N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700

No ISP Connection

If your router cannot access the Internet, first check the ADSL connection, and then check
the WAN TCP/IP connections. See
of the LEDs.

ADSL Link

First determine whether you have an ADSL link with the service provider. The state of this
connection is indicated by the DSL LED.
DSL LED Is Green or Blinking Green
You have a good ADSL connection. The service provider has connected your line correctly,
and your wiring is correct.
DSL LED Is Blinking Amber
Your wireless modem router is attempting to make an ADSL connection with the service
provider. The LED should turn green within several minutes.
If the DSL LED does not turn green, disconnect all telephones on the line. If this solves the
problem, reconnect the telephones one at a time and use a microfilter on each telephone as
described in ADSL Microfilters
should be able to connect all your telephones.
If disconnecting telephones does not result in a green DSL LED, there might be a problem
with your wiring. If the telephone company has tested the ADSL signal at your network
interface device (NID), you might have poor-quality wiring in your house.
DSL LED Is Off
First disconnect all telephones on the line. If this solves the problem, reconnect the
telephones one at a time and use a microfilter on each telephone. If the microfilters are
connected correctly, you should be able to connect all your telephones.
If disconnecting telephones does not result in a green DSL 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 could be
necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The
wireless modem router uses pins 2 and 3.
