Windows 10: Active Ethernet connection disables Cellular Modem

Folks,


I came across an issue on my Windows 10 Enterprise Build 1803 with Cellular/Ethernet connections.

I have a HP lt4120 Snapdragon X5 LTE installed in my notebook.


I purchased it with the intent to work on the road and to leverage it for ICS.


When I am connected with the LTE modem and plug in a cable to my Ethernet port (Intel I219-LM) it automatically disables my Cellular connection ("Not Connected).





So far I have not found a way to keep both interfaces connected at the same time, for me to configure ICS. How can I get rid of this behavior?


Any inputs are appreciated.

:)

 

Using modems and coax instead of ethernet

I am trying to get rid of my cable ISP, and have secured a cellular modem that is faster and cheaper than my ISP. My rental house has coax throughout, so I was thinking of using modems to connect the upstairs to the downstairs, through the coax.

Is this possible?

4g USB modem---computer with ICS---Ethernet to modem---coax to next modem---Ethernet to network.

 

Data trough 4G mobile broadband connection blocked when ethernet connected

Hi Robert,

It appears that Windows is managing your connection. It only allows you to connect to your mobile broadband connection if you're not connected to either Wi-Fi or Ethernet connection. To work around this behavior, I suggest disabling this feature to allow
you to manually connect to your cellular or mobile connection. Please follow these steps:

1. Navigate to Settings > Network & Internet > Cellular.
2. Uncheck the box for Let Windows manage this connection.
3. Once done, try connecting manually to your mobile broadband while Ethernet is connected and see if it works.

For more information about mobile broadband connection, please check out,
Cellular settings in Windows 10.

Please update this thread with the result so I'll be able to assist you further if needed.

Regards.

 

Cellular/SIM connection not available/disappearing

Hi,

A faulty cellular adapter is one of the possible reasons why the cellular connection is disappearing from the laptop. A disabled adapter in the Network Connections Settings can also be the cause of this issue. We suggest you to enable the cellular connection
in the Network Connections settings. You can follow the steps below:

• Press the Windows key.
• Type View Network Connections.
• Press the Enter key.
• Right-click on the cellular adapter and click Enable.
