Troubleshooting

Fix Router Keeps Rebooting

Stop your router from spontaneously restarting by diagnosing the most common causes — overheating, firmware bugs and power issues.

Updated 2026

  1. 1

    Check for overheating

    Place the router in the open with good airflow, away from other electronics. If it's hot to the touch, that's likely the cause.

  2. 2

    Check the power supply

    A failing power adapter causes random reboots. Try the original adapter and ensure the outlet is stable. Avoid power strips with other high-draw devices.

  3. 3

    Update the firmware

    A firmware bug can cause reboot loops. Log in (during a stable window) and update to the latest firmware.

  4. 4

    Disable problematic features

    Features like USB storage sharing or certain VPN settings can destabilise some routers. Disable them one at a time to isolate the cause.

  5. 5

    Check the system log

    In the admin panel, look at System Log for error messages that appear just before each reboot.

  6. 6

    Factory reset

    Back up your settings, then factory-reset the router. Reconfigure from scratch to rule out a corrupt configuration.

  7. 7

    Consider replacing the router

    If the problem persists after firmware update and factory reset, the hardware may be failing.

Frequently Asked Questions

Could a power outage have damaged the router?
Yes — power surges can damage router hardware or corrupt firmware. Try a firmware recovery procedure or contact the manufacturer.
Is there a way to schedule reboots instead?
Yes — some routers offer a scheduled reboot feature in the administration panel. A daily or weekly reboot can prevent build-up of memory issues.
