2

Make sure the power button at the side of the PLA4231 is pushed in.

3

Remove the powerline adapter from the outlet. Then connect an electrical device that you know

works into the same power outlet. This checks the status of the power outlet.

4

If the problem continues, contact the vendor.

The Ethernet light does not turn on.

1

Check the hardware connections. See the Quick Start Guide.

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 PLA4231 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 HomePlug light does not turn on.

1

Check all PLA4231s on your network have the latest firmware installed. PLA4231s with the latest

firmware cannot communicate with PLA4231s using earlier versions of the firmware. Go to

Section

5.4 on page 30

or

Section 13.6 on page 90

for instructions on installing the latest firmware.

2

Use the

PLA42xx Series Configuration Utility

to detect all other HomePlug devices on your

powerline network. Make sure that the network name (sometimes called the network password) is

the same on all of your powerline adapters. See


or


for instructions on checking the network name.

3

Check the DAK password and MAC address for all powerline adapters are typed correctly in the

utility. See


or


for instructions on checking the DAK

and MAC address.

4

Make sure that all your powerline adapters are HomePlug AV compliant. Check the package it came

in or ask your vendor. This PLA4231 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.)

5

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 PLA4231’s power outlet. They are

probably now on the same electrical wiring. Check the HomePlug

light. 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.

6

If your powerline network is using coaxial cable, check all powerline adapters are on the same

coaxial cable.
