Jitter Explained: Latency is the round-trip speed; jitter is the inconsistency between pings. High jitter (>30ms) causes packet retransmissions and corrupts large multi-gigabyte firmware downloads.

Frequently Asked Questions

What is ping jitter and why does it cause firmware download corruption?

Jitter is the variance in latency over time. Severe packet jitter can cause TCP window resizing, buffer overflows, and socket timeouts when downloading multi-gigabyte stock firmware packages.

What is an acceptable ping latency for downloading firmware?

A latency below 50ms is optimal, 50ms-100ms is standard broadband performance, and anything above 150ms may suffer from packet retransmissions and slower throughput.

How does this in-browser latency test work?

The tool fires controlled asynchronous HTTP requests with cache-busting timestamps to high-availability endpoints, measuring precise round-trip times (RTT) via high-resolution performance timers.
