Video calls freeze but speed tests look fine.
Calls need low loss, jitter and latency, not just throughput. Test near the router or wired and check other uploads, VPN and Wi‑Fi retries.
Packet loss; jitter; loaded latency; upload; VPN; RSSI.
Escalate persistent wired loss/jitter.
Show the technical detail
On a managed Wi-Fi plan
Correlate radio/WAN telemetry at call times; optimise or wire the workstation.
On another provider's router
Use provider diagnostics, then app/employer support.
What to be careful of
Do not diagnose call platform solely from Mbps.
