How to fix ZyXEL Communications Network Router SYS LED if it does not turn on?
- JJennifer GarciaJul 30, 2025
If the SYS LED on your ZyXEL Communications Network Router doesn't turn on, ensure the power cord is properly connected to the power outlet and that you're using the correct power source (100 watts maximum, 100-240VAC/1A, 50/60Hz). Also, check that the power connector and wire are correctly connected to the device. Verify the network module is properly connected. Make sure the fuse is not burnt-out and replace it if necessary. If the issue persists, the LED or the unit itself may be faulty; in this case, contact your vendor.
