Wi-Fi Troubleshooting
First work out whether the problem affects one device or every device on the network. That simple check helps separate a device setting from a router, modem or internet service issue.
Wi-Fi connected, but there is no internet
- Check the same network on another device.
- Look at the router or modem status lights and check for a service outage with your internet provider.
- Restart the affected device. If all devices are offline, restart networking equipment according to the manufacturer’s instructions.
- If only one computer is affected, forget and reconnect to the Wi-Fi network only after confirming you know the password.
Wi-Fi is slow or keeps dropping
- Test close to the router and compare with a wired connection if possible.
- Move the router to an open, central location away from large obstructions.
- Pause large downloads and check whether one device or app is using most of the connection.
- Update router firmware using the manufacturer’s official instructions.
One device cannot connect
Check airplane mode, Wi-Fi status, saved network details and any VPN or security software that may affect connectivity. On Windows, the built-in network troubleshooter can help identify common adapter and configuration issues.
When to contact your internet provider
If multiple devices remain offline after checking cables, status lights and a careful restart, contact your provider with the time the problem began and any modem or router error indicators. Avoid factory-resetting the router unless you have the configuration details needed to set it up again.
