Frequently asked questions
Is the speed test free?
Yes, all basic speed and diagnostic tests are completely free and require no sign-up.
What do ping, jitter and packet loss mean?
Ping is connection latency, jitter is its variation, and packet loss is the percentage of data that didn't arrive. Low values mean a stable connection.
What speed do I need for 4K streaming?
At least 25 Mbps download is recommended for 4K streaming. Our test instantly shows whether your connection can handle it.
Why is my internet slow?
Common causes are Wi-Fi instead of a cable, an overloaded router, or an ISP-side issue. The AI advisor pinpoints the exact cause and fix.
