ADSL Link LED Is Blinking Amber
If your ADSL link LED is blinking amber, then your modem router is attempting to make an
ADSL connection with the service provider. The LED should turn 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 should be 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 ADSL 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 should be 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.
Internet LED is Red
If the Internet LED is red, the device was unable to connect to the Internet. Verify the following:
• Check that your log-in credentials are correct, or that the information you entered on the Basic
Settings screen is correct.
• Check with your ISP to verify that the Multiplexing method, VPI, and VCI settings on the
ADSL settings screen are correct.
• Check if your ISP has a problem—it may not be the router that cannot connect to the Internet
but your ISP that cannot provide an Internet connection.
