Microsoft Teams crashes my entire Internet connection after starting a meeting
Hello Jared327 This is something you'll definitely want to report to our https://answers.microsoft.com/en-us/msteams/forum?sort=LastReplyDate&dir=Desc&tab=All&status=all&mod=&modAge=&advFil=&postedAfter=&postedBefore=&threadType=All&isFilterExpanded=false&page=1 tech support site.
What works for me was disabling "Network" optimization from Dell Optimizer tools.
I have a Dell Precision with WIndows 11.
I had a drop in connection everytime I would open Microsoft Teams, and it will persist even if I close the app or the web tab (from 400 Mbps to 0.5Mbps).
I tried everything from :
- updating drivers
- updating dock driver (USB connection to my laptop)
- disabling IPV6
- trying with and without AWS VPN
- tried the web app instead of desktop app for Teams
- Windows Update
- Dell Command Update
- Office 325 Update
- trying Wifi 2.4 and 5GHz
- trying direct Ethernet connection from router
Found out there were artificial intelligence from Dell on the network that was "Give maximum bandwith to the conference app I'm using". I disabled the option and my connection was normal again.
