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).
Color
RED
Information
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:
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.

13.6.3.1 Disable Security
When you select ‘Disable’, wireless encryption for the network is disabled.
13.6.3.2 WEP
WEP (Wired Equivalent Privacy) is a common encryption mode, it’s safe enough for home and personal use.
But if you need higher level of security, please consider using WPA encryption (see next Section).
However, some wireless clients don’t support WPA, but only support WEP, so WEP is still a good choice for
you if you have such kind of client in your network environment.
When you select ‘WEP’ as the encryption type, the following will be displayed:
802.1x
Authentication

Key Length
While WEP Encryption is selected.
Click the check box to enable the IEEE 802.1x
authentication function.
There are two types of WEP key length: 64-bit and
128-bit. Using ‘128-bit’ is safer than ’64-bit’, but will
reduce some data transfer performance.
