If your Netgear router is not operating, it could be for a variety of reasons. First, make sure the router is powered on and correctly connected to the modem. If the lights are off or flashing, it could be a connectivity problem. Try resetting your router by unplugging it for 30 seconds before plugging it back in. Ensure that the firmware is up to current, as outdated software might lead to performance issues. Interference from other devices, broken cables, or wrong settings could potentially be the cause. If the problem persists, please contact with our customer service for more troubleshooting methods to resolve your Netgear router not working.
