Understanding Powerline Network Security
A Powerline network consists of two or more Powerline adapters using the same network 
encryption key. Securing your network is crucial. By encrypting the information you send over 
the Powerline AV Ethernet Adapter, you help to keep it secure from hackers. If you do not set 
up security on your network, anyone nearby with a Powerline network can potentially use 
their connection to gain access to your network and information you send over the Internet. 
This is especially relevant in settings such as apartment buildings, office buildings, dorm 
rooms, and other more populated areas. 
Powerline devices connected to the same network must use an identical encryption key. The 
security used by Powerline AV Ethernet Adapters is similar to the SSID and encryption keys 
used in wireless networks, but you do not need software to configure Powerline AV Ethernet 
Adapters. 
There are two ways to secure your Powerline network. 
• Use the Security button located on the adapter to automatically generate a random 
encryption key. See 
Set the Encryption Key .
• Use the XAV5001 Powerline Utility to configure your Powerline network with an 
encryption key that you specify. If you are already using Powerline or HomePlug devices 
then you will need to use the Powerline Utility. If not already installed, the Powerline Utility 
should be installed on your computer. See 
Installing the XAV5001 Powerline Utility on 
page  12.
For information about using the XAV5001 Powerline Utility to configure Powerline security 
or to prioritize Powerline network traffic using the Quality of Service (QoS) feature, see 
Chapter  2.
Note: To return the XAV5001 Powerline AV 500 Adapter to its factory 
default settings, see Reset a Device to Factory Settings on page  17.
Set the Encryption Key
You can use the Security button to change the default encryption key and set a private 
encryption key instead. The default encryption key is HomePlugAV.
Note: Before you change the Encryption key, you need to install the 
Powerline adapters and get them up and running. Otherwise, they 
might not be able to communicate with each other.
