What Is My Internet Connection?

Your connection type, effective speed category, downlink estimate and latency — detected from your browser's Network Information API. All local, nothing sent to our servers.

⚠️ Connection data comes from your browser's Network Information API and may not be available in all browsers (e.g. Firefox, Safari). Values are estimates, not precise speed test results. Use our Speed Test for accurate measurements.

What is the Network Information API?

The Network Information API is a web browser API that provides information about the device's network connection. It exposes properties such as the connection type (WiFi, cellular, ethernet), the effective connection type (slow-2g, 2g, 3g, 4g), an estimate of the available downlink bandwidth in megabits per second, and the round-trip time (RTT) latency estimate in milliseconds.

The API is currently supported by Chrome and Chrome-based browsers (Edge, Opera, Brave) and Android WebView. It is not supported by Firefox or Safari, which means connection type information may show as "Not available" in those browsers.

Effective connection types

  • 4g — good connection, suitable for HD video and most web content
  • 3g — moderate connection, suitable for standard definition video
  • 2g — slow connection, suitable for basic web browsing
  • slow-2g — very slow connection, text-only browsing

WiFi vs Cellular vs Ethernet

The connection type reported by the Network Information API describes the physical medium of your connection:

  • WiFi — wireless local area network connection
  • Cellular — mobile data connection (3G, 4G, 5G)
  • Ethernet — wired network connection
  • Bluetooth — Bluetooth tethering or network connection
  • None — no network connection detected
  • Other / Unknown — connection type cannot be determined

Note that even if you are connected via WiFi, the underlying internet connection may be fibre, cable, DSL, or another technology — WiFi only describes the wireless link between your device and your router.

Frequently Asked Questions about Internet Connection

Why does my connection type show as "Not available"?
The Network Information API is only supported by Chrome-based browsers. Firefox, Safari, and some other browsers do not expose this information, so connection type will show as "Not available" in those browsers.
Is the downlink speed accurate?
The downlink value from the Network Information API is an estimate based on recently observed network conditions, not a precise measurement. For accurate speed testing, use a dedicated speed test tool.
What is RTT?
RTT (Round-Trip Time) is the time it takes for a data packet to travel from your device to a server and back. Lower RTT means lower latency, which is important for real-time applications like video calls and online gaming.
