Initial Powerline Adapter Setup
NOTE: A minimum of two G.hn Powerline Adapters are required.
If you are setting up a G.hn Powerline network for the first time, then
follow the steps below.
If you are adding to an existing G.hn Powerline network, then skip to
Steps 3-5.
1. Plug one Powerline Adapter into a power outlet near your Network
Device (Modem, Router, or Access Point).
For maximum performance, please plug the Powerline Adapter
directly into the wall outlet. Do not plug into a power strip or surge
protector, as network performance could degrade significantly.
2. Connect the Powerline Adapter to your Network Device (Modem,
Router, or Access Point) with an Ethernet (RJ-45) cable. Wait 10
seconds for the Ethernet LED to light up GREEN, which indicates a
connection is established. A flashing GREEN light indicates that the
device is sending data.

Device Connection
3. Plug the additional Powerline Adapter into a power outlet
near the Internet-enabled device (ex. TV, PC, STB, DVR, etc.).
4. Connect this Powerline Adapter to the Internet-enabled device
(ex. TV, PC, STB, DVR, etc.). with an Ethernet (RJ-45) cable. The
Connection LED and Ethernet LED on both of the Powerline
Adapters should be GREEN, which represents a strong connection.
Pairing the Powerline Adapters
5. Press the Security Button on one Adapter until you see the
Security LED start blinking GREEN. Then press the Security
Button on the second Adapter until you see the Security LED
start blinking GREEN. The Security LED and the
Connection LED should be solid GREEN on both Adapters
when they are successfully paired.
Note: If you are adding to an existing G.hn Powerline network,
then press the Security Button on any Adapter in the existing G.hn
Powerline network until you see the Security LED start blinking
GREEN. Then press the Security Button on the Powerline Adapter
you are adding until you see the Security LED start blinking
GREEN.. The Security LED and the Connection LED will light up
GREEN on all adapters within the G.hn Powerline network.
6. Repeat Steps 3 to 5 to add additional Powerline Adapters.
Please note that up to 16 devices can be connected within
a G.hn Powerline Network.
You Have Succesfully Set Up Your G.hn Powerline Network!

Troubleshooting
The following information should help you diagnose basic setup
or installation problems.
Connection LED is OFF: The Connection LED shows that the
Powerline Adapter is connected to the G.hn Network. If the
indicator is off, then plug both Powerline Adapters that you are
attempting to pair into power outlets that are located within the
same room. The Connection LED should light up GREEN. If not,
then press the Reset Button on each adapter for more than 10
seconds. Afterwards, you can plug the units back into their
original location.
Ethernet LED is OFF: If the Ethernet LED fails to light up, check that
the LAN port of the Powerline Adapter is connected firmly to the
LAN port of the other device. To check the condition of the
Ethernet cable, use another cable to test the same connection.
Security LED is OFF: If the Security LED is off, then it means the
Powerline Adapter is not securely paired. Press the Security Button
on the Powerline Adapter for 2 seconds until you see the Security
LED start flashing GREEN.Repeat this on the other Powerline
Adapter. The Security LED and the Connection LED will light up
GREEN on both adapters. This means the adapters are now
securely paired and have a strong connection.
To join an existing G.hn Powerline network, press the Security
Button on any Powerline Adapter in the existing G.hn Powerline
network for 2 seconds until you see the Security LED start flashing
GREEN. Then press the Security Button on the additional Powerline
Adapter. The Security LED and the Connection LED will light up
GREEN on both adapters.
*If you have tried the above and are still experiencing problems, you
can reset all devices to factory default by pushing the Reset Button for
more than 10 seconds (until all the LEDs of the device blink).

1.5 How to understand the COVERAGE LED colors
The COVERAGE LED displays quality of the network and provides important
information that will provide solutions to common questions, such as why a High
Definition (HD) movie is not showing or shows with pixels. The COVERAGE LED
indicator will vary its color depending on the estimated speed of the Powerline
connection. The speed is measured in Megabits Per Second (Mbps).
Color
Information
RED
The current connection has low quality, basic Internet activities
ex. 5Mbps are possible but the Powerline is unable to transmit either
a Standard Movie or High Definition (HD) Movie.
ORANGE
The current connection has good quality and Internet activities ex.
greater than 5Mbps and less than 40Mbps to transmit Standard
Movie and HD Movie.
GREEN
The current connection has excellent quality and Internet
activities ex. greater than 40Mbps to transmit multiple Standard
Movies and HD Movies.

Chapter 2 G.hn/Powerline Setup
2.1 IP Configuration
DHCP MODE
GPL-2000S4 supports two kinds of management IP simultaneously.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE: The following procedure assumes you are running Windows. However,
the general steps involved are similar for most operating systems (OS).
Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2:Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead.

12
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.0.x.
NOTE: The following procedure assumes you are running Windows. However,
the general steps involved are similar for most operating systems (OS).
Check your OS support documentation for further details.
STEP 1:From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2:Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the 192.168.0.x (5<x<255) subnet with subnet
mask of 255.255.255.0. The screen should now display as shown below.
STEP 4: Click OK to submit these settings.

13
2.2 Logging In
Perform the following steps to login to the web user interface.
STEP 1: Start the Internet browser and enter the default IP address for the device
in the Web address field. For example, if the default IP address is
192.168.0.5, type http://192.168.0.5
STEP 2: A dialog box will appear, such as the one below. Input the default
Authentication Password.
