Hi BasilDV While speaking with a TPG technical support person, I was asked what the voltage and amperage ratings are for the power adapter used for the router. I immediately saw the light. I remembered when the TPG technician (or their sub-contractor) came to install the NBN router, he used the existing power adapter cable that was already there which had been used to power the Huawei ADSL router (also supplied by TPG) prior to the NBN switchover. Sure enough the power rating of this adapter is 12V/0.5A, whereas the new router Archer VR1600v requires 12V/2.0A. That is, my NBN router has been underpowered ever since the NBN switchover. I replaced this old adapter cable with the proper one (2 days ago) and I ran a few tests, and now I'm happy to say those dropout issues are all gone. I never imagined this sort of basic technical oversight – it goes to show TPG has some training issues. Hope this may help those who might have the same issues as I did.
