Teams client kills network performance
- Teams alone shouldn't be causing this type of substantial network drop for you, so this is definitely concerning. Do you have a ticket open with Support on this yet by chance? We might need to dive deeper into a netcap to understand what's really going on via the network and see what's taking away the chunk of your network here (Teams or other) in this case.
Rebooted laptop and restarted modem to start with a clean environment and network connection. Only app running is Edge with a single tab for the Ookla speed test:

I can do more of these tests throughout the day. Just let me know what else you need.
Thank you!

Microsofthi. same thing is happening to me. and I am using a macbook pro. Ever since I installed and log on to Teams, my network speed just crashed to 3mbps. I usually have 300mbps speed, especially on 5g wifi at home.
I really need to get this fixed because I use Teams almost every day and other people at home using the same wifi connection are getting affected by the sudden slow internet connection
- I have the same issue, Do we have any solution?
Martin_Grasso I went through a number of testing iterations with a Microsoft engineer and ultimately, nothing could be found. I was able to reproduce it on two different Microsoft devices (SB2 and SL2), but could not make it happen on my wife's Dell laptop, or my mobile device with the Teams client active. If you pursue it further and you do end up finding something, please post your results here as I would still like to know what's causing the problem.
Thank you!
- How frustrating that a Microsoft engineer isn't able to solve this issue. I have also experienced the exact same issue, performing a speed test and very similar results. This has to be a known and tracked issue somewhere, but found very little on it, just this other post here: https://answers.microsoft.com/en-us/msoffice/forum/all/ms-teams-shows-poor-connection-when-the-internet/1613e8a4-80da-48dd-9a26-069dc930cf39
Surely there must be more people having this same issue. I'm on a Virgin media connection in the UK, might this be implicated?
- I have opened Case # 34167598 as suggested, with the O365 Support team.
Sam Cosby I don't have a ticket open, but can get one created. Note that I have two surface devices; a Surface Laptop 2 (used for these tests) and a Surface Book 2 that has the same issue. There's another post referred to earlier in this thread the seems similar and the poster also has a Surface device. Maybe a coincidence but it's curious.
