Why can none of my devices connect to my home Wi-Fi?

Start with one observation

Look for the normal Wi-Fi network name on two different devices. If neither can see it, check that the router has power and has finished starting. If they can see it but both are rejected, review the password and router status. If they connect but cannot browse, the issue is likely the internet path rather than joining Wi-Fi.

Check in priority order

1. Check power and the status lights or app for the router or mesh main unit. 2. Wait a few minutes after a restart; do not repeatedly power-cycle it. 3. Try one device near the router. 4. Confirm that the Wi-Fi name you expect is actually visible. 5. If prompted for a password, use the current password rather than a saved old one. 6. Check whether the router app reports an internet or service problem.

Choose the next direction

A missing network points toward the router’s Wi-Fi service or startup. A password error points toward credentials or device settings. A connected Wi-Fi icon with no browsing points toward the internet connection. If only one device fails while others work, keep the investigation on that device.

Avoid a premature reset

Restarting the router is often a reasonable first check. A factory reset is not: it removes network settings and can require every device to be joined again. Use it only when the manufacturer tells you to.

Get help when

Contact the ISP if the router’s incoming service is down. Contact the device or router manufacturer if power is normal but the Wi-Fi network never returns, or all devices are refused after a confirmed password check.

Before making disruptive changes

• A factory reset removes Wi-Fi settings and should not be the first step.
