I've been having issues with speeds on a Nest Wifi network (four pods). The Xfinity modem/router is only being used as a modem, but the speeds when I revert to using the Xfinity router instead of Nest are FAR better than what I'm getting through the Nest devices (the *advertised* speed vs 1/10 of that). Is there throttling I don't know about, or some other limitation in the Nest devices?
I have the same problem with Google mesh 2 pods. I check the Ethernet directly from provider speed test shows exactly what I am paying for 25/5. Check WiFi speed on older TP Link WiFi speeds are 25/5. Remove TP Link and connect Mesh pod 1 with built in router WiFi speed drops to 9/5. The odd thing is over time the Google WiFi will finally speed up to the proper 25/5. If there is a disruption in service from my provider (Nextlink) the speed drops down again.
Sorry for the speed issues you're seeing on your wireless network. I imagine that's quite frustrating. The speed issues you're seeing are not a limitation of the device, so we're probably looking at some issue with the network environment. There's actually a new firmware update coming out soon and it will hopefully get your network working as intended. If you see that update hit and things don't improve, let's look at more options for troubleshooting.
So the update is pushing out now. Everyone will have it before the end of April, but many will see it sooner. You can use the Home app to check what firmware version you have. Go to your router in the device list, tap on it, tap on settings, and check the software version. If you see 14150.43.80 then you have the newest release. If you see a different version, you're still waiting on it the update for now.
