Use LTE with LAN at the same time

Question

Good day,

I want to be connected to the internet with the LTE modum and at the same time connected via a network adapter to the machine at the customer for commissioning.

As soon as I connect the network adapter the connection changes from LTE to LAN and the internet access is gone.

I have already assigned static IP addresses to the network adapter and left the gateway field empty.
If I then go to Windows 10 on Network Status and under Properties on Ethernet (not via the adapter motion) then there is directly "IP assignment Automaitsch (DHCP)" which I can only change to manual when I enter a gateway.
The metric I have already also adjusted LTE < network adapter, unfortunately also no change.
I deactivated the network adapter and reactivated it after establishing the connection via LTE. But also there no change.
In the registry editor "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WcmSvc\Local" added the D-word "fMinimizeConnections" with the value 0 and restarted. Unfortunately no change either.

Answer

Hi.

There may be some setting in the BIOS that does not allow the simultaneous use of the LAN network and the Cellular network. Contact your pc manufacturer's support.
