Chapter 1 Introduction
NexusLink’s GPL-1200WAC is designed to meet the growing demand for perfect
connectivity and coverage across multiple devices connected concurrently throughout the
home. The G.hn Powerline Wi-Fi extender allows users to take Wi-Fi with them anywhere
throughout the home or backyard and enjoy a seamless wireless experience.
1.1 System Requirements
Computer or network devices with wired or wireless network interface card
Any connected devices must feature a network port
Web browser (Microsoft Internet Explorer 4.0 or above, Google Chrome web
browser, Opera web browser, or Safari web browser)
An available AC power socket (100 – 240 V, 50/60Hz)

Chapter 2 How to Install GPL-1200WAC
(A) Understanding the AC1200 G.hn Powerline Adapter
How to Create a Basic (2 unit) G.hn Powerline Network – Recommended Setup
A G.hn Powerline Network can consist of a minimum of 2 and up to 16 devices total.
**The GPL-1200 can be replaced by another G.hn Powerline Adapter.
NOTE: The following steps show how to create or add onto a G.hn Powerline Network
using a GPL-1200WAC.
(A minimum of two G.hn Powerline Adapters are required to create a proper connection.)
If this is the first time you are setting up a G.hn Powerline Network please continue to
Section B.
If you already have an established G.hn Powerline Network and are adding an
additional adapter, please skip to Section C.

(B) Creating a New G.hn Network
1. Plug a GPL-1200* unit into the power outlet closest to the Network Device
(Modem, Router). Do not plug the adapter into a power strip or surge protector,
as network performance could degrade significantly.
*NOTE: It is suggested that you use the GPL-1200 as the primary connection to the
Network Device, however the GPL-1200 can be replaced by another G.hn
Powerline Adapter.
2. Connect the GPL-1200 to a Network Device with an Ethernet (RJ-45) cable.
(Wait 10 seconds for the Network Indicator to light up GREEN, which
indicates a good connection. A flashing GREEN light indicates that the device
has a good connection and is also sending data).

(C) Adding to an Existing G.hn Network
3. Plug the GPL-1200WAC into the power outlet closest to the location you want to
add wireless and/or near an Internet-Enabled Device you would like to directly
connect to the adapter. The PLC Indicator should light up.
4. Optionally, to add an Internet-Enabled Device, directly connect the GPL-
1200WAC to the Internet-Enabled Device with an Ethernet cable. (The Network
Indicator on the GPL-1200 and the LAN Indicator of the GPL-
1200WAC should both be GREEN representing a strong connection).
(D)
Security Setup
NOTE: G.hn Adapters will automatically “pair” in “non-secure” mode. It is highly
recommended to follow Step 5 to create a secure connection.
5. Press the “Config” Button of a GPL-1200 in the existing network for 2 seconds. You will
see the Security Indicator start flashing GREEN. Within two minutes, press the “PLC
Sync” Button on the GPL-1200WAC for 2 seconds until you see the Security Indicator
start flashing GREEN.(When the adapters are successfully paired and secured
with a strong connection the GPL-1200’s Connection Indicator and Security
Indicator will be solid GREEN and the GPL-1200WAC’s PLC Indicator and
Security Indicator will be solid GREEN.)
6. Repeat Steps 3 to 5 to add additional adapters/devices.

9
(E) Connecting Your WiFi Devices to the New GPL-
1200WAC
Access Point
7. For some devices (E.g. laptops, cameras, set-top-boxes, etc.) wireless
connectivity can be done via WPS (Wireless Protected Setup). WPS allows you to
simply connect devices to the new Access Point without entering a
username/password manually. To do this, please follow the instructions in
Section F below.
8. You have created a new Internet Access Point and it is now active and ready to
use! To connect your WiFi devices to your new GPL-1200WAC WiFi Access Point,
select the GPL-1200WAC Access Point using your WiFi device’s standard network
list. The Network Name (SSID) and Password (WiFi Key) can be found on the
bottom of the GPL-1200WAC.
9. Go to Section G.
(F) Setup of Wireless Devices via WPS
(WiFi Protected Setup)
10. Press and hold the “WPS” Button for more than 2 seconds on the GPL-1200WAC
to activate its WPS. The GPL-1200WAC’s WiFi Indicators should flash
to indicate a WPS connection is in progress.
11. Within two minutes, press the “WPS” Button (often the WPS/Reset Button) on
your remote Internet-Enabled Devices to activate WPS.
12. The devices will establish a secure connection.

(G) You Have Successfully Installed Your G.hn Powerline
Adapter with WiFi!
(H) Troubleshooting
The following information should help you diagnose basic setup or installation problems.
1) SECURITY Indicator is OFF: The SECURITY Indicator is off when the Powerline Adapter
is paired in “non-secure” mode to the G.hn Network. It is
optional to pair the device in “secure mode.” To pair the
device in “secure mode," please refer to Section D, Step
5.
2) LAN Indicator is OFF: The LAN Indicator is off when the
Powerline Adapter does not have a device directly
connected to its Ethernet Port. If there is a device
connected and if the LAN Indicator is off, please check
that the Ethernet port of the Powerline Adapter is
connected firmly to the Ethernet port of the device. You
can also check the condition of the Ethernet cable by
using another Ethernet cable to test if the indicator turns
on.
3) WiFi Indicators are OFF: The WiFi Indicators are off
when the WiFi is not enabled. You can turn on both indicators, (i.e. enable WiFi) by
pressing the “WiFi” Button on the front of the device. You can also login to the
GPL-1200WAC Web Interface and enable WiFi (5GHz only). Please refer to section 6.5
of the User Manual for additional details.

4) PLC Indicator is OFF: The PLC Indicator is off when the Powerline Adapter is not
paired to the G.hn Network. If this indicator is off, then plug both Powerline Adapters
that you are attempting to pair into power outlets that are located within the same
room. All of the indicators of the device should blink (approx. 10 seconds), and
the PLC Indicator should light up. If the PLC Indicator does not light up, it may indicate
the existing G.hn network is secure and you have to pair the GPL-1200WAC to it in
“secure mode.” To do so, press the “Config" Button on the GPL-1200 for 2 seconds
(Holding for more than 4 seconds will clear the security key and require a re-pairing).
Within 2 minutes, press the "PLC Sync" Button on the GPL-1200WAC for 2 seconds. The
PLC Indicator will then light up GREEN. Afterwards, you can plug the units back into
their original location.
* If you have tried all of the above and are still experiencing problems, you can reset all
devices to factory default by pushing the “Reset” Button on the GPL-1200WAC for more
than 10 seconds AND the “Config” Button on the GPL-1200 for 10 seconds.

Chapter 5 wireless System and Network Setup
5.1 Connect to power line access point by web
browser
GPL-1200WAC supports two kinds of management IP.
(1) DHCP client, which gets a dynamic IP address from the Modem/Broadband
Router/Home Gateway that it is connected to by default.
(2) Static IP, 192.168.0.5 by default, which can be configurable in the web UI.
Before you can connect to the power line access point and start configuration procedures,
your computer must be able to get an IP address automatically (dynamic IP address).
GPL-1200WAC gets a dynamic IP address from Modem/Broadband Router/Home Gateway
that it is connected to by default. However, the current IP info of GPL-1200WAC would be
displayed at the Modem/Broadcom Router/Home Gateway.
Also, the static IP of GPL-1200WAC can be accessed by the default static IP address of
192.168.0.5, subnet mask 255.255.255.0. Change your PC’s static IP address to
192.168.0.100, subnet mask 255.255.255.0 for accessing web UI management.

15
5.2 Connecting to Web Management Interface
All functions and settings for the Wi-Fi AP of GPL-1200WAC must be configured via the
web management interface. Please start your web browser, and input ‘192.168.0.5’in the
address bar, then press the ‘Enter’ key. The following will be displayed:
Please input user name and password in their respective fields, default user name is
‘root’, and default password is ‘12345’, then press the Login button, to view the web
management interface of this access point.
NOTE: If you can’t see the web management interface, and you’re
being prompted to input user name and password again, it means
you didn’t input username and password correctly.
