This chapter shows you how to use the Configuration Utility (or Utility) to secure, manage and
set up Quality of Service (QoS) on your powerline network.

5.1 Overview

The PLA-4xx is designed as a plug-and-play network expanding solution. This means that
once you complete your hardware connections, the PLA-4xxs in your network (without
additional configuration) are able to communicate with each other by sending and receiving
information over your home's electrical wiring (A).

Figure 21 Example Network Setup

All HomePlug AV compliant powerline adapters within range can join your network. The
range varies depending on the quality of your home's wiring.

network security.

5.1.1 Powerline Network Security

When the PLA-4xxs communicate with each other, they use encryption to protect the
information that is sent in the powerline network. Encryption is like a secret code. If you do
not know the secret code, you cannot understand the message. The HomePlug AV standard
uses 128-bit AES (Advanced Encryption Standard) to safely transmit data between powerline
adapters.
