Basic
Functioning
After
you
plug
in
the
Powerline
adapter,
the
following
sequence
of
events
should
occur:
1.
When
power
is
first
applied,
verify
that
the
Power
light
is
on.
2.
After
approximately
10
seconds,
check
the
LEDs
on
the
Powerline
adapter.
The
following
should
occur:
c.
The
power
LED
is
solid
green.
a.
The
green
Power
Link
LED
is
lit.

Make
sure
that,
if
power
to
the
AC
power
outlet
is
controlled
by
a
wall
switch,
the
wall
switch
is
in
the
on
position.
Verify
that
the
wall
socket

To
do
this,
disconnect
the

or
a
hairdryer.
If
the
Power

still
does
not
come
on,
and
you
have
confirmed
the
power
outlet
is
live,
you
have
a
hardware
problem
and
should
contact
technical
support.

If
the
power
light
is

light
is
not,
check
the
following:
—
Make
sure
that
power
is
being
provided
to
more
than
one
Powerline
device.
Another
Powerline
device
must
be
installed
for
successful
communication
across
the
Powerline.
—
Verify
that
the
network
password
is
the
same
on
all
devices
in
the
Powerline
network.
z
Ethernet
Light
is
Off
—
Make
sure
that
the
Ethernet
cable
is
plugged
in
properly
at
both

—
Be
sure
that
you
are
using
the
correct
cable
on
the
router
that
the
first
Powerline
adapter
is
connected
to.
When
connecting
the
router’s
Internet
port
to
a
cable
or
DSL
modem,
use
the
cable
that
was
supplied
with
the
cable
or
DSL
modem.
This
cable
could
be
a
standard
straight
‐
through
Ethernet
cable
or
an
Ethernet
crossover
cable.
—
On
the
attached
Ethernet
device
or
network
adapter
card,
check
that
the
Link
light
is
on.
