What to do if the LNK/ACT LED does not light up on my ZyXEL Communications Network Router?
- TTony FernandezJul 30, 2025
If the LNK/ACT LED on your ZyXEL Communications Network Router isn't lighting up or flashing when a device is connected, ensure the connected device is powered on and properly connected to the switch. Also, confirm that the Ethernet cards on the connected devices are functioning correctly and that the network cable is no longer than 100 meters.
