Test another device first. If every device is offline, restart the modem/router and check your internet provider.
Step by Step
- Try another website or app.
- Test another device on the same Wi-Fi.
- If all devices are affected, restart the modem/router using the manufacturer's normal restart procedure.
- Wait for the connection lights to stabilize.
- If only one device is affected, disconnect and reconnect its Wi-Fi.
- Restart the affected device.
- Check whether the internet provider reports an outage.
If That Doesn't Work
- Do not factory-reset the router as an early troubleshooting step; that can erase its configuration.
- A device can be connected to the router even when the router itself has no internet connection.
