1. Get your modem configured with your amiga so you are getting a tempory ip adress (if you have never registered before, your ip is locked onto something that ends with anything higher than 248.
ie. 81.xxx.xxx.252 is tempory NTL ip.
2. Open web browser.
3. Type in adress bar 62.253.162.131 - This is NTL's reg page, follow through here and you will not even need to call tech support. Remember, cable modems can only go on this page when they have a tempory ip adress,, ie the MAC isnt registered with us. You register the modem with you, not the computer. Then you should be ok to go! Any questions, just ask :-)
