Hello all,   Just switched my old nbn 50 to unlimited superfast plan, and wondering what to do next to optimize the internet speed, here's my situation:   1. I'm using Archer VR1600v modem router that TPG provided to me. 2. I'm using EERO mesh and wifi extender (3 in total) to extend my wifi signal. 3. The modem router was installed upstairs, I'm using my mac downstairs and the speet test only showing 90 mbps max, after many tries, same or worse result (between 68mbps - 90mbps) is this normal? 4. I'm living in a large house with walls and many rooms, having really bad phone receiptions too (normally can't even making phone calls. Have to go to front/back yard or using wifi calling function from my phone)   So guys, is there any chance to improve my interent speed up to 200ish mbps both upstairs and downstiars while in wifi connection? (Haven't had chance to try out ethernet connection as it's too far away from my computer to modem router) Do i need to buy a new set of wifi extenders? (some posts and threads states eero may interrupt superfaster connection? Please help me guys and thank you so much in advance. ... View more
