How does this speed test work?

This tool measures three key metrics: Ping latency (sends small requests to measure server response time), Download speed (downloads test files from CDN and times the transfer), and Upload speed (uploads random data to a test server). All testing happens in your browser.

Are the results accurate?

Results are affected by Wi-Fi signal strength, number of devices sharing bandwidth, server distance, and ISP throttling. For best accuracy, use a wired connection and run multiple tests.

Why is my speed slower than my plan?

Common reasons: 1) Wi-Fi signal loss through walls; 2) Multiple devices sharing bandwidth; 3) Old router; 4) ISP peak-time throttling; 5) Poor quality cables. Try connecting directly to the modem with an Ethernet cable.

Is my data private during the test?

Yes, completely. All testing happens in your browser locally. Test files use public CDN resources. Your IP address and test results are never logged or uploaded to any server.

What These Metrics Mean

Ping Latency: Round-trip time from your device to a server and back. Lower is better. Gaming and video calls need <50ms. <20ms Excellent, 20-50ms Good, 50-100ms Average, >100ms Poor.

Download Speed: How fast you receive data from the internet. Affects web browsing, video streaming, and file downloads. 100Mbps+ recommended for 4K streaming and large downloads.

Upload Speed: How fast you send data to the internet. Affects video conferencing, cloud backups, and live streaming. 20Mbps+ recommended for HD video calls.

Tips to Improve Speed

Use a wired Ethernet connection instead of Wi-Fi
Place your router in a central location, away from walls and metal objects
Regularly restart your router and modem
Check for background apps using bandwidth (auto-updates, cloud sync)
Use 5GHz band (faster but shorter range) instead of 2.4GHz
Upgrade to a Wi-Fi 6 or Wi-Fi 7 router
