The perfect complement for a Wi-Fi connection
Powerline adapters are the ideal way of creating a home network or complementing an
existing Wi-Fi connection.
y providing a secure high speed connection and great service quality, Powerlines allow
you to watch Standard and High Definition (HD) movies as well as play online games
without interruption or pixilation; share photos, music and other media stored on a PC or
compatible storage device anywhere in your home.
Powerline Adapters will help you reach those areas of your home where Wi-Fi signal is
either too weak or cannot reach.
Other usages of Powerline adapters include IP-CCtv surveillance cameras, setting up an
office network without the need to add more wires or rewire if you change your office
configuration.

settings.
Ethernet Port:
PowerLines use an Ethernet port to connect through an Ethernet cable to the device you
wish to add to your network. One end of the Ethernet cable is connected to the Powerline
adapter, while the other end is connected to your device.
Front and rear plugs
Comtrend Powerline adapters are the first ones in the UK market to bring a fully S1363
certified female plug; so choosing a Comtrend Powerline PG9020 means you can still
safely use your electrical outlet.

How to install the PowerGrid 9020
Comtrend’s PG9020 starter kit, supplied in pairs, comes ready to use; the Powerlines
adapters are paired in our factory so they will recognize each other, which makes setup
this easy:
1. Plug both PG9020 adapters into an electrical socket
a. One next your router (or modem)
b. One next to the device you will connect to your network
2. The STATUS LED on both PG9020 will light up RED
3. When the STATUS LEDs are both green the PG9020 are ready to use
Pick the PG9020 adapter with a serial number ending with the letter “A”. The serial
number can be found on the label at the back of the adapter. This is the Access Point (AP).
Connect the AP to your router with an Ethernet cable, as shown here.
Connect the other PG9020 to your Computer, Game Console, Set Top ox or other network
device using an Ethernet cable. This is the End Point (EP).

5
Shortly, you will see the Ethernet LED blinking; this indicates that there is data traffic
going through the PG9020. You are now ready to start using your network.
How to use a power strip with the PG9020
If you are planning to use a power strip we recommend that you plug the power strip in to
the Powerline and not the Powerline into the power strip. If you must plug your adapter
into a power strip, we suggest you use a basic power strip as the more advanced ones have
a filter that can interfere with the Powerline signal.

6
How to add a new Powerline to your existing network
Comtrend Powerline pairs are paired in the factory for your convenience and security.
However if you need to add more adapters to your existing network you will need to
follow some easy steps in order to keep your network secure. The following procedure
applies to PowerLine models (DH10, DH10PF, PG902 & PG9020).
MAKE SURE THAT ALL OF YOUR POWERLINES ARE CONNECTE TO THE MAINS.
NOTE: If you performed a factory reset on the AP
adapter (see step 2), it is now an EP adapter. In
this case, you will need to assign it as an AP (see
FAQ on pg. 8).
Step 1: Identify the current AP
(access point) adapter. From
your current adapters the one
with the AP LED in green will be
the AP adapter.
Step 2: Reset the new Adapter to
its factory settings: this is to
make sure your new adapter is
set as an EP (end point). Press
the CONFIG/RESET button for 10
seconds. All LEDs will turn OFF
and the STATUS LED will be RED.

7
You have now added your NEW EP adapter to your network.
Repeat the same steps for each new adapter you want to add to your network.
Step 3: On your AP adapter
(Step 1), press the
CONFIG/RESET button until the
AP LED starts blinking.
Step 4: On the NEW EP adapter you are
adding to your network (step 2), press
the CONFIG/RESET button until the AP
LED starts flashing. The NEW EP adapter
AP LED will flash 3 times and the STATUS
LED will turn ON.
Wait until the AP LED on the AP adapter
(step 1) stops blinking.

How to understand the STATUS LE colours
The STATUS LED 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 STATUS LED indicator will vary its colour depending on the estimated speed of the
Powerline connection. The speed is measured in Megabytes Per Second (Mbps).
Colour Information
RED The current connection is less than 4Mbps, normal internet activities are
possible but the Powerline is unable to transmit either Standard Movies
or High Definition (HD) Movies
ORANGE The current connection is greater than 4Mbps and less than 10Mbps,
normal internet activities are possible and the network is able to
transmit a single Standard Movie but not an HD Movie.
GREEN The current connection is greater than 10Mbps; the Powerline is capable
of transmitting Standard and HD Movies as well as normal internet
activities.
NOTE: If the HDTV video bandwidth is lower than 10Mbps, it may be possible to
stream the video with an ORANGE STATUS LED in some cases.
Frequently Asked Questions
This Powerline adapter has been designed to be a reliable and easy to use to create or
extend an existing home network. However, should you experience any problems, please
refer to the list below to aid in troubleshooting.
1. How do I convert an AP into an EP?
• Make sure the Powerline adapter is plugged directly into the electrical outlet and
that it is powered on.
• Do a factory reset (see Step 2 on pg. 6 for the Factory Reset procedure).
2. How do I convert an EP into an AP?
• Make sure the Powerline adapter is plugged directly into the electrical outlet and
that it is powered on.
• Press CONFIG/RESET button until its AP/ST Y LED starts blinking.
• Wait until configuration period finishes (30 seconds). At that point the adapter
has been designated as a Fixed AP with an auto generated Network ID and
Encryption key and its AP/ST Y LED lights GREEN.

3. S TV video is not streaming:
• Check the STATUS indicator LED in the adapter connected to the ST .
• If the indicator is RED this means that the PLC link is not able to play an SDTV
streaming.
• Try to reposition the adapter into another outlet in order to obtain an ORANGE
or GREEN indication.
• If the indicator is ORANGE or GREEN, it should now be able to play an SDTV
video. Verify this by confirming that the STATUS indicator LED is blinking when
the video is running. This means that there is activity in the Ethernet connector.
• If the LED is not blinking, check that the Ethernet cable is correctly connected.
• If the LED is blinking and there is still no video streaming, check the settings in
devices connected to the PLC adapters (ST , DSL router, PC, video server, etc.).
4. There is more than one AP in the network because configuration protocol
did not finish correctly:
• In order to work properly your network can only have one Fixed AP unit. Verify
that this is the case by examining the AP/ST Y LED for all adapters
• If there is more than one AP, it means that key exchange process has failed.
• Perform a factory reset on the adapter you DO NOT wish to be designated as an
AP (see Step 2 on page 6 for the Factory Reset procedure).
• Repeat network configuration procedure again (page 6).
• If the configuration procedure has again failed, it is possible the adapters are
using different forms of encryption (crypto mode).
o To eliminate this as a possibility;
o perform a factory reset on all adapters
o choose the adapter you will like to act as an AP (we recommend the one
connected to your modem/router)
o Press CONFIG/RESET button until its AP/ST Y LED starts blinking.
o Wait until configuration period finishes (30 seconds). At that point the
adapter has been designated as a Fixed AP with an auto generated
Network ID and Encryption key and its AP/ST Y LED lights GREEN.
o Follow the steps on page 10
5. H TV video is not streaming:
• Check the status indicator LED in the adapter connected to the set top box (ST ).
• If the indicator is RED or ORANGE this means that the Powerline link is not able
to stream HDTV.
• Try to reposition the adapter in another outlet in order to obtain a GREEN
indication.
• If the indicator is GREEN, it should now be able to play a HDTV video. Verify this
by confirming that the STATUS indicator LED is blinking when the video is
running. This means that there is activity in the Ethernet connector.

10
• If the LED is not blinking check that the Ethernet cables are correctly connected.
• If the LED is blinking and there is still no video streaming, check the settings in
devices connected to Powerline adapters (ST , DSL router, PC, video server, etc.).
NOTE: If the HDTV video bandwidth is lower than 10Mbps, it may be possible to
stream the video with an ORANGE STATUS LED in some cases.
6. My Powerline Adapters don't fit into the plug socket
• Your Powerline Adapters might not fit because the sockets are too close to the
floor or are in the skirting board.
• The easiest way around this is to use a trailing power strip, and plug the Adapter
into the strip. Please make sure that the strip is not an anti-surge adapter strip.
7. What if the house next door has Powerline Adapters as well?
• Each pair of Powerline Adapters has its own unique security key. This means
that your connection is secure and cannot be confused with anyone else's.
8. Is it safe to leave the Powerline Adapters on all the time - is there any
danger of overheating?
• Powerline Adapters are CE certified and completely safe to leave plugged in all
the time. They may become slightly warm in use - this is perfectly normal.
However, you may wish to put them into standby when not in use.
9. How much power do Powerline Adapters use, and how much do they cost
each month in electricity?
• The PG9020 Adapters use 3.4Watts when in use and 0.84 Watt in standby. Prices
vary between electricity suppliers.
10. What is the best way to check that my Powerline Adapters are working
properly?
• Your Powerline Adapters are set to work together as a pair, and should work
perfectly out of the box. The best way to test them is to find a double plug socket,
and plug them in next to each other. Often the best place to find a double plug
socket is in your kitchen. Alternatively plug them into a trailing extension strip
(but not an anti-surge strip).
• When plugged in, after 10-40 seconds, the Powerline Adapters will configure
themselves so that each has a green status light, and one of the pair has an
orange AP light.
• oth adapters have green status lights
• If the Powerline Adapters don't configure themselves as above, you need to
follow the reset procedure.

11
• When your Powerline Adapters are connected to a device the Ethernet light
should light up. When you're using the service the Ethernet light will flash. You
may notice that the Status Light on one or both Powerline Adapters changes to
red or orange. This isn't something to worry about if you are not having any
problems with your connection.
