How Does a Packet Loss Test Work?
- 1We connect you to a test server.
The closest suitable server is chosen automatically.
- 2We measure ping and packet loss.
Small HTTP requests travel to the server and back; lost replies count as packet loss.
- 3We download test data.
Your browser receives real data using parallel connections.
- 4We upload test data.
Your browser sends data and we time the transfer.
- 5We analyze and display.
Everything is combined into a simple quality and stability estimate.
Frequently Asked Questions
What is packet loss?
Packet loss means data packets never reach their destination. It causes stuttering, dropped calls and lag spikes that speed tests often hide.
What is a good Internet speed?
10–25 Mbps for browsing, 25+ for HD, 100+ for 4K or busy households.
Why does my speed change between tests?
Wi-Fi signal quality, network congestion, background downloads and server load all affect results.
Can a browser measure packet loss?
Yes. By sending many small HTTP requests and counting missing replies, a browser can estimate packet loss without raw UDP access.
