1.3 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).

RED
The current connection has standard quality, normal Internet
activities ex. 20Mbps 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 20Mbps 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.

1.4 Point-to-Point Network
CASE 1: Estimated throughput is less than 20 Mbps. The PLC channel is not able to transmit an
SDTV channel. The COVERAGE LED will be RED as shown in the following figure:
CASE 2: Estimated throughput is greater than 20 Mbps but less than 40 Mbps. The PLC channel is
able to transmit an SDTV channel, but not two SDTV channels simultaneously or one HDTV channel.
The COVERAGE LED will be ORANGE as shown in the following figure:
CASE 3: Estimated throughput is greater than 10 Mbps. The PLC channel is able to play at least two
SDTV channels or 1 HDTV. The COVERAGE LED will be GREEN as shown here:

9
1.5 Point to Multipoint Network
In the case where the PLC network is composed of three or more adapters, similar situations could arise as
with a point-to-point network.
CASE 1: The COVERAGE LED in G.hn adapter 2 and G.hn adapter 3 will show the estimated level of
the PLC link receiving from G.hn adapter 1.
CASE 2: The COVERAGE LED in G.hn adapter 1 will show the estimated level of the PLC link from
which it is receiving the most amount of traffic at any given time. For example, if G.hn adapter 1 is
receiving traffic at 50Mbps from G.hn adapter 2 and is receiving 25Mbps from G.hn adapter 3, the
COVERAGE LED will show the level with reference to the G.hn adapter 2 link, as shown in the following
figure.

Chapter 2 Log In Procedure
2.1 Configure 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 XP. 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 domain of 192.168.0.x (5<x<255) with subnet mask of
255.255.255.0. The screen should now display as below.
STEP 4: Click OK to submit these settings.

11
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.
Authentication Password: admin
Click OK to continue.
Note:
The Factory Reset password is: betera

4.1 IP config
In the IP configuration tab of one G.hn node, the IPv4 and IPv6 settings can be read and changed.
IPv4 subsection:
DHCPv4 enabled: in the case of choosing ”NO" IP configuration in the following parameters, the
IPv4 Address, Subnet Mask, Default Gateway and DNS should be configured; fill these fields in. In
the case of choosing “YES” they will be filled automatically when configuration is received from the
DHCPv4 server.
IPv4 address/netmask: IPv4 address / netmask of this device.
Default Gateway: IPv4 gateway to connect the device to other LAN segments.
DNS: Domain Name Server IP (IPV4).
Additional address #1/2: additional fixed IPv4 addresses that will always be configured at boot
time.
IPv6 subsection:
DCHPv6 enabled: in the case of choosing ”NO" IP configuration in the following parameters, the
IPv6 Address, prefix, Default Gateway and DNS should be configured; fill these fields in. In the case
of choosing “YES” they will be filled automatically when configuration is received from the DHCPv6
server.
IPv6 Address / prefix: IPv6 address / prefix of the device to read the node's DHCPv6 address in
case the DHCPv6 is enabled.
Default Gateway: IPv6 gateway to connect the node to other LAN segments.
DNS: Domain Name Server IP (IPV6).
Additional address #1/2/3/4: additional fixed IPv6 addresses that will always be configured at
boot time.
IPv6 Link-Local Address: to read the node's Link Local address.
IPv6 SLAAC address: IPv6 address, automatically obtained by means of the SLAAC mechanism.
NTPv4/v6 subsection:
NTPv4/v6 client enabled: Enable/disable NTP client.

Chapter 7 Multicast Interface
7.1 MCAST Configuration
In the MCAST Configuration tab of "My Network", IGMP snooping and MLD features can be enabled or
disabled. Also, IGMP multicast IP addresses ranges which the G.hn PLC network will sniff; can be
configured.
IGMP Snooping: Enable or Disable.
MLD Snooping: Enable or Disable.
IGMP/MLD broadcast report (allowed): set to NO for enabling reports dropping until the video
source is detected, this is a recommended setting when IGMP/MLD is enabled. Set to YES for
broadcasting reports until the video source is detected; this implies the multicast video stream is
sent as broadcast and it is the recommended state when IGMP/MLD is disabled.
IGMP Multicast ranges configuration: 4 multicast IP address ranges can be configured defining the
minimum and maximum IP addresses of each range. Only multicast traffic within these ranges will be
processed.
