Passphrase This feature allows you to generate a key or keys from a text (ASCII)
phrase, rather than enter keys in Hex.
To use this feature:
• Enter a word or group of printable characters in the Passphrase
field
• Click the "Generate Key" button.
• If encryption strength is set to 64 bit, then each of the four key
fields will be populated with key values. If encryption strength is

Like WEP, data is encrypted before transmission. WPA is more secure
than WEP, and should be used if all wireless stations support WPA.
PSK This is also called the "Passphrase" or "Network Key". Enter the
desired key value. Data is encrypted using a key derived from the
PSK. Other Wireless Stations must use the same key. The PSK must
be from 8 to 63 characters in length.
Key Lifetime This determines how often the encryption key is changed. You can
change the default value if desired.
Encryption The WPA-PSK standard allows different encryption methods to be
used. Select the desired option. Wireless Stations must use the same
encryption method.

Chapter 4
Wireless Client Configuration
This Chapter details the configuration required for each PC or other Wire-
less Client using the HomePlug 802.11g Access Point.
Overview
All Wireless Stations need to have settings which match the HomePlug 802.11g Access Point.
These settings depend on the mode in which the Access Point is being used.
Wireless Settings
For each of the following items, each Wireless Station must have the same settings as the
HomePlug 802.11g Access Point.
Mode On each PC, the mode must be set to Infrastructure.
SSID (ESSID) This must match the value used on the HomePlug 802.11g Access Point.
The default value is default
Note! The SSID is case sensitive.
WEP If WEP is enabled on the HomePlug 802.11g Access Point, each station
must use the same settings as the HomePlug 802.11g Access Point.
• The Encryption type or Key size (64Bit/128Bit) must match.
• Each Wireless Station must have the HomePlug 802.11g Access
Point’s Default Key in the same location in its Key table. (But it does
not have to be the Default key for the Wireless Station.)
• The HomePlug 802.11g Access Point must have the Default Key for
each Wireless Station in the same location in its Key table.
This is usually achieved by having all Stations and the HomePlug
802.11g Access Point use the same Key table, but having different
Default keys.
WPA-PSK If WPA-PSK is enabled on the HomePlug 802.11g Access Point, each
station must also be set to use WPA-PSK.
The PSK (also called Network Key or Passphrase) used on the HomePlug
802.11g Access Point must also be set on each Wireless station.

tion against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communica-
tions. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
· Reorient or relocate the receiving antenna.
· Increase the separation between the equipment and receiver.
· Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
· Consult the dealer or an experienced radio/TV technician for help.
To assure continued compliance, any changes or modifications not expressly approved by the
party responsible for compliance could void the user's authority to operate this equipment.
(Example - use only shielded interface cables when connecting to computer or peripheral de-
vices).
FCC Radiation Exposure Statement
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause
undesired operation.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The antennas used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.
Channel
The Wireless Channel sets the radio frequency used for communication.
¡EAccess Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA
and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent
Access Points use different Channels to reduce interference.
¡E In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest
signal is used. (This can only happen within an ESS.)
¡E If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the
same Channel. However, most Wireless stations will still scan all Channels to see if there
is an existing "Ad-hoc" group they can join.
CAUTION:
1) To comply with FCC RF exposure compliance requirements, a separation
distance of at least 20 cm must be maintained between the antenna of this
device and all persons.
2) This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.

Troubleshooting
Overview
This chapter covers some common problems that may be encountered while using the Home-
Plug 802.11g Access Point and some possible solutions to them. If you follow the suggested
steps and the HomePlug 802.11g Access Point still does not function properly, contact your
dealer for further advice.
General Problems
Problem 1: Can't connect to the HomePlug 802.11g Access Point to configure it.
Solution 1: If you don't know the Wireless settings of the HomePlug 802.11g Access
Point, you must use the HomePlug interface for configuration. Use a Home-
Plug adapter on your PC to connect to the HomePlug network.
Then use the Windows utility to locate the HomePlug 802.11g Access Point.
The Windows utility is able to locate the HomePlug 802.11g Access Point
even if its IP address is incompatible with your PC, or your PC and the
HomePlug 802.11g Access Point are using different HomePlug network
passwords.
Problem 2: My PC's wireless interface can't connect to the HomePlug 802.11g Access
Point.
Solution 2 Check the following:
• The SSID and wireless security settings on the PC match the settings on
the HomePlug 802.11g Access Point.
Note that if the SSID (network name) is not broadcast, you will not be
able to see the HomePlug 802.11g Access Point in your PC's list of
"Available Networks", so will not be able to select it. Instead, you must
configure the network details manually.
• On the PC, the wireless mode is set to "Infrastructure"
Problem 3: My PC's HomePlug interface can't connect to the HomePlug 802.11g Access
Point.
Solution 3 Check that your PC and the HomePlug 802.11g Access Point are using the
same HomePlug network password.

Windows TCP/IP
Overview
Normally, no changes need to be made to your Network. Adding the
HomePlug 802.11g Access Point does not change your network.
• By default, the HomePlug 802.11g Access Point will act as a DHCP client, automatically
obtaining a suitable IP Address (and related information) from your DHCP Server.
• If you don't have a DHCP Server on your LAN, you should use fixed (static) IP addresses
on each PC.
• If using Fixed (specified) IP addresses on your LAN (instead of a DHCP Server), there is no
need to change the TCP/IP of each PC. Just configure the HomePlug 802.11g Access Point
to match your existing LAN.
The following sections provide details about checking the TCP/IP settings for various types of
Windows, should that be necessary.
Checking TCP/IP Settings - Windows 9x/ME:
1. Select Control Panel - Network. You should see a screen like the following:
