Good day, I have been battling an issue lately which I have seen others battling. Here's the situation. I have four Google Mesh Pro 6E points. The primary is connected directly to my AT&T gigabit router, and then sends wired internet to a Netgear 20port UNMANAGED gigabit switch. From this switch, it then is sent to my kitchen Mesh point, and a second switch on the opposite end of my house by cat6 wired connection. On the second identical Netgear 20port UNMANAGED switch, it splits off to two additional points. One is in my basement (I am in a split level property), and the other goes to one of my kids bedrooms - both wired backhaul.
This set up has worked flawlessly for months. I get ~800mbps over WiFi to my laptop in any given location of the house. However, recently for no particular reason my 'Gameroom WiFi' point has been rolling back to 'Wireless' backhaul whenever I turn on ANY device on the network. I can actually replicate this. My 85" Roku TV is in the living room on the other end of the house and connected via Wired ethernet to Switch1. However, as soon as I power on the TV it causes Gameroom WiFi to revert to 'Wireless' backhaul. Doesn't even have to be my TV either. My wife is able to trigger the same behavior. Our bedroom is located directly above the 'Gameroom WiFi' point, and if she turns on her laptop it causes the same reversion to 'Wireless' backhaul.
You'd think this wasn't a problem, however it effectively kills my entire home network for 10or20mins until it re-establishes as 'Wired' backhaul. I have NO idea why this keeps happening. There is good spacing between all points, all the ethernet wiring is perfect and I have already replaced it. I have reset all points to factory settings at least twice. I am not Double NAT, I have tried it without my PiHole on the network at all and in a factory configuration. Absolutely nothing changes the behavior. I should add, that Gameroom WiFi and Ellie's Bedroom WiFi are connected to the same network switch and the only point that seems to ever be affected is 'Gameroom WiFi'. However, I have seen it turn into a domino effect where if it doesn't establish 'Wired' backhaul again right away, it can cause both 'Kitchen WiFi' and 'Ellie's Bedroom' to revert to Wireless backhaul until it stablizes and switches back to Wired. This is incredibly annoying. If all of my points are hardwired with cat6 and solidly connected, why in the hell do they keep trying to go to an inferior wireless connection?
I need a way to prefer/force wired backhaul if possible, though being as limited as the Google system is I doubt that will happen.
