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.

100Orange. 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.

The WAN Indicators
Link	Green. The Link LED lights up when a successful connec-
	tion is made between the Router and your broadband device
	or network.
Act	Green. The Act LED flickers when the Router is sending or
	receiving data over the broadband WAN port.
Diag	Red. The Diag LED lights up when the Router goes through
	its self-diagnostic mode. It will turn off upon successful
	completion of the diagnosis.
