Basic steps you can try when your connection is not working properly.
Make sure your device is connected to the correct Wi-Fi network and has a usable signal.
If multiple devices have connection problems, restarting the modem or router may help.
Check download speed, upload speed, ping and other connection performance measurements.
If websites are not resolving correctly, use the DNS Checker to inspect public DNS records.
Use the IPv6 Checker to see whether your connection supports IPv6 connectivity.
If several devices remain offline after local troubleshooting, your Internet provider may need to investigate the connection.
Common questions about Internet connection diagnostics.
Network diagnostics is the process of checking different parts of a network connection to help identify connectivity or performance problems.
No. This page is designed for basic diagnostics. Use the NetSpeedCheck Speed Test for actual download, upload and latency measurements.
The browser's online status is only a basic indication. It does not guarantee that every website or service is reachable.
IPv6 availability depends on your ISP, router, device configuration and the network path to the destination.
First run a speed test, then compare results across different devices or connection types. You can also check ping, DNS and IPv6 connectivity using the NetSpeedCheck tools.
This page does not intentionally display your local or private IP address. Browser networking APIs provide only limited network information to web pages.
