“My router keeps resetting itself” can mean two different things, and the fix depends on which one you are seeing. This guide helps you tell them apart and covers the usual suspects.
Two different problems
- Random reboots. The router restarts or turns off every so often. Wi-Fi drops for a minute or two, then comes back with your settings intact.
- Settings revert to default. The router comes back with its default name and password, or you lose things like a guest network. This looks like a factory reset.
Many people describe both as “resetting,” but they can have different causes.
Common causes of random reboots
- Power problems. A faulty power adapter, a loose connector or an overloaded power strip can cause restarts. Using a different adapter with the correct specification may help, but check the voltage and current on your router’s label before trying one.
- Overheating. Routers placed in cabinets, on top of electronics or in direct sun can run hot (see can a hot router slow your internet). Give the router room for airflow.
- Firmware issues. Bugs in firmware can cause instability, and a failed update may leave the router unstable.
- Heavy load or a misbehaving device. Lots of devices or a problem device on the network may stress the router (see router crashing with too many connections).
- Aging or failing hardware. If the router is several years old and the problem has become more frequent, the hardware may be wearing out.
Steps to try, in order
- Check the power. Reseat the cable at both ends, use a wall outlet directly, and look for damage on the adapter and cord.
- Improve ventilation. Move the router to an open spot and keep it clear of other heat sources.
- Restart once properly. Unplug it for about 30 seconds and plug it back in.
- Check for firmware updates (see how to tell if your router needs an update) through the router admin page (routerlogin.net on many Netgear models). Do not unplug the router during an update.
- Disconnect devices and extras. Unplug everything but one computer, and see if reboots continue. Add devices back gradually.
- Consider a factory reset if the router behaves strangely after changes or an update. See how to factory reset a Netgear Nighthawk for the steps, and remember it erases your settings.
Note when the reboots happen. If they occur at regular intervals, or only when certain devices are active, that is useful information for Netgear support.
When settings revert to default
If the router really goes back to factory defaults, think about:
- A reset button being pressed accidentally, or held down by something pushing against it
- A failed firmware update
- Power interruptions during a configuration save
- A hardware fault
Check that nothing is pressing the reset button, update the firmware if possible, and consider contacting Netgear support if it keeps happening.
Is it time to replace it?
There is no single lifespan for every router, but many last several years. If the router is old and still reboots after the steps above, including a different power adapter and a firmware update, replacement may be more practical than further troubleshooting. If it is under warranty, ask the manufacturer first.
Is a factory reset a good idea?
It can help if settings or firmware are corrupted, but it will not fix a failing power adapter or overheating. Try the simpler checks first.
What about satellites?
If you use a Nighthawk mesh system or a satellite, restart the main router first and then the satellite. For mesh-specific problems, see common Orbi router problems.
FAQ
Why does my router keep restarting itself? Common causes are power supply problems, overheating, firmware bugs and failing hardware.
Can a bad power adapter cause a reboot loop? It can. Try a known-good adapter with the correct ratings.
Do I have to factory reset to stop the restarts? Not always. Fix power and heat problems first.
