Check your real-time network connection information including connection type, effective connection type, downlink estimate, RTT, online status, public IP and available network details.
Check your available internet and network connection details.
If a particular value is not supported by your browser, the tool will display “Not available”.
Use this free Network Information Checker to view network and internet connection details available from your device and browser. The tool detects supported connection information without requiring any software installation.
Depending on your browser and device, the tool can display connection type, effective connection type, estimated downlink speed, round-trip time, data-saver status, online status and public IP information.
Network information describes how your device is currently connected to the internet and the connection characteristics available to the browser. This information can be useful when troubleshooting slow or unstable internet connections.
Connection type describes the type of network connection reported by the browser when supported. Depending on the device and browser, this can include Wi-Fi, cellular, Ethernet or another connection type.
Effective connection type, often shown as ECT, provides an estimate of the quality of the connection. Supported browsers may report values such as 4g, 3g, 2g or slow-2g.
Downlink is a browser-provided estimate of the available download bandwidth. It is not the same as a dedicated internet speed test and should be treated as an estimate.
RTT stands for Round Trip Time. It represents an estimate of how long it takes for data to travel to a network destination and for a response to return. Lower RTT generally means lower network latency.
Modern browsers restrict access to certain device and network information for privacy and security reasons. Browser support also differs between browsers and operating systems. When information is unavailable, this tool shows “Not available” rather than guessing a value.
Network information can help identify whether your browser is online, whether the browser reports a cellular or Wi-Fi connection, whether the estimated connection quality has changed and whether latency appears unusually high.
A Network Information Checker displays information exposed by the browser and public IP lookup services. A dedicated speed test actively transfers test data to measure download and upload performance. Therefore, the two tools serve different purposes.
Yes. This Network Information Checker is free to use online and does not require software installation.
A Network Information Checker displays network and connection details that are available to the browser and public IP lookup service.
Some browsers may provide connection type information, but browsers do not always expose whether a device is specifically using Wi-Fi or Ethernet.
ECT means Effective Connection Type. Supported browsers can report values such as 4g, 3g, 2g or slow-2g.
Downlink is a browser-provided estimate of available download bandwidth. It is not a replacement for a dedicated speed test.
RTT means Round Trip Time and represents an estimate of network round-trip latency.
Your browser or operating system may not expose that particular network property. The tool does not invent unavailable information.
Yes. The tool can use a public IP lookup service to determine the public IP address visible to the internet.
Browser-provided values such as downlink and ECT are estimates. Public IP information represents the address visible to the lookup service at the time of the check.
Yes. The Network Information Checker is free to use online.
