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 have exactly the same problem with all our dockingstations over usb-c

    It happens on Acer, Lenovo laptops and Surface Tablets...

    I tested around 8 different usb-c docks, but after a while the usb-c (mostly some kind of realtek network card) lan disconnect.

    According to the win 10 systemreport ms teams (nothing else was in use) try to set a new/different DNS and then failed and disabled the card... Sometimes it helps to disconnect the dock, sometimes we need to restart. 

    This is a realy big problem and it is more than frustrating... :/

    Plz microsoft fix teams... The program is so often more than buggy... Usb-c prob, login probs, not remembering loginnames etc.

    We have the same issue to report as well. Lenovo Gen 2 Docking Station USB-C. Things we've tried so far with no solution:

    1. Replace Dock
    2. Update dock firmware (if available)
    3. Replace Dock with 230W model
    4. Change realtek driver to a newer one (downloaded from Realtek's website)
    5. Reinstall Teams (Clearing App Data as well)
    6. Replace laptop completely

    New observations:

    1. Users with this issue have the same monitors and plugged in using 1 hdmi cable
    2. Users with this issue report no problem when working from home (no dock)

    I am currently testing a scenario without using HDMI, instead i am using a DVI/DP cable. I noticed an audio source in Device Manager identified as Display Audio Device (HDMI).

    So far so good. With others in this forum dealing with this issue, any of you using HDMI between the monitor(s) and Dock?

    It looks like Lenovo and Realtek are dealing with this.

    A guy on a Spiceworks forum quotes the following transcript after Lenovo left him a Voicemail regarding the issue:

    "

    I'm calling from Lenovo Support in reference to a ticket regarding a P53s having issues connecting to a dock with Teams.  Just wanted to basically give you an update on this that Lenovo Engineering is working currently on a fix for this with Realtek.  Apparently it's an industry-wide issue regarding the Ethernet controllers in docks, and we definitely are looking into it with Realtek to get a fix on this.  We will, once there is a fix available, we will reach back out to you and let you know.

    "

    I have the same issue.

    ThinkPad P53s with Lenovo dock 40AS.

    Network connection stops working at random moments during MS Teams meetings.

    Disconnecting and re-connecting ethernet cable during meeting fixes the issue temporary.

    Issue ONLY appears during MS Teams meetings, but is still present after meeting ends.

    It is the entire network connection that stops working, affecting all applications on the PC.

    I tried updating both dock drivers and dock firmware, but it did not fix the issue.

    Issue does NOT appear when connected over WiFi or PCs own internal ethernet adapter.

    Also issue does not appear when using a USB ethernet adapter.

    My current workaraound:

    Instead I use a StarTech USB to ethernet adaptor connected to the docking station.

    This results in a reliable ethernet conenction through the dock:

    [Laptop] <--USB--> [Dock] <--USB--> [StarTech] <--Ethernet
