Microsoft Teams Kills all Network Connectivity During Calls

Despite having a good WiFi or Ethernet connection, regardless of which network I'm on, if I join a Microsoft Teams call, all network connectivity stops working and teams simultaneously reports poor call quality and no network connectivity. All this while on an active call which I can see and hear. Here's a full description of symptoms.

Every time I connect to a Teams call:

  • Incoming call quality is ok. I can hear and see others.
  • Outgoing call quality is very poor. Others say my voice is breaking up.
  • If I unmute and speak for more than a few seconds, I am booted from the call.
  • If I stay muted I can stay on the call indefinitely.
  • I can share my screen just fine, I don't get kicked from the call.
  • Teams periodically puts up a warning symbol in the call controls reporting poor connectivity.
  • Teams puts up a blue banner stating that I have been disconnected from the internet.
  • (Intermittent) Teams puts up a big overlay on top of the whole app saying I have been disconnected
  • The call continues though all of this, including voice and video.
  • All other network connectivity is broken (e.g.: Browsers cannot load pages, network drives stop working)
  • Text chat features work fine (but not during calls, where they fail to work like all other network activity)

The instant the call ends, all the symptoms stop. I can access network resources again. My wifi connection is fine. I've tested using wired networking and encounter the exact same issue. I've also tried various audio devices and disconnecting all peripherals as longshot solutions. No dice. I don't have anything weird on my system as far as I am aware. Teams works fine on other machines but not on my primary laptop. 

This issue not only makes Microsoft Teams itself nearly unusable, it knocks my whole system offline for the duration of the call, which is incredibly frustrating.

I'm booting into Windows 10 on a 2015 MacBook Pro 13". I have all the latest patches for everything. I've seen two other people here who have what I think is the same issue as mine, but their question threads didn't have any solutions either, and now they're locked.

Does anyone have any idea what could be going wrong? Any solutions? Any more info needed from me about my setup?

    More updates on this, I've been having this problem for a while and just ended up doing Teams calls on a different system

    Today I was on a Zoom screenshare, and the NIC did the exact same thing. I rebooted and I can replicate the issue over and over again

    Hallo Daniel,

    we have the USB-C Dock Gen 2 and I got the information, that the firmware of the dock isn't updated automatically with Thinkvantage or Systemupdate. You have to download and install the firmwareupdate manually. 

    So I did this using this link: https://support.lenovo.com/us/en/downloads/DS539092

    Hallo William,

    yes sure, we already have installed the latest firmware for the modell we have: https://support.lenovo.com/us/de/downloads/ds504448 or. https://pcsupport.lenovo.com/de/de/products/accessory/docks/thinkpad-hybrid-usb-c-with-usb-a-dock/downloads/ds540663

    But not the driver from November., we´ve installed the version before.

    I will test it soon as possible and give feedback, unfortunately after holiday.

    Have a nice christmas (Christkind!)

    Best regads

    Daniel

    Hi Christian,

    I tried, but never got over the "If Teams crashes call Microsoft" issue. But according to my sales rep, there are some firmware updates for the docking itself, which has to be installed manualle (see my posting a few minutes ago). I post back in a few day if it helped.

    William
