NetDiag helps you check the network you are on right now. Review connection type, local IP, signal strength, link speed, frequency or channel, gateway, and DNS servers when the system provides them. Run a host check to measure TCP latency, look up DNS, and test gateway reachability so you can tell whether a slow or broken connection is on your device, your router, or farther out.
Check Wi-Fi details, TCP latency, DNS, and gateway reachability.
