Our speed test uses Cloudflare's global network. Results are accurate within 5% for most connections. Close background apps, use Ethernet if possible, and run the test 3 times for best accuracy.

25 Mbps handles HD streaming for one user. 100 Mbps supports a household with multiple devices. For gaming, ping under 50ms matters more than raw speed. 4K streaming requires 25 Mbps per stream.

ISPs advertise maximum speeds. WiFi alone reduces speeds 20-40%. Network congestion, router age, and device limitations all reduce real-world speeds. Test via Ethernet for the most accurate plan comparison.

Bufferbloat is when your router's queue fills during downloads, causing latency spikes. Even a 500 Mbps connection with severe bufferbloat will lag during gaming or video calls. Our test measures this — aim for grade A or better.

Yes, a typical test uses 40–100 MB. If you're on a metered data plan, consider connecting to WiFi first or check your remaining allowance.
