Yoga 720 and Thunderbolt 3 Dock Gen 2 - Network Port not working

2019-11-15, 9:26 AM

I plugged my new ThinkPad Thunderbolt 3 Workstation Dock/Thunderbolt 3 Dock Gen 2 - Type 40AN into the USB C Thunderbolt port in my Yoga 720.

 

The theory being I could run all my related devices off the dock.  I was able to connect Monitors but little else.

 

  • I cant get the Ethernet to work. It wont identify the LAN.
  • I cant get any of the USB ports to drive a wireless mouse and keyboard

 

To get the network and wireless mouse working I had to plug an old cheap dock.  The aim was to replace the extra docks, but the new docking station does not seem to support either wireless mouse/keyboard or the network port.

 

Is there a configuration I am missing. The docking station has a good number of USB 3.x ports and a network port.

 

  • Should I be able to drive wireless mouse/keyboard of one of the USB 3 ports
  • Should the network / ethernet port work

Hi ,

 

Based on the documentation, the docking station is not compatible with your device as shown on https://support.lenovo.com/us/en/solutions/pd500265, that's why you're having issues with it. A lot of people were able to get it to work even on other models but, not all features because of the compatibility of it.

 

You can review this link from our fellow members https://forums.lenovo.com/t5/Lenovo-Yoga-Series-Notebooks/Yoga-720-dock-compatibility/td-p/3684149/page/2.

 

I hope this helps.

 

Jeremy
