Troubleshooting 15
If you have just installed the modem and the ADSL LED has never been solid on, check the
following:
• 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 Internet 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.
• 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 may be necessary to
use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The modem uses pins
2 and 3.
• Log in to the modem interface and select ADSL Settings from the Setup section of the main
menu.
• Make sure your login name and account password are correct and the ADSL settings are set to
the values required by your ISP.
If the ADSL light was solid on but is now blinking, try switching off the modem, waiting 30
seconds, and then switching back on again to see if the modem recovers. If the problem persists,
try the following:
• Check with your ISP that your service is not being interrupted.
• If you have recently installed a telephone or other device that uses the telephone lines, make
sure that it is connected to the telephone line via a microfilter.
• Log in to the modem interface, note the modem and ADSL status, run the diagnostics test, and
contact your ISP’s technical support representative. See the User Manual for detailed
information.
LAN or Internet Port LEDs Not On
If either the LAN LED or Internet LED does not light when the Ethernet connection is made,
check the following:
• Make sure that the Ethernet cable connections are secure at the modem and at the connected
router or computer.
• Make sure that power is turned on to the connected router or computer.
