What Is an Internet Speed Test?

An internet speed test measures your download speed, upload speed, ping (latency), and jitter to help you understand connection quality for streaming, gaming, and video calls.

Frequently Asked Questions

How often should I run a speed test?
Run a speed test at different times of day to spot patterns. ISP congestion often peaks in evenings. Testing on both Wi-Fi and Ethernet helps identify whether slowdowns are router-related or ISP-related.
Why does my speed test show different results each time?
Speed test results vary based on server load, network congestion, time of day, and your device state. Run multiple tests at different times for an accurate picture. Results on Wi-Fi also vary with interference and distance from your router.
What does ping and jitter mean?
Ping measures the latency or response time of your connection in milliseconds, while jitter shows the variability of latency. Lower values mean a more stable network.
How can I find my ISP provider?
The speed test detects your ISP provider automatically based on your IP address, allowing you to see which company provides your internet service.
Can I test my internet on different devices?
Yes, this Internet Speed Test works on desktops, laptops, tablets, and mobile devices, helping you measure performance on any connection.
What upload speed do I need for video calls and live streaming?
For HD video calls (Zoom, Teams), you need at least 1.5 Mbps upload. For 1080p live streaming on Twitch or YouTube, you need 4-6 Mbps upload. For 4K streaming, aim for 15+ Mbps upload. Check your upload speed separately from download speed.
What is a good download speed for streaming?
For Netflix or YouTube in 4K you need at least 25 Mbps. HD streaming requires about 5 Mbps. If multiple people stream simultaneously, multiply accordingly.
Why is my Wi-Fi slower than my ethernet?
Wi-Fi is affected by interference, distance from the router, and congestion. For the most accurate speed test results, connect via Ethernet cable directly to your router.
Does the number of connected devices affect my speed test?
Yes. Other devices streaming, downloading, or running updates consume bandwidth during your test. For the most accurate result, pause other devices and run the test with only your testing device active.

How Internet Speed Tests Work

An internet speed test measures the performance of your internet connection by testing download speed, upload speed, ping (latency), and jitter. It works by transferring data between your device and a test server and measuring how fast that data moves. Use this free speed test to check if your ISP is delivering the speeds you are paying for.

What internet speed do I need for streaming and gaming?

For most households, download speeds of 25 Mbps or higher are considered broadband. For streaming 4K video you need at least 25 Mbps, HD video needs around 5 Mbps, and video calls require about 1-3 Mbps. For online gaming, ping matters more than raw speed - under 50ms is good, under 20ms is excellent.

What affects internet speed test results?

Ping (latency) measures the time in milliseconds for data to travel from your device to a server and back. Lower ping means faster response times. Jitter measures the variability in ping over time. High jitter causes choppy voice calls and lag spikes in gaming even if average ping seems acceptable.

Why is my internet speed slower than expected?

Common causes include Wi-Fi interference (use Ethernet for accurate results), network congestion during peak hours, too many devices sharing bandwidth, old router firmware, or your ISP throttling your connection. Run the test at different times of day to compare. If speeds are consistently below what you pay for, contact your ISP.
