Frozen faces and robotic audio on calls are almost never a download problem — they are an upload or jitter problem. This page surfaces the metrics that actually decide call quality.

Why upload matters on calls

On a call you are sending video, not just receiving it. A 1080p group call needs roughly 4 Mbps down and 3.8 Mbps up, with steady jitter. Watch the upload and jitter tiles when you run the test.

Fixing choppy calls

Get closer to the router or go wired, drop your camera to 720p, and avoid sharing the line with a big upload (cloud backup, file sync) during meetings.
