What to do if…
your router resets unexpectedly and all your connected devices lose internet at once

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Assume either an ISP outage or a router reboot/reset. Do one clean reboot sequence and check your ISP’s official outage or status tool before changing Wi-Fi names, passwords, or router settings.

Do not do these things

  • Don’t press and hold the router’s “RESET” button unless you intend a factory reset; it can erase your Wi-Fi name, password, and custom settings.
  • Don’t keep unplugging and replugging equipment repeatedly in a panic; it can delay reconnection and make support diagnostics harder.
  • Don’t change multiple network settings at once to “try things”; you can accidentally lock yourself out.
  • Don’t give everyone a new Wi-Fi password until you know whether the router simply rebooted or actually factory-reset.
  • Don’t assume the problem is only Wi-Fi if every connected device lost internet at the same time.

What to do now

  1. Check for immediate household risks. If phone service, security monitoring, medical alert devices, work VPN, or smart locks depend on your home internet, assume they may be offline. Use a mobile phone or another available connection as your backup and tell others in the home.

  2. Look at the modem, ONT, gateway, and router lights. If you have two boxes, check both. If the lights look like they are still booting or connecting, give them a few minutes before intervening.

  3. Do one clean reboot sequence, not a factory reset.

    • If you have a combined gateway: unplug its power, wait about 30 seconds, plug it back in, and let it fully boot.
    • If you have a separate modem or ONT and router: unplug both, wait about 30 seconds, then power on the modem or ONT first. When it looks stable, power on the router and let it fully boot.
    • Use the power cable or power button. Do not press and hold a small recessed “RESET” button.

  4. Use your ISP’s official outage or status tool before changing settings. Many ISPs show outages and run tests in their app or website, often under “Outage,” “Service status,” or “Troubleshoot.” If there is a known outage, stop changing things and note when the outage started.

  5. Check whether your router actually factory-reset. Common signs include:

    • Your usual Wi-Fi name disappeared or changed.
    • Your Wi-Fi password stopped working.
    • The Wi-Fi name or password now matches the default details printed on the router, gateway, or ISP label.
    • Custom settings such as guest Wi-Fi, parental controls, port forwarding, or mesh settings disappeared.

  6. Test one wired connection if you can. If you have an Ethernet-capable device and cable, connect it to the router or gateway. If wired internet also fails, the problem is more likely on the ISP, modem, ONT, or gateway side than Wi-Fi alone.

  7. Contact your ISP support if service still is not back. Use a short summary: “My router or gateway reset or rebooted unexpectedly; all devices dropped at once at [time]; I did one clean reboot; the outage tool shows [result].” Ask whether your modem, ONT, or gateway appears online from their side and whether they can see recent errors or resets.

  8. Use a temporary fallback for essentials. Use a phone hotspot or another available connection for urgent work, calls, messages, or care needs. Avoid changing router settings or Wi-Fi passwords unless you confirm a factory reset or your ISP tells you to.

What can wait

  • You do not need to decide right now whether to buy new equipment or change providers.
  • You can postpone advanced steps such as factory reset, firmware updates, mesh reconfiguration, channel changes, or replacing cables until you have checked outage status and tried one clean reboot.
  • You do not need to reconnect every device immediately. Get one phone, laptop, or wired device online first, then reconnect the rest later.
  • You do not need to diagnose whether the fault is the router, modem, ONT, gateway, or ISP before contacting support.

Important reassurance

When every device drops at once, it is often an ISP outage, a temporary equipment reboot, or a provider-side update rather than something you caused. One calm reboot plus an outage check reduces the chance of making the problem worse.

Scope note

These are first steps to stabilize the moment, check whether this is an outage or a local equipment issue, and avoid irreversible settings changes. Repeated resets, failed equipment, or damaged cabling may need ISP diagnostics, manufacturer support, or hardware replacement later.

Important note

This is general information, not professional, technical, security, legal, financial, medical, therapeutic, or ISP-specific advice. If you rely on internet for safety or care devices, treat the outage as time-sensitive, use a mobile phone or another available connection for urgent calls, and contact your provider promptly.
