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. https://answers.microsoft.com/en-us/msoffice/forum/all/microsoft-teams-always-appears-poor-network/1a9ef89c-e495-4e2c-b108-d5b8702a54a8 https://answers.microsoft.com/en-us/msoffice/forum/all/teams-kills-all-connections/6b9dd383-df31-4bec-957a-41ee478eab3e Does anyone have any idea what could be going wrong? Any solutions? Any more info needed from me about my setup?

Brand new Macbook Pro 13" fully loaded running Catalina 15.15.5 and all networking has been killed on 3 separate occasions while using Teams. Restarted twice the did a renew lease that brought everything back the 3rd time. This needs to be resolved as all of us are more dependent on this as a connection with clients and internal meetings.

Same **** happening here, using Debian10 and wpa supplicant without GUI. I thought it was a problem with the supplicant settings since the thing is usually nuts, but the connection only drops at night during meetings. I left the laptop running a video all Sunday and it didn't drop the connection. The problem is definitely with teams, it drops my connection on both web and desktop versions.

I am getting this issue in both Teams and Outlook. But the issue does not occur on the Web versions of these products. Our servers are on Google Cloud, so we need to connect to GCP VPN, not long after connecting Outlook and Teams will both lose connection, however nothing else does. Internet browsers work fine, and so do streaming apps like Spotify / Sky Go / Prime. It seems to be a Microsoft App issue. I am running MacOS Catalina on a 2019 Mac Pro.

I seem to have found a solution! I had the same problem, with the disconnection of all devices from the router when running MS Teams conferencing. I tried different solutions as above, but finally worked on router level: I changed the automatic channel to a channel with no interference (with radar application on the router). I have had a couple of conferences today, with no disconnection. Hope this works for you too.

Hope this works for you too. @Bobaskh, I think that's not exactly the same scenario as what's been described here - issues described here have more to do with a RealTek Ethernet device, possibly found in a USB or Thunderbolt 3 / USB-C dock, and not so much the router disconnecting. For instance, my laptop is connected via Ethernet to an unmanaged switch, and the switch to the router. If I use the Ethernet cable going to/from my laptop and switch with the dock, Ethernet will disconnect in a Teams meeting. If I use the cable with the built-in Ethernet port on my laptop, everything's fine.. Other devices on my network are unaffected. That's more along the lines of the scenario (sans switch) that others are running into. It sounds like your situation has a broader scope, in that all devices connected to your router are disconnected.

Microsoft Teams Kills all Network Connectivity During Calls
