3. Enter 'ipconfig /release'.
4. Disconnect the power supply from your cable modem, for 1 minute. (Whilst your cable modem is effectively powerless, enter 'ipconfig /renew' in the Command Prompt window, WAIT! DO NOT press Enter/OK)
5. Connect the power supply back into your cable modem, and then press Enter/OK on the above command (which was 'ipconfig /renew'), continuously repeat the same command using the UP button on your keypad (saves you manually typing it in).
6. It should hopefully provide you with a new IP. This has always worked for me.
The reason you enter 'ipconfig /renew' at step 4 is so that you don't waste time at step 5 -- If you waste time, there's every possibility that it won't work.
Hope that helps!

This tutorial is designed for those using a cable modem.
1. Connect directly to the cable modem, you must not
connect through a router -- you can connect through a switch, but it's not recommended (reason behind this is that ntl:telewestbusiness customers can have more than one CPE assigned to their modem, and if you have multiple computers or whatever connected to the switch -- it won't work.)
2. So you've connected directly to the modem -- i don't care how, just make sure there is no router involved.
3. Command Prompt ... Run 'ipconfig /release' and remove the power supply from your cable modem -- leave it unplugged for about 2 minutes.
4. This is the tricky bit and where you have to act fast
. Whilst you're plugging the power supply back into the cable modem, you need to run 'ipconfig /release' (the opposite to /renew) ... KEEP
doing it and KEEP
doing it -- even if it says that the IP address is something like 192.168.100.1 -- NO, this is not your router assigning IP's, you haven't connected through it remember? ... this is just the IP local to the cable modem itself.
5. The above (4) doesn't too long, just be patient for a few whilst it connects.
6. Should have a new IP
