Hi there, I've got a half dozen or so Google Wifi access points throughout my house and they work great (most of them them are connected to cat6). The issue is with my backyard office/garage. I laid a subterranean cat6 cable to the office so that I never have to worry about wireless issues on my laptop while Zooming, etc. This also works great: I routinely get between 200 MB and 950 MB internet speeds on my laptop (we have a fiber connection to my house).
HOWEVER, the Google Wifi access point in my backyard office/garage that connects to the cat6 are super unreliable. The best I can get is a 50 MB wifi connection to them over my iPhone, but that connection drops constantly. It's unusable for streaming and wifi calling from my mobile devices, even though the light on the access point rarely indicates it has lost connectivity.
I've spent hours trouble-shooting this. My wired connectivity to the office isn't the issue. If I disconnected the access point from ethernet, the mesh signal to the wifi access points in my house is too weak to be practical. My only theory is that the access point in my office/garage is still somehow holding onto the weak mesh connection with the access points in the house. Any other thoughts? Is there a way around this? I guess one option is to just buy another, non-google wifi access point and create a separate wifi network in the backyard office.
I've got the same issue here. There is in my house a Nest Router and two Wifi Points. In house everything Ok and have 200 MB internet speed. So far so good.
In my garden office i've also a Nest Router who is connected with a cat 6 cable to the Nest Router in my house. Only after installing there is a internet connection, but after that the connection drops... There's only 5mb or even no signal. I think the devices prefers to connect by Wifi / mesh instead of the wired cat 6 cable.
At Google nobody can help me with this problem.
How have you guys connected up this? What exact switch did you use? Managed/smart switches with loop detection functionality, like STP (spanning tree protocol), are known to cause bad performance for wired backhaul.
Here is a diagram showing how wired backhaul should be done:
