The 3-Port Router's Front Panel LEDs

The LAN Indicators
Power Green. The Power LED lights up green when the Router is
powered on.
Link/Act Green. The Link/Act LED serves two purposes. If the LED
is continuously lit, the Router is successfully connected to
a device through the corresponding RJ-45 port (1, 2, or 3). If
the LED flickers, then that port is sending or receiving data
to and from the network.
Full/Col Green. The Full/Col LED also serves two purposes. If this
LED is continuously lit, the connection made through the
corresponding port is successfully running in Full Duplex
mode. If the LED is flickering, the connection is experien-
cing collisions. Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with
your connection. See the Troubleshooting section if you
have problems.
100 Orange. The 100 LED lights up when a successful 100Mbps
connection is made through the corresponding port. If this
LED does not light up, then your connection speed is
10 Mbps.
