Fix Common Home Internet Problems Before Replacing the Router

Find out what is failing

If only one device is offline, toggle its Wi-Fi, confirm airplane mode is off, and reconnect to the correct network. If several devices fail at once, check whether the modem or router shows an outage indicator and look for a service notice from your provider. Testing a wired connection, when available, helps distinguish a wireless coverage problem from an internet connection problem.

Restart with a plan

Save work before restarting equipment. Follow the modem or router maker's instructions, allow it time to reconnect, and avoid repeatedly unplugging devices in quick succession. Check that cables are seated and the power adapter belongs to that device. If a single website fails, try another trusted site or app; a local browser issue is different from a full network outage.

Improve coverage safely

Place the router in an open, central location rather than behind metal, inside a cabinet, or near obvious sources of interference. Update its firmware and use its official management app or documentation. If coverage remains poor, compare access-point or mesh options with the home's layout before buying equipment. Never weaken Wi-Fi encryption as a troubleshooting shortcut; restore secure settings after any diagnostic change.
