2 Inspect your cables for damage. Contact the vendor to replace any damaged cables.
3 Check the Ethernet adapter on your computer and make sure it’s enabled and working
properly.
4 If the PLA-4xx is connected to an Ethernet switch or router, make sure the device is
working correctly, and that the LAN network is working and configured correctly as
well.

The LINK LED does not turn on.
1 Use the PLA-4xx Series Configuration Utility to detect all other HomePlug devices on
your powerline network. Make sure that the network password is the same on all of your
powerline adapters.
2 Check the DAK and MAC address for all powerline adapters are typed correctly.
3 Make sure that all your powerline adapters are HomePlug AV compliant. Check the
package it came in or ask your vendor. This PLA-4xx can not detect earlier versions of
HomePlug powerline adapters such as HomePlug 1.0 or 1.0.1. (Although they can
coexist on the same electrical wiring without interfering with each other.)
4 Make sure that the powerline adapters on your network are all on the same electrical
wiring. Connect another powerline adapter into an outlet close to your PLA-4xx’s power
outlet. They are probably now on the same electrical wiring. Check the Link
LED. If
it now lights up your powerline adapter was probably previously on separate electrical
wiring. Ask an electrician for more information on the electrical wiring in your building.
5 If your powerline network is using coaxial cable, check all powerline adapters are on the
same coaxial cable.
6 If your powerline network is using electrical wiring (not coaxial cable), check you do not
have a power meter between powerline adapters. Powerline signals cannot pass this.
