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 connec-
tion speed is 10 Mbps.
USB The USB LED lights up when the USB
port is successfully connected to a PC,
USB hub, or other USB device.
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.

through its self-diagnostic test during boot-up. It will turn
off upon successful completion of the diagnosis. This LED

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 up, the Router is suc-
cessfully connected to a device through the corre-
sponding RJ-45 port (1, 2, or 3). If the LED flick-
ers, then that port is sending or receiving data to
and from the network.
Full/Col Green. The Full/Col LED also serves two purpos-
es. If this LED is continuously lit up, the connec-
tion made through the corresponding port is suc-
cessfully running in Full Duplex mode. If the
LED is flickering, the connection is experiencing
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.
