DSL LED Is Blinking White
If the DSL LED is blinking white , your modem router is attempting to make a DSL connection with
the service provider. If the modem router establishes a DSL connection, the DSL LED turns solid white.
This connection process generally lasts several minutes.
If the DSL LED does not turn solid white, 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 can connect all your telephones.
If disconnecting telephones does not result in a solid white DSL LED, a problem with your wiring might
exist. If the telephone company tested the DSL signal at your network interface device (NID), then wiring
in your house might be of poor quality.
DSL LED Is Off or Internet LED Is Off
If the DSL LED is off , the Internet LED is off , or both are 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 can connect all your telephones.
If disconnecting telephones does not result in a blinking white or solid white DSL LED, check the following:
• Check to see that the telephone company made the connection to your line and tested it.
• Verify that you are connected to the correct telephone line. If more than one phone line is installed,
be sure that you are connected to the line with the DSL service. It might be necessary to use a swapper
if your DSL signal is on pins 1 and 4 or the RJ-11 jack. The modem router uses pins 2 and 3.
Internet LED Is Off
If the Internet LED is off , the modem router cannot connect to the Internet. Verify the following:
• Check to see that your login credentials are correct or that the information you entered for the ISP
connection is correct. For more information, see one of the following sections:

• Manually Set Up a Cable or Fiber Internet Connection on page 73
• Check to see if your ISP is experiencing a problem—it might not be that the modem router cannot
connect to the Internet, but rather that your ISP cannot provide an Internet connection.
Obtain an Internet IP Address
If the modem router cannot access the Internet but the Internet LED lights solid white, see if the
modem router can obtain an Internet IP address from the ISP. Unless the modem router is assigned a
