Chapter 11 Troubleshooting
2 Check the DAK and MAC address for all power line adapters are typed correctly.
3 Make sure that all your power line adapters are HomePlug AV. Check the package it
came in or ask your vendor. This ZyXEL Device 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 ZyXEL Device's power
outlet. They are probably now on the same electrical wiring. Check the Link
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.
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.
