See your download speed in real-time. Other metrics appear as we test them.
Get your complete connection analysis with clear explanations.
How fast you can receive data. This affects streaming, downloading files, and web browsing.
How fast you can send data. This affects video calls, file sharing, and cloud backups.
Response time between your device and server. Lower is better, especially for gaming.
Consistency of your connection. Lower values mean more stable performance.
For most users, testing once a week or when experiencing issues is sufficient. If you're troubleshooting, run 2-3 tests at different times.
Many factors affect speed: time of day, network congestion, router location, number of devices connected, and your ISP's service plan.
Yes, the test downloads and uploads data to measure speed. A complete test typically uses 50-100MB of data, similar to streaming a short video.
Simple ways to improve your connection speed and reliability
Follow these practical tips to get the most from your internet connection.
Keep your router central, elevated, and away from walls, metal objects, and other electronics.
Switch to 5GHz Wi-Fi for less interference and faster speeds (if your devices support it).
Use Wi-Fi analyzer apps to find less crowded channels and change your router settings.
Restart your router monthly to clear memory and resolve minor issues.
Check for and install router firmware updates for security and performance improvements.
For critical tasks like gaming or video calls, use an Ethernet cable for maximum stability.
Disconnect unused devices from Wi-Fi. Each device shares your bandwidth.
Schedule large downloads for off-peak hours (late night or early morning).
Close apps that use internet in the background when you need maximum speed.
Enable QoS in your router settings to prioritize important traffic like video calls over downloads.
