Chapter 11 Troubleshooting

2Check the DAK and MAC address for all power line adapters are typed correctly.

3Make 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.)

4Make 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 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.

5Check 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.

1Your power line adapters may be connected to electrical surge protectors. Connect them to standard power outlets.

2Your 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.

3Your 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.

4Your wiring may be old and/or low quality or with a long wiring path.
