•
Make sure the network settings of the computer are correct.
–
LAN connected computers
must
be configured to obtain an IP address automatically using
DHCP. For more information, see the links in
“Related Documents” on page 43
.
–
Some cable modem services require you to use the MAC address of the computer
registered on the account. If so, in the Router MAC Address section of the Basic Settings
menu, select “Use this Computer’s MAC Address.” Click
Apply
to save your settings.
Restart the network in the correct sequence.
•
Check the router status lights to verify correct router operation
. If the Power light does
not turn solid green within 2 minutes after turning the router on, reset the router according to
the instructions in
“Restoring the Default Password and Configuration Settings” on page 40
.
Checking Basic Router Functions
After you turn on power to the router, check that the following sequence of events has occurred:
1.
When power is first applied, verify that the power light is on (see
“Front Panel” on page 3
for
an illustration).
2.
Verify that the power light turns amber within a few seconds, indicating that the self-test
procedure is running.
3.
After approximately 20 seconds, verify that:
a.
The color of the power light changes to green.
b.
The LAN port lights are lit for any local ports that are connected.
If a port’s light is lit, a link has been established to the connected device. If a LAN port is
connected to a 1000 Mbps device, verify that the port’s light is green. If the port is 10/100
Mbps, the light will be amber.
c.
The Internet port is connected and its light is lit.
4.
If you have enabled WPS to add a wireless client to your network, verify that the push-button
light has started blinking. After ~2 minutes (using the push-button method) or ~4 minutes
(using the PIN method), the WPS push-button light should go off.
If the correct behavior does not occur, check for a remedy from the following list:
•
Power Light is Off.
If the Power and other lights are off (see
“Connecting Your N300
Wireless Gigabit Router” on page 13
), check the following:
–
Make sure that the power cord is properly connected to your router and that the power
adapter is properly connected to a functioning power outlet.
