Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should check the ADSL connection, then the
WAN TCP/IP connection.
ADSL link
If your router is unable to access the Internet, you should first determine whether you have an
ADSL link with the service provider. The state of this connection is indicated with the WAN LED.
WAN LED Green or Blinking Green
If your WAN LED is green or blinking 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.
WAN LED Blinking Yellow
If your WAN LED is blinking yellow, then your router is attempting to make an ADSL connection
with the service provider. The LED should turn green within several minutes.
If the WAN LED does not turn green, disconnect all telephones on the line. If this solves the
problem, reconnect the telephones one at a time, being careful to 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 WAN LED, there may be a problem with
your wiring. If the telephone company has tested the ADSL signal at your Network Interface
Device (NID), then you may have poor quality wiring in your house.
WAN LED Off
If the WAN LED is off, disconnect all telephones on the line. If this solves the problem, reconnect
the telephones one at a time, being careful to use a microfilter on each telephone. If the microfilters
are connected correctly, you should be able to connect all your telephones.
