My NBN connection keeps on dropping out every 15 minutes

My NBN FTTC connection keeps dropping out every 15 minutes, I have done the following:

Restarted/Reset the NBN modem a few times

Restarted the Wifi Router(s) a few times

When connection the DSL and the LAN lights both turn OFF on the NBN Modem

Original speed achieved is pretty good = 46Mb/s average.

Still the issue is unresolved and now dropping out every 1 minute now - I doubt it is TPGs fault but the reliability of the NBN setup

Still not serious direction from TPG will cancel account in 3 days and go elsewhere
