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
Part 1: Diagnose a Local HomePlug Device
Double click the PowerPacket Utility icon on your desktop to open this utility
show in the screen below:
The Main tab shows the HomePlug units that are connected to the current
computer and oter devices on the network. It will also tell Mac Address of
each device. It will let you refresh the window, if you change devices, and
also will allow you to connect to different networks if multiple units are
connected to your computer.
13
*Note* If the Link Quality is poor, and appears 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, and 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 of this
seems to be correct, and you still receive nothing 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 represent them 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 reScan, 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).
14
**Note** If a Unit shows MAC Address of all 0’s, this unit might not have a
solid connection, or might not connect at all. If this is the case please
contact technical support (Appendix G).
**Note** If there are Units in your home, that you do not see in this
Network scan, try to unplug all devices, and plug them back in (Only do
this with the Units that you do not view 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 and that unit is still not shown on
the network, then the unit might be defective please contact technical
support (Appendix G). Otherwise if you view the unit working, distance
might be the only issue.
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). The DES Encryption is very secure, and very difficult to
crack, therefore your home network is very secure, and very difficult to
breach your 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”.
15
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.
You will have to go back to the Main Tab first then find the DEK (Device
Encryption Key) Key located on the bottom of each device. Enter this Key
into the Device Password area. Click Add. This Device Key will then
appear in the bottom window . Add all the DEK Keys for each unit in your
house. You can now go back to the Main Tab then change the password
remotely from one computer. This will allow you to change the password
from one computer, instead of changing the password individually.
**Note** The DEK is unique for EACH HomePlug device. To use this
you will need to input the DEK for each unit.

Appendix B: IP Addressing
What is an IP Addresses?
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 is ranged from 0-255. For example:
255.255.255.255. This number allows your computer to be unique on the same
network, and able to communicate with other computers on the network.
Dynamic IP Addressing
Dynamic IP Addressing is where the computer will automatically be assigned a
new IP Address. This IP Address will be unique to the network that it is working
on, and should not be the same as any other computer on the same network.
Static IP Addressing
Static IP Addressing is where the computer will have 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 also change.

Appendix D: 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.
59
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.
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.
60
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.
