If you lose your network connection while using your monitor's built-in USB LAN adapter, check the following.

 

 

<1. Scenarios>

 

● The network is disconnected while using Zoom app

Update the app to the latest version or join Zoom Meetings from a web browser without using the app.

 

● The network is disconnected when switching the input signal of the monitor

When using the monitor's KVM/USB selection function to share a mouse or keyboard across multiple computers, switching the input signal will cause the USB LAN adapter to be disconnected from the network on computers that are not related to the input signal being displayed. When the input signal is returned, the USB LAN adapter is detected again, and the network is restored. 

This is the intended behavior for KVM/USB selection function. Be careful when switching input signals while downloading or transferring large files. 

 

● The network is disconnected when daisy chaining monitors

Plug the network cable into the monitor that directly connects to the PC. 

In the following figure, unplug the network cable from monitor 2 and plug it into monitor 1.
