1

Make sure the PL-100 is properly connected to a power outlet. Make sure the outlet 

is working by plugging another electric device into it. If it is working, plug in the PL-

100 again. If the PL-100 LED still does not light, contact our technical support.

1

Use the PL-100 Configuration Utility to detect all other Homeplug devices on your 

power line network.  

2

Try plugging a second Homeplug device into an adjacent socket (to your PL-100) 

and see if the lights light up. If you are still having a problem, please contact our 

technical support line.

1

Check that all Ethernet cables are securely connected at all ports and are the 

correct type (Cat-5 or higher).

2

Check the Ethernet adapter on your computer and make sure it’s enabled and 

working properly. If the PL-100 is connected to an Ethernent switch or router, make 

sure the device is working correctly, and that the LAN network is working and 

configured correctly as well.
