MS Teams and network drops

So I keep having an issue where people are losing network connection while on teams meeting while using a dock. We have Lenovo USB-C docks, but when you are connected to a teams meeting with a network cable plugged into the dock. It drops the meeting, it could be 5 mins into the meeting, 20 mins into the meeting. I cannot find a connection to the length of time it gives you online before you drop. 

It only happens to you if you have a USB-C Lenovo Dock, plugged into a Lenovo laptop, with a network cable plugged into it. If you pulled the cable and work off wifi it NEVER has a problem. 

I have done dock driver updates, dock firmware update. 

Any ideas? has anyone else had this problem?

    We did tests again. We are pretty sure that this ethernet port in usb-c DOCK is getting overheat and after that issue occurs. Port is getting down sometimes after 20 or 40 minutes of Teams call. Most cases when camera is on and port is strong utilized- copying big files on LAN in that time. That was conditions of test environment....

    Regards!

    I think there has been some progress with this

    Lenovo Vantage is offering the update:

    Generic DisplayLink Driver for USB Docks and Adapters (Windows 10 Version 1607 or Later) - 10 [32,64]

    • 10.0.237.0

    This includes a new Realtek Driver (I can't recall the version number, but I remember that device manager stated it was released 31st October 2020). One of my staff members has been in all day teams meetings with the ethernet plugged into the dock without issue! But alas, another member of staff has the same, and they are still experiencing issues

    Upon looking at this thread: rtump64x64.sys bluescreen on X1 Yoga Gen 4 attached to ThinkPad Thunderbolt 3 Dock - Type 40AC-English Community (lenovo.com) - apart from the BSODs, there seems to be an even newer version of the Realtek driver available in this thread for the Lenovo Docks.

    I haven't been able to do any testing yet though (for either driver)
