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 an ADSL Internet Connection on page 49
• Manually Set Up a VDSL Internet Connection on page 60
• Manually Set Up a Cable or Fiber Internet Connection on page 69
• 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 static IP address, the modem
router requests an IP address from the ISP.You can determine whether the request was successful using the modem
router’s web pages.
