Remove the powerline adapter from the outlet. Then connect an electrical device that you know
4
works into the same power outlet. This checks the status of the power outlet.
If the problem continues, contact the vendor.
5
The ETHERNET light does not turn on.
Check the hardware connections. See the Quick Start Guide.
1
Inspect your cables for damage. Contact the vendor to replace any damaged cables.
2
Check the Ethernet adapter on your computer and make sure it's enabled and working properly.
3
If the PLA4201 is connected to an Ethernet switch or router, make sure the device is working
4
correctly, and that the LAN network is working and configured correctly as well.
The HomePlug light does not turn on.
Check all PLA4201s on your network have the latest firmware installed. PLA4201s with the latest
1
firmware cannot communicate with PLA4201s using earlier versions of the firmware. Go to
4.4 on page 25
Use the PLA42xx Series Configuration Utility to detect all other HomePlug devices on your
2
powerline network. Make sure that the network name (sometimes called the network password) is
the same on all of your powerline adapters. See
the network name.
Check the DAK password and MAC address for all powerline adapters are typed correctly in the
3
utility. See Section 4.3 on page 24
Make sure that all your powerline adapters are HomePlug AV compliant. Check the package it came
4
in or ask your vendor. This PLA4201 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.)
Make sure that the powerline adapters on your network are all on the same electrical wiring.
5
Connect another powerline adapter into an outlet close to your PLA4201's power outlet. They are
probably now on the same electrical wiring. Check the HomePlug
powerline adapter was probably previously on separate electrical wiring. Ask an electrician for more
information on the electrical wiring in your building.
If your powerline network is using coaxial cable, check all powerline adapters are on the same
6
coaxial cable.
If your powerline network is using electrical wiring (not coaxial cable), check you do not have a
7
power meter between powerline adapters. Powerline signals cannot pass this.
