The first time each PC (or router) connects to the cable modem port of a digital TV set top box (STB) on the NTL cable network, then (having re-booted the STB) you should launch a web browser (which must have JavaScript enabled) and attempt to connect to any simple web site (one which does not have any "/" characters in its URL). You will be redirected to a special registration site for customer PC MAC addresses: if not, try sending the browser to start.ntl. Follow the instructions on the display, and enter a unique name by which this PC will be known to this STB.

It is necessary to repeat this procedure if you connect to the STB another PC (or router) which has never previously been registered with this STB. Once a PC (or router) has been registered with the STB, you only need to re-boot the STB when swapping to it.

If the device you have just connected to the STB is a router, then you should perform the registration procedure via a web browser in one of the LAN clients of the router, although it will be the MAC address of the WAN port of the router that you will be registering, not that of the PC running the browser. When you have completed the MAC registration page (or you are asked to close the browser and restart), restart the router (or make it request a new DHCP lease), not the PC.

This process of registering the client MAC address is quite separate from the registration of the cable modem HFC MAC address with the ISP.

Note that the MAC registration screen is only available to devices whose MAC address has not been previously registered. Once the MAC address has been registered, it is never possible to get back to the MAC registration screen. The site start.ntl does not actually exist.
