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

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
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
Update the firmware
A firmware bug can cause reboot loops. Log in (during a stable window) and update to the latest firmware.
-
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
Check the system log
In the admin panel, look at System Log for error messages that appear just before each reboot.
-
6
Factory reset
Back up your settings, then factory-reset the router. Reconfigure from scratch to rule out a corrupt configuration.
-
7
Consider replacing the router
If the problem persists after firmware update and factory reset, the hardware may be failing.
