How to use Local LAN Wi-Fi Speed Test

3 simple steps to complete your task directly in your browser:

  1. Pair Devices on Same Network

    Open this page on two devices connected to the same Wi-Fi router (e.g. laptop and phone). Generate a 5-letter PIN or scan the QR code.

  2. Direct WebRTC Link Established

    Devices negotiate a direct, encrypted WebRTC DataChannel over your local wireless network without touching external servers.

  3. High-Frequency Latency & Jitter

    High-resolution timestamp ping packets sent every 50ms measure round-trip time (RTT) and signal jitter variations.

Common uses

  • Locate Wi-Fi dead zones and identify the best router antenna positioning in your house or office.
  • Verify if your Wi-Fi 6 or 5GHz network link actually reaches advertised speeds across rooms.
  • Troubleshoot game lag and streaming stutter by measuring real packet jitter and local latency.
  • Compare Ethernet cable throughput versus wireless Wi-Fi speeds between computers.
