Windows 10 Cellular With LAN

Question

I have a system that relies on a cellular connection managed by Windows for internet access. An issue is coming up when a LAN connection is made to some local hardware. When connected locally the PC looses the internet connection, but windows still lists the cell network as connected. I have tried a few fixes including changing the network priority as described in the link below.

Are there any other settings I should be looking at or ways to manage the network? I have the version of Windows 10 at 1803

Answer 1

Windows 10 always prefer ethernet over cellular, even if the ethernet connection has no route to the internet. This behaviour can be modified since update KB4284822 by adding the registry key:

HKLM\Software\Microsoft\WcmSvc\IgnoreNonRoutableEthernet = (DWORD) 0x1
