2. Firmware Update
A blinking green light can also indicate that your router is updating its firmware. Firmware updates usually occur automatically, and the blinking light is a sign that the process is underway. In this case, it’s essential to leave your router alone and let it complete the update.
3. WPS Mode
If your router is in WPS mode, it might blink green to indicate that it’s ready to connect to a new device. WPS is a feature that allows you to easily connect devices to your network without entering a password. If you’re not trying to connect a new device, you can disable WPS to stop the blinking light.
