Broadband Fault Diagnosis Wizard

Find the right troubleshooting guide and next test for your broadband problem.

Guided troubleshooting

Identify the next test, not just another possible fault

Choose the problem that best matches your experience, then narrow it down if you can. LinkSpeed will show the most relevant troubleshooting guide and tests. This wizard uses your answers, not hidden network measurements, and never claims to diagnose the ISP automatically.

What a guided result can and cannot establish

Compare Ethernet and Wi-Fi, repeat tests on more than one device, and check official ISP service status when the line is down. Broadband problems can involve the device, Wi-Fi, router, DNS, provider or test server. Do not buy hardware based solely on a questionnaire.

Every troubleshooting topic listed on the hub is available through the specific-problem selector above. For detailed advice, see the Broadband Troubleshooting Hub or Home Network Guides. Your answers stay in this page; the wizard does not submit or store them.
