Question 1

How accurate is this WiFi speed test?

Accepted Answer

NetDiag measures your actual connection speed by transferring data to Cloudflare's global edge network. Results reflect real-world performance including download, upload, ping, and jitter.

Question 2

What is a good internet speed for gaming and streaming?

Accepted Answer

For 4K streaming you need at least 25 Mbps download. For competitive gaming, ping under 30ms and jitter under 10ms matter most. For video conferencing, aim for 10 Mbps upload.

Question 3

Why is my speed test result different from my ISP's advertised speed?

Accepted Answer

ISPs advertise 'up to' speeds under ideal conditions. Real-world speeds depend on network congestion, WiFi interference, device capabilities, and distance from your ISP's infrastructure.
