What Is Fiber
Very likely

Your upload is choked. Fiber actually helps here.

Most cable plans ship asymmetric — a '1 gigabit' plan often has 35–50 Mbps upload. That's fine for browsing. It's not fine for Zoom + Dropbox sync + a security camera + a Twitch stream. Video calls drop because outbound packets are queued. DSL and 5G home have the same problem, worse.

Pause cloud sync and run a call

Disable iCloud, Dropbox, OneDrive, and Google Drive sync during meetings. Turn off phone photo upload. If your calls stabilize, you've confirmed the diagnosis.

If that doesn't fix it
Check your ISP for a higher upload tier

Some cable providers now offer mid-split DOCSIS 3.1 with 100–300 Mbps upload, but you'll need a compatible modem.

Fiber would help here · primary

Symmetric upload is fiber's killer feature. A 500/500 fiber plan will feel faster than a 1000/35 cable plan for anyone on calls, uploading content, or running a home server.
