Start with the simple checks. Change one thing at a time so you can tell which step helped.
A restart can clear temporary router faults, but it will not fix an outage, damaged cable or account issue. First, note what changed recently and whether the same issue affects another device. This helps separate a device-specific fault from a wider network or service issue.
Troubleshooting steps
Check the basics
Save any work and tell other people at home that the connection will pause. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Review the settings
Use the router power button or unplug its power supply; do not press the reset pinhole. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Test one change
Wait about 30 seconds, reconnect power and give the router several minutes to become ready. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Confirm the result
Check the internet light and test more than one device before changing settings. After each change, repeat the action that originally failed and give the device a moment to reconnect or refresh.
Helpful note
A restart is different from a factory reset, which can erase custom network names and provider settings.
When to get more help
If these checks do not resolve the issue, contact the relevant device maker, internet provider or app support team. Include the exact model, software version, any error message, what you have already tried and when the problem began. Avoid sharing passwords, verification codes or private account details in a public forum.
For equipment that is hot, damaged, wet or making unusual electrical sounds, stop using it and seek qualified support. Do not open power supplies, batteries or mains-powered equipment.
Settings and menu names vary by model and software version. Use the manufacturer's current instructions for device-specific steps, and back up important files before making changes that could remove data.
