Network Info
WEBCheck browser-visible network status, effective connection type, downlink, round-trip time and data-saver state.
What is the Network Info tool?
Network info gives you a one-glance view of your network connection info exactly as your browser sees it: the effective connection type (like 4g), the estimated downlink in Mbps, the round-trip time (RTT) the browser is observing, and whether data-saver mode is switched on. The page reads these values straight from the browser's own connection monitor, so there is nothing to run and nothing to download — a network status check that answers the moment it loads.
It is the fastest first step when the internet feels off. Before running a full test, check what the browser itself believes: has the effective connection type dropped below 4g? Is RTT unusually high — a hint of congestion or a struggling Wi-Fi link? Is data saver quietly capping quality in the background? When you need deeper numbers, the natural next steps are Carbide's ping test, which measures live latency, jitter and loss to a host you choose, and the speed test, which measures real download and upload throughput. Together the three make a quick connection-quality triage kit that works on any phone or desktop.
Privacy here is as simple as it gets: everything on this page comes from the browser itself. No test traffic is generated, nothing is fetched to measure you, and nothing you see is sent anywhere — the values are read locally and stay on your screen. The tool is free, needs no sign-up, and works in English and Arabic.
How to use the Network Info
- Open the Network info page — the values load instantly from your browser.
- Read the effective connection type first: 4g means the browser rates your connection fast.
- Check the RTT value — the lower it is, the snappier your connection feels.
- Note the downlink estimate and whether data-saver mode is active.
- If anything looks off, run the ping test for live latency and the speed test for real throughput.
Frequently asked questions
What is RTT?
Round-trip time: how long a small piece of data takes to travel to a server and back, in milliseconds. Low RTT is what makes pages, calls and games feel responsive. The value here is the browser's running estimate from recent traffic — for an active measurement against a specific host, use the ping test.
What does "effective connection type 4g" mean?
It is the browser's classification of your connection quality based on recently observed speed and latency — not the radio you are on. Wi-Fi and fibre report 4g too, because 4g is simply the top bucket (the scale runs slow-2g, 2g, 3g, 4g). Seeing 3g on a fibre line means the browser is currently observing poor performance.
Why do these values differ from a speed test?
Because they are passive estimates, not measurements. The browser infers downlink and RTT from whatever traffic recently happened, and caps the downlink value it reports, while a speed test actively pushes data to measure real capacity. Use this page as the quick health glance and the speed test when you need accurate throughput numbers.
How do I check my internet connection quality?
Start here for the instant picture — connection type, RTT and data-saver state. Then run the ping test for stability (latency, jitter and loss over time) and the speed test for bandwidth. Slow pages with a decent downlink but high RTT point at a latency problem; a low downlink points at throughput.
Why do some fields show as unavailable?
The Network Information API behind this page is not implemented equally everywhere: Chrome, Edge and most Android browsers expose it fully, while Safari and Firefox expose little or none of it. A missing field means your browser does not share that value — nothing is wrong with your connection.
What is data-saver mode?
A browser or system setting that asks sites to send lighter versions of pages — smaller images, less prefetching. If it shows as on here and you did not expect that, it may explain blurry images or reduced video quality; you can switch it off in your browser settings.
Is this free, and is anything sent anywhere?
Free, no sign-up, no limits — and nothing is sent. The page reads values your browser already maintains and displays them locally; it generates no test traffic and stores nothing. That also makes it safe to check as often as you like, even on a metered connection.
