I had problems upgrading via the website as it kept on saying it couldnt detect the MAC address. Rang up CS who tried to put it through and didnt work. Was then told to phone SACM console support (that right?) and they said they couldnt do it and it was not recommended to do so as the modem would most likely go into pre-reg mode meaning no connection as NTL are having numerous upgrade problems!!
Anyway, decided to move my computer to where the modem is, and try the website without going through the wireless router, i.e. direct via ethernet.
Worked a treat, and within 2mins was up and running on 2mb.
Sorted.
