WiFi disconnects when ethernet is plugged in

Hello, we have problem on Windows 10. When we connect ethernet cable, the WiFi automatically disable WiFi adapter. We checked BIOS, properities of adapters, check presence of third party programs and nothing is set wrong to do that. It started doing after Windows 10 update on December 2018. Is it something in registry?

Answer

Hello,

This happens because of higher priority of Ethernet as compared to WiFi. The priority order is Ethernet > WiFi > Cellular. More information provided in this documentation:

 

https://docs.microsoft.com/en-us/windows-hardware/drivers/mobilebroadband/understanding-and-configuring-windows-connection-manager.

Try these steps to use both WiFi and Ethernet as same time:

1. Open Registry Editor.

2. Go to HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\WcmSvc\Local.

3. Create/change the fMinimizeConnections registry DWORD to 0.

4. Close Registry Editor and reboot.

Hope this helps!
