Network Quality Tester

About Network Quality Tester

Monitor your network connection quality in real-time using the Network Information API. While direct Wi-Fi signal strength (RSSI) is not available through web APIs, this tool provides comprehensive network quality metrics including connection type, effective speed, bandwidth, round-trip time, and more. Perfect for diagnosing network issues, testing connection stability, and monitoring performance.

How to use:

1. Click 'Start monitoring' to begin tracking network quality metrics.
2. View real-time connection type and effective connection speed.
3. Monitor downlink bandwidth and round-trip time (RTT).
4. Check if data saver mode is enabled on your device.
5. Run speed tests to measure download/upload speeds and latency.
6. View connection quality rating based on current metrics.
