How accurate is Speed2Up?

Speed2Up uses 46 globally distributed servers and RFC 3550 compliant jitter measurement for highly accurate results. Our multi-connection testing methodology provides results within 5% of your actual speed capability.

What is ping and why does it matter?

Ping measures latency - the time it takes for data to travel to a server and back. Lower ping (under 20ms) is excellent for gaming. 20-50ms is good for most activities. Over 100ms may cause noticeable lag in games and video calls.

What is jitter and why should I care?

Jitter measures the variation in ping times. High jitter (over 30ms) causes unstable connections, lag spikes in games, and choppy video calls. Speed2Up uses RFC 3550 standard measurement for accurate jitter reporting.

Why is my speed test result different from my ISP plan?

Several factors affect speed: WiFi vs wired connection, network congestion, router quality, distance from server, and ISP throttling. Speed2Up selects the nearest server automatically and provides AI analysis of your specific situation.

Does Speed2Up work on mobile devices?

Yes! Speed2Up is a Progressive Web App (PWA) that works on all devices including smartphones, tablets, laptops, and desktops. You can even install it on your home screen for quick access.

How do I improve my internet speed?

Common fixes: Use ethernet instead of WiFi, restart your router, update firmware, reduce connected devices, check for malware, or upgrade your plan. Our AI Doctor provides personalized recommendations based on your test results.

Is Speed2Up free to use?

Yes, Speed2Up is completely free with no registration required. We provide unlimited speed tests with full AI diagnostics at no cost.
