Hi David, thanks for your response.    Yes, we have the wifi disabled on the modem/router. Unforunately we don't have any windows computers. However, I am able to see that the signal strength doesn't drop at any of the google nest wifi points when the slow down occurs.    I was just on the phone with TPG and they said I needed to make sure the connection is DHCP or dynamic IP for the google nest router, but you're saying the google router needs to be set to access point mode with DHCP disabled? Are you able to explain why this is the case? Just trying to get my head around it all!    With regards to the speed tests, direct to the modem/router and direct to the google router are both fine. Its purely the google nest wifi points upstairs that have the issue.   With bridge mode, do you know how to do this? I have been trying with no success thus far...     ... View more

The speeds on the modem/router itself are fine, its getting it to work with the google that seems to be the issue, the google router we don't have a problem with, but issues projecting to the other google points over sustained periods of time (which wasn't a problem prior to swapping to TPG) ...

Hi David, thank you for all the questions!   We have a tp-link VX420-G2h model modem/router with VoIP (but we do not have a phone connected), it is version 2.0. Google nest wifi we bought early this year, so I assume it is the latest.    At present, we have tried turning off wifi on the modem router and solely using the google nest router, when connected to the router downstairs (via wifi) we are now getting high speeds (up to 100mbps download and 30 upload). However, the google router is still struggling to connect to our upstairs points. When we unplug and re plug everything it works fine though (upstairs we could get up to 60mbps download and around 20 upload), but it inevitably stops working after a day or two. Prior to turning the wifi off on the modem/router, when this would occur, we couldn't see the upstairs wifi, now we can still see it and connect but the speed drops to insanely slow (can't even actually run a speedtest).    My next step might be to turn the modem into bridge mode? Please let me know if you have any more advice!   ... View more
