Consistency matters
Jitter is the variation between latency measurements. A connection can have a reasonable average ping but still feel unreliable if individual packets arrive at inconsistent times.
What causes jitter?
Busy Wi-Fi channels, congestion, bufferbloat, overloaded routers and unstable links are common causes. Ethernet testing can help identify whether Wi-Fi is responsible.
How to reduce jitter
Move closer to the router, use Ethernet, reduce competing uploads, update network equipment and investigate quality-of-service or smart queue management features.
