Hi @nodleh72 ,
Welcome to the community!
We have an existing thread about this, please see the link below.
Let me know how it will go and should you require further assistance.
I’m trying to set up my new Google Nest Wifi router to run off the HG659 modem provided by TPG as part of our plan. Had a lot of trouble getting the Google Nest to connect to the internet via the modem. I’ve read that setting it to ‘bridging mode’ is required but I’ve had no luck enabling that either.
