N150 Wireless ADSL2+ Modem Router DGN1000 User Manual
No Internet Connection
If your router cannot access the Internet, first check the DSL connection, and then check the
WAN TCP/IP connections. See
Figure 54, Front panel LED Icons on page 85 for the location
of the LEDs.
DSL Link
First determine whether you have a DSL link with the service provider. The state of this
connection is indicated by the DSL LED.
DSL Link LED Is Green or Blinking Green
You have a good DSL connection. The service provider has connected your line correctly,
and your wiring is correct.
DSL Link LED Is Blinking Amber
Your wireless modem router is attempting to make a DSL connection with the service
provider. The LED should turn green within several minutes.
If the DSL link 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 on page 13. If you connect the microfilters correctly, you
should be able to connect all your telephones.
If disconnecting telephones does not result in a green DSL 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), you might have poor-quality wiring in your house.
DSL Link 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 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 DSL service. It could be
necessary to use a swapper if your DSL signal is on pins 1 and 4 or the RJ-11 jack. The
wireless modem router uses pins 2 and 3.
