CHAPTER 5 Using the Powerline Configuration Utility 5.1 Overview 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. The PLA4231 is designed as a plug-and-play network expanding solution. This means that once you complete your hardware connections, the PLA4231s 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 11 Example Network Setup A All HomePlug AV compliant powerline adapters within range can join your network. The range varies depending on the quality of your home's wiring. Note: See Section 5.1.1 on page 27 for more information on enhancing your powerline network security. 5.1.1 Powerline Network Security When the PLA4231s 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. For the powerline adapters to communicate with each other they all need to use the same network name. This network name allows the powerline adapters to understand the encrypted information sent in the powerline network. PLA4231 User's Guide 27
