Video calls freeze or stutter
Zoom and Teams keep freezing on me even though my internet is fine. Why?

Short answer
Video calls need steady upload, not fast download. Wi-Fi interference, a background sync, or an old camera driver breaks that steadiness. The quickest thing to try first: test upload speed — Run a speed test and look at the upload number. Anything under about 3 Mbps upload will struggle with video, no matter how big the download figure is. Most people are done in about 10 minutes.

Move to 5 GHz or a cable
Connect to the 5 GHz network name, or plug in an Ethernet cable. This single change fixes most stuttering in home offices.
- 3
Pause background sync
Pause OneDrive, Dropbox, Steam and Windows Update during the call. They quietly saturate your upload.
- 4
Turn off virtual backgrounds and HD
In the app's video settings switch off HD, background blur and touch up. These use the processor hard on older laptops.
If none of that worked
If only one app freezes, reinstall it and update the camera driver. If every app freezes, the problem is the network and you should test with a phone hotspot to confirm.
