Chapter 3: Configuration
Overview
The HomePlug device uses 56-bit DES encryption to block outside access. The key is set by
using the HomePlug Configuration Utility on the CD. By default, the protection is enabled.
However, it is recommended that you change the default network password. All your HomePlug
devices must use the same network password in order for the computers to be networked.
Make sure that all devices are loaded with the same network password.
Diagnose Powerline network
1. Diagnose a Local HomePlug Device
Double click the PowerPacket Utility icon on your desktop to open this utility screen shown
below
The Main tab shows the HomePlug units that are connected to the current computer and other
devices on the network. It will also display Mac Address of each device. The utility will refresh
the window, when there are changes in devices, and it will also allow you to connect to
different networks if multiple units are connected to your computer.
*Note* If the Link Quality is poor, and appears in red, or the Mac Address of any of the units
connected to this computer appears to be all 0’s, then you might have a defective unit. Please
contact technical support (Appendix G) **
*Note* If you do not see ANY unit in the device status and there is a device connected to your
computer, try to unplug all devices then plug them back in. Also make sure that the cable
connecting your computer to the HomePlug device is the right type and working correctly. If all

11
of this seems to be correct, and you still do not see the device in the Device window, try
rebooting your computer. If the problem still persists, please contact technical support
(Appendix G).
Part 2: Diagnose a Network HomePlug device
The Main tab shows all the other HomePlug Units on your powerline network. It will be
represented by MAC Address and will also show the available bandwidth to each unit (Units
farther away from the current computer might have a lower Data Rate since the distance is
farther). If you add or subtract units from your home network, you might want to re-Scan by
clicking the “Scan” button. This will rescan the network, and refresh with any changes.
**Note** Only units with the same Network Password will be shown. Please check that first to
make sure they all have the same network password (Case sensitive).
**Note** If the MAC Address of a unit shows all 0’s, this unit might not have a solid connection,
or might not connect at all. Please make sure the device was correctly installed and
connected.
•**Note** If there are Units in your home that you do not see in this Network scan, try to
unplug all devices, then plug them back in (Only do this with the Units that is not
displayed in the network screen, you don’t have to do this with all units. If the problem
persists, try to move the unit closer to this current unit (adjacent plugs on the same
wall socket is most preferable). If the problem still persists, the distance might be the
issue.

12
Setting Up Security on a Local HomePlug device
The Privacy tab will allow you to change the Network Password to the unit that is currently
connected to this computer. This network password encrypts all data that is sent from this unit
using 56-bit data encryption standard (DES), thus creating a secure home network.
**Note** Every unit on your home network MUST have the same Network Password for
connectivity to be established throughout your home. The default network password is
“HomePlug”.

13
Setting Up Security on a Network HomePlug device
The Privacy Tab will allow users to use one primary computer to control the Network
Password of all units on the home network.
First locate the DEK (Device Encryption Key) Key printed on the bottom of each device then
enter this Key into the Device Password area on the Main Tab. Click ‘Add’. This Device Key
will then appear in the bottom window. Add all the DEK Keys for each unit in your house. Now
you can go back to the Main Tab then change the password remotely from one computer using
PowerPacket Utility. This will allow you to change the password from one computer, instead of
changing the password individually.
**Note** DEK is unique for EACH HomePlug device. To use this feature, you will need to
input the DEK for each unit.

powerline network.
Appendix B: IP Addressing
What is an IP Address?
IP Stands for Internet Protocol. An IP Address is the identifier where other computers on the
network can contact your computer, when you are connected to the network using the TCP/IP
protocols. The format of IP addresses are 32bit numerical addresses in 4 groups of 3. It ranges
from 0-255 (For example: 255.255.255.255). This number allows your computer to be unique on
the same network and enables you to communicate with other computers on the network.
Dynamic IP Addressing
Dynamic IP Addressing is when the computer is automatically be assigned to an IP Address. This
IP Address is unique for each computer on the network.
Static IP Addressing
Static IP Addressing is when the computer is assigned a preconfigured IP Address. This Address
will never change and will always be the same. This scheme should be used if you want to keep
the same settings on each computer all the time. If the subnet of the network changes (subnet
is the first 3 groups of the IP), the subnet of the static computer must change also.

16
Appendix C: Glossary
Default Password
A password set by the manufacturer that is unique to each device and is used to generate a
Default Encryption Key (DEK). The DEK is used only for the purpose of encrypting management
commands that change the NEK so that the NEK is never sent in the clear over the powerline.
DHCP
Dynamic Host Configuration Protocol is a method in which IP addresses are assigned by server
dynamically to the clients on the network. DHCP is used for Dynamic IP Addressing and requires
a dedicated DHCP server on the network.
Encryption Key (EK)
64-bit pattern generated by a key derivation function. An EK is used in an encryption algorithm
to add security to transmissions between HomePlug devices in a logical network.
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be
wired to the network at all times to gain access.
Gateway
A gateway is a hardware and software device that connects two dissimilar systems, such as a
LAN and a mainframe. In Internet terminology, a gateway is another name for a router.
Generally a gateway is used as a funnel for all traffic to the Internet.
IEEE
The Institute of Electrical and Electronics Engineers. The IEEE describes itself as “the world’s
largest technical professional society—promoting the development and application of electro
technology and allied sciences for the benefit of humanity, the advancement of the profession,
and the wellbeing of our members.”
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network adapter card
connected by cable/air, that share applications, data, and peripherals. All connections are
made via cable or wireless media, but a LAN does not use telephone services. It typically spans
a single building or campus.
Logical Network
Two or more HomePlug devices that share a common Network Encryption Key (NEK) and that
communicate with encrypted transmissions.
Network
A network is a system of computers that is connected. Data, files, and messages can be
transmitted over this network. Networks may be local or wide area networks.
Network Password
A password set by the user that generates the NEK and defines the user’s logical network.

17
RJ-45
A connector similar to a telephone connector that holds up to eight wires used for connecting
Ethernet devices.
Router
Protocol-dependent device that connects subnet works together. Routers are useful in breaking
down a very large network into smaller sub networks; they introduce longer delays and
typically have much lower throughput rates than bridges.
Powerline Networking
Data transmission over powerlines.
Password
Sequence of characters that serves as input to a key derivation function that generates an
Encryption Key (EK).
Protocol
A protocol is a standardized set of rules that specify how a conversation is to take place,
including the format, timing, sequencing and/ or error checking.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks with Static IP
address, the network administrator manually assigns an IP address to each computer. Once a
Static IP address is assigned, a computer uses the same IP address every time it reboots and
logs on to the network, unless it is manually changed.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research Projects Agency (ARPA). It is
widely used in corporate Internet works, because of its superior design for WANs. TCP governs
how packet is sequenced for transmission the network. The term “TCP/IP” is often used
generically to refer to the entire suite of related protocols.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone services and / or fiber
optic cabling. WANs may span a city, a state, a country, or even the world.
