LAN Problems with HP Envy x360 and HP Thunderbolt Dock 120W G2

[IGMK]

Hello HP Support-Team,

we've got Problems with the LAN Connection on four HP Envy x360 with HP Thunderbolt Dock 120W G2. The LAN connection breaks in irregular intervals and switches to WLAN. We can fix the error when we unplug the dock from notebook and  reconnect. After a while the error occurs again. The Thunderbolt Dock has the latest firmware updates, the Notebook too.

Does anybody have an idea how to fix these error?

thx, Chris

Hi @IGMK

Welcome to the HP Support Community. Thanks for bringing this to our notice.

I see that you are facing LAN connection-related issues on your system. Do not worry, we are here to fix it.

May I know from when are you facing this issue?

Did you make any hardware or software-related changes to it?

Please check that the Thunderbolt device has been authorized and set to always be connected.

1. Right click the Thunderbolt icon on the system tray.

2. Select Approve Attached Devices.
3. Click on the port in which the Thunderbolt device is connected. 
4. The Approve Thunderbolt Devices dialog box should now appear and you will be able to approve your Thunderbolt dock.

Hello Nirvana 95,

thanks for your help. These Issues are since two weeks i think and on 4 devices. All devices are the same Model and the same Dock. No changes done on the system. Only Windows Updates.

I can't open your Link...

Thanks, chris

Hello, we've checked it but there is no Drop Down Menue to activate always on function...
