PLA4201 User’s Guide

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 PLA4201 is designed as a plug-and-play network expanding solution. This means that once you 
complete your hardware connections, the PLA4201s 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).

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.

Note: See 

 for more information on enhancing your powerline 

network security.

When the PLA4201s 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.
