We've been with Telstra ADSL2+ for years, and recently we were told to migrate to NBN within the next few months.
I first contacted TPG on 13/1/21. Everything seemed to go well and modem+router turned up on 14/1. Late on 14/1 we got the first "Plug in your modem" message. I thought that was great service so I plugged in the modem+router, left it for several hours with no connection, then called support & the support guy said the connection wasn't ready yet but would be the next day. Plugged in ADSL and got it working again.
Next day, same thing - plugged in NBN modem+router, left it for about an hour, then called and found the connection wasn't ready yet.
A few days later, I got a second "Plug in your modem" message - plugged NBN modem+router in that night, left it overnight and didn't get a connection. Unplugged NBN, plugged in ADSL again and got back to work.
On 22/1 I got a "TPG is unable to activate your NBN service as your modem is not connected". Aha, a different message, so looks like progress! Plugged NBN modem+router overnight, again no connection the next morning. Familiar routine - unplugged NBN modem, plugged in ADSL again and ADSL works fine.
Today (24/1) I've plugged in NBN modem+router approx 1 hour ago, listened to it switching away, and still no connection.
Each time - the behaviour has been the same. On the NBN modem, power is solid blue, link+DSL is flashing blue, LAN light is off. There's no ADSL filter in the line, and the cable sent by TPG to connect NBN modem to phone jack works fine on the ADSL modem.
