authenticating a modem



Sorry for what might be a potentially silly question.


I have had ADSL connected at my property for years, and today it was changed over to NBN.


It is not working. 


I am using the same modem in which I had for my ADSL. It is not new, nor is this a new connection or new property. The modem is a techinicolour TG797 n V3.


The techician has said that he believes the reason why it is not working is because I need to have the modem authenticated by telstra?? 


I have been to the gateway page and for the life of me - i have no idea of what I am meant to be looking at? It says 'your internet connection is down'.


Can anyone assist at all?


Thanks in advance

Re: authenticating a modem

If you are on an FTTN service (one that plugs in to a phone socket the same way ADSL did), then it won't work as that modem doesn't work on VDSL (FTTN). You need a new modem.


Give 1800 834 273 a call as they should have provided you with a compatible modem.

Never be afraid to back yourself when trying new things, just always make sure you have 3 escape routes if things go wrong.

Awesome - thank you! I will get in touch


All telstra sent me was a grey cord. Should have mentioned that above.


Thank you again. I will stop trying to work out what my gateway is doing, or not doing now Smiley Happy
