I've just switched from telstra to tpg and have discovered a few problems with the wi-fi range of the tpg modem being terrible and also I have some devices that require a specialist to come in and reconfigure to work with new TPG router wi-fi network.
As such, I was trying to connect my old telstra modem to the tpg modem using the LAN ports and that I could then continue using the wi-fi network of my old modem. So the plug and play approach hasn't worked. Any advice?
Welcome to the community!
If you wish to use your old modem from Telstra you will have to configure it manually.
I went ahead and tried to use your community details to pull up your account unfortunately no match.
The steps of how to configure a modem/router will depend on its manufacturer.
We posted an article about the general setup of ADSL2+ connection.
You can use this a reference to configure your 3rd party modem/router.
