Manual Setup
Use the topics and procedures below to manually set up your modem.
Understanding ADSL Microfilters
ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to
the telephone lines which create noise in the telephone service. You must use ADSL microfilters to
filter out these signals before they reach your telephone.
If you purchased the modem in a country where a microfilter is not included, you must
acquire one.
ADSL Microfilter
Figure 4
Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
Do not connect the modem to the ADSL line through a microfilter unless the
microfilter is a combination microfilter/splitter specifically designed for this purpose.
Doing so will prevent block your connection to the Internet. If you have any doubts
about this, connect the modem directly to the ADSL line.

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.

•
If the LAN port is lit, but the Internet port is not, 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.
Troubleshooting the Web Management Interface
If you are unable to access themodem’s Web Management interface from your computer check the
following:
•
Check the Ethernet connection between the computer and the modem as described in the
previous section.
•
If your computer is directly connected to the modem, make sure your computer’s IP address is
on the same subnet as the modem. If you are using the recommended addressing scheme, your
computer’s address should be in the range of 192.168.0.2 to 192.168.0.254. Follow the
page 22 to configure your computer.
If your computer’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign an IP address if
the computer cannot reach a DHCP server. These auto-generated addresses are in
the range of 169.254.x.x. If your IP address is in this range, check the connection
from the computer to the modem and reboot your computer.
•
If your modem is connected to your computer via a router, make sure the computer’s IP
address is on the same subnet as the router, and the router is on a different subnet from the
modem. The LAN IP addresses of the modem and router will normally be printed on a label on
the bottom or rear of the unit.
•
•
If your modem’s IP address was changed and you do not know the current IP address, clear the
modem’s configuration to factory defaults. This will set the modem’s IP address to
Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure that the Java applet is loaded.
•
•
Try quitting the browser and launching it again.
Make sure you are using the correct login information. The factory default login name is
admin and the password is password. Make sure that CAPS LOCK is off when entering this
information.

If the modem does not save changes you have made in the Web Management Interface, check the
following:
•
When entering configuration settings, be sure to click the Apply button before moving to
another menu or tab, or your changes are lost.
•
Click the Refresh or Reload button in the Web browser. The changes may have occurred, but
the Web browser may be caching the old configuration.
Troubleshooting the Internet Connection
If your computer is connected to your modem via a router, disconnect the router and directly
connect the computer to the modem. If you now have Internet access, use the documentation that
came with the router to perform re-installation and troubleshooting.
If your modem is unable to access the internet, but your Internet LED is green or blinking green,
you should determine whether the modem is able to obtain an IP address from the ISP. Unless you
have been assigned a static IP address, your modem must request an IP address from the ISP. You
can determine whether the request was successful using the browser interface.
To check the WAN IP address from the browser interface:
3. Under the Maintenance heading, select Modem Status. Check that an IP address is shown for
the ADSL Port. If 0.0.0.0 is shown, your modem has not obtained an IP address from your ISP.
If your modem is unable to obtain an IP address from the ISP, the problem may be one of the
following:
•
Your ISP may require a Multiplexing Method or Virtual Path Identifier/Virtual Channel
Identifier parameter.
Verify with your ISP the Multiplexing Method and parameter value, and update the router’s
ADSL settings accordingly.
•
•
If your ISP requires PPP over Ethernet (PPPoE) or PPP over ATM (PPPOA), check that your
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.

Troubleshooting PPPoE or PPPoA
The PPPoA or PPPoA connection can be debugged as follows:
2. Under the Maintenance heading, select the Diagnostics.
3. Click Run Diagnostic Tests.
4. If all of the steps indicate “OK” then your PPPoE or PPPoA connection is up and working.
If you cannot connect after several minutes, you may be using an incorrect Service Name, User
Name or Password. There also may be a provisioning problem with your ISP.
Unless you connect manually, the modem will not authenticate using PPPoE or PPPoA
until data is transmitted to the network.
Troubleshooting Internet Browsing
If your modem can obtain an IP address but your computer is unable to load any Web pages from
the Internet:
•
Your computer may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the modem’s configuration, reboot
your computer and verify the DNS address as described in the online document that you can
computer manually with DNS addresses, as explained in your operating system
documentation.
•
•
Your computer may not have the modem configured as its TCP/IP modem.
If your computer obtains its information from the modem by DHCP, reboot the computer and
verify the modem address as described in the online document that you can access from
