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.
