Poor cable connection error message
I have Xfinity internet service. I have the Netgear CAX80 router/modem that I own. This was recommended by Xfinity. I read in the forums that the incoming speed is to fast for the router/modem?...

I put a coax splitter in between the incoming line and the router/modem. This improved the Netgear error, but it made my google mesh network strength reduce in half in the mode in my bedroom. Went from excellent to fair on the Roku wifi measurement.
This is crazy. I took the splitter out. I think I'll replace the TV in the bedroom to see what this does.

Changing the coax cable signal power levels would not effect WiFi operation/signal strength between the modem and wifi devices.
If your using a external WiFi MESH system, then be sure to diable and turn OFF the wifi radios on the CAX80.
