3 Make sure that all your power line adapters are HomePlug AV. Check the package it
came in or ask your vendor. This PLA450 can not detect earlier versions of HomePlug
power line 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 devices on your network are all on the same electrical wiring.
Connect another power line adapter into an outlet close to your PLA450’s power outlet.
They are probably now on the same electrical wiring. Check the Link LED. If it now
lights up your power line adapter was probably previously on separate electrical wiring.
Ask an electrician for more information on the electrical wiring in your building.
5 Check you do not have a power meter between power line adapters. Power line signals
cannot pass this.
V The signal on my power line network may be weak for the following
reasons.
1 Your power line adapters may be connected to electrical surge protectors. Connect them
to standard power outlets.
2 Your power line adapters may be located close to large appliances such as refrigerators
or air-conditioners that cause interference with the power line signal. Move the adapters
further away from such appliances to reduce interference.
3 Your power line adapters may be placed close to electrical devices such as electrical
insect-killers which produce radio waves. These may interfere with the power line
signals. Move the adapters further away from such electrical devices.
4 Your wiring may be old and/or low quality or with a long wiring path.
14.7 ENCRYPT Button Problems
This section applies only to PLA450s with the ENCRYPT button.
V The HomePlug light is already on, but I haven’t pressed the ENCRYPT button
yet.
Your device has already connected to another powerline device. Press the ENCRYPT button
for more than 10 seconds to release the connection.
V The HomePlug light does not turn on.
• Ensure you have pressed the ENCRYPT button on both devices.
• Wait for about a minute while the devices set up a connection.
• If that does not work, try again with both devices connected to a power strip next to each
other. If they now connect, then the devices were not on the same electrical circuit before.
