
Write it down, login to the router and use the MAC Address Clone Feature. It’s a 12 Digit code, looks something like this 00-04-5B-89-21-7F
If a cable provider does not use Authentication method, the only way to make your router talk to the modem is via Automatic Configuration – DHCP.
It is also possible to do it via Static IP, BUT if you are on a dynamic IP, then the internet connection will not work when your ISP renews your IP.
If you are on a Static IP and the DNS / Default gateway does not change, then you can hook your modem directly to the PC, go to
Start => type CMD type ipconfig /all
Write down the values, and enter it in the Static IP setting.
This is how it is done if you are on a Dynamic IP.
Turn off your Modem, Reset your Router, and connect your modem and your PC to your router. Then select Automatic Configuration – DHCP Setting.
That’s it, with a bit of luck, you should have an active internet connection via the Router!
