A set of Homeplugs will consist of the following, at the very minimum: 

•    A Homeplug that is connected to the (modem) router. 
•    A Homeplug that is placed elsewhere in the home. 

Other Homeplugs can also be added to the network. In order to carry out the installation correctly, the items listed above will be required. 

An empty electrical socket will need to be available for each Homeplug you wish to install. Insert the Homeplug directly into an electrical socket, not into a trailing socket. Inserting a Homeplug into a trailing socket may cause signal loss. One of the UTP ports on the (modem) router must be free so that you can connect one of the two Homeplugs to it. Some Homeplugs are also supplied with a built-in electrical socket. The advantage of this is that you will not lose the ability to use the socket after inserting your Homeplug. 

It may be that the Homeplugs are unable to locate each other during installation. There are two possible causes of this.
 
1.    The Homeplugs may be too far apart. If your house has more than 4 groups, it may be the case that the Homeplugs cannot locate each other. To solve this problem, temporarily move them close together so that they can find each other more easily. If necessary, reinstall the Homeplugs. Once the Homeplugs have found each other, you can relocate the Homeplug that is not connected to the (modem) router to a location of your choice. Important: depending on the (electricity) groups in your home, certain distance limitations will apply. 

2.    Electricity networks cause interference and this may affect the connection between your Homeplugs. All devices connected to the electricity network will cause peaks in the signal and these may reduce the performance of the Homeplugs. If a device is continually powered on and the load on the electricity network mostly remains the same, the effects will be very small. If a device causes significant peaks, however, they may affect the Homeplugs. This is especially true of devices that switch on and off and devices such as washing machines that give rise to a significant peak load. Whether the Homeplugs will be affected by this will heavily depend on the group they are connected to. If they are connected to a different group, they may not be affected. For optimum performance, try inserting the Homeplugs into electrical sockets at various locations. The following types of device may cause peak loads:

• Plasma TVs 
• Halogen lamps 
• Light dimmers 
• Washing machines 
• Clothes dryers 
• Dishwashers 
• Microwave ovens 
• Ovens 
• Energy-saving lightbulbs 
• Vacuum cleaners 
• Hairdryers 
• Refrigerators/freezers 
• Air conditioning systems 
• Central heating boilers
