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

Short answer

Assume either an ISP outage or a router reboot/reset. Do one clean reboot sequence and check your ISP’s outage/status tool before changing Wi-Fi names, passwords, or 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/replugging repeatedly in a panic (it can delay reconnection and complicate support diagnostics).
  • Don’t change multiple network settings at once “to try things” (you can accidentally lock yourself out).
  • Don’t immediately distribute a new Wi-Fi password until you’re sure the router didn’t simply reboot.

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 internet, assume they may be offline. Use a mobile phone as your call backup and tell others in the home.
  2. Look at the modem/ONT and router lights (two boxes matter if you have them). If they look like they’re still booting/connecting, give them a few minutes to finish before intervening.
  3. Do one clean reboot sequence (not factory reset).
    • If you have separate modem/ONT and router: power off both, wait at least ~30–60 seconds, then power on the modem/ONT first. When it looks stable, power on the router and let it fully boot.
  4. Use your ISP’s official outage/status tool before you change settings. Many ISPs show outages and run tests in their app/website (often under “Outage,” “Service status,” or “Troubleshoot”). If there’s a known outage, stop troubleshooting and note when it started.
  5. Check whether your router actually factory-reset. Common signs:
    • Your usual Wi-Fi name disappeared/changed.
    • Your password stopped working.
    • The Wi-Fi name/password now match the sticker on the router/gateway (default details).
  6. Test one device directly if you can. If possible, connect a laptop/PC by Ethernet to the router. If wired also has no internet, it points to the ISP link/modem/ONT side rather than Wi-Fi only.
  7. If service still isn’t back, contact your ISP support with a tight summary.
    • “Router reset/rebooted unexpectedly; all devices dropped at once at (time); I did one reboot sequence; outage tool shows (result).”
      Ask them to check whether your modem/ONT shows as online from their side and whether they see errors/resets.
  8. If you need internet right now, use a temporary fallback. Use a phone hotspot for essentials. Avoid major account/password changes while the home connection is unstable.

What can wait

  • You don’t need to decide right now whether to buy new equipment or change providers.
  • You can postpone advanced steps (factory reset, firmware updates, mesh reconfiguration) until you’ve confirmed outage status and spoken to the ISP if needed.
  • You don’t need to reconnect every device immediately—get one device online first, then expand.

Important reassurance

When every device drops at once, it’s often a normal ISP outage or a routine equipment reboot/update rather than something you “caused.” A single calm reboot plus an outage check reduces the chance of making it worse.

Scope note

These are first steps to stabilize, confirm whether it’s an outage vs. a local equipment issue, and prevent irreversible mistakes. Repeated resets may require ISP diagnostics or a hardware replacement later.

Important note

This is general information, not professional or ISP-specific advice. If you rely on internet for safety or care devices, treat any outage as time-sensitive and contact your provider promptly.
