What Is My Connection Type? Network Info

What your browser reports about your network connection is shown above. Through the Network Information API, some browsers expose an effective connection type (like 4g or 3g), a rough downlink estimate in megabits per second, and whether you have data-saver turned on.

These values are deliberately coarse. The effective type buckets your real-world speed into slow-2g, 2g, 3g or 4g based on recent performance rather than the literal radio technology, so a fast home Wi-Fi connection typically reports 4g. It is a hint for adapting content, not a precise speed test.

Support is uneven. Chromium-based browsers expose the most detail, while Safari and Firefox expose little or nothing, so an empty value above simply means your browser chooses not to share it.

What you should know

Why sites collect it

Sites use connection hints to adapt: sending smaller images on slow links, deferring heavy scripts, honouring data-saver, and pre-loading more aggressively on fast connections. It helps pages feel fast on poor networks.

Privacy implications

Connection type is a low-to-moderate signal. On its own it barely narrows you down, but a data-saver flag or an unusual speed class adds a little entropy to a fingerprint. It does not reveal your provider or location.

How to change or hide it

There is no user setting to spoof this directly, though turning data-saver on or off changes what is reported. Browsers that do not implement the API (Safari, Firefox) simply reveal nothing here, which is the most private option.

Frequently asked questions

Is this a speed test?

No. It reports a coarse effective connection class and a rough estimate the browser already has, not a fresh measurement. A real speed test transfers data to time it.

Why is my connection type blank?

Your browser probably does not implement the Network Information API. Safari and Firefox largely do not, so they report nothing here.
