N300 WiFi ADSL2+ Modem Router (N300RM)

Troubleshoot the Internet Connection

If your modem router is unable to access the Internet, check the ADSL connection, then the

WAN TCP/IP connection.

ADSL Link

If your modem router is unable to access the Internet, first determine whether you have an

ADSL link with the service provider. The state of this connection is indicated with the ADSL

LED.

ADSL Link LED Is Green

If your ADSL link LED is green, then you have a good ADSL connection. You can be

confident that the service provider has connected your line correctly and that your wiring is

correct.

ADSL Link LED Is Blinking Green

If your ADSL link LED is blinking green, then your modem router is attempting to make an

ADSL connection with the service provider. The LED turns green within several minutes.

If the ADSL link LED does not turn green, disconnect all telephones on the line. If this solves

the problem, reconnect the telephones one at a time, being sure to use a microfilter on each

telephone. If the microfilters are connected correctly, you are able to connect all your

telephones.

If disconnecting telephones does not result in a green ADSL link LED, there might be a

problem with your wiring. If the telephone company has tested the DSL signal at your

network interface device (NID), then you might have poor-quality wiring in your house.

ADSL Link LED Is Off

If the ADSL link LED is off, disconnect all telephones on the line. If this solves the problem,

reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If

the microfilters are connected correctly, you are able to connect all your telephones.

If disconnecting telephones does not result in a green ADSL link LED, check for the

following:

• Check that the telephone company has made the connection to your line and tested it.

• Verify that you are connected to the correct telephone line. If you have more than one

phone line, be sure that you are connected to the line with the ADSL service. It might be

necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The

modem router uses pins 2 and 3.
