Internet / ISP Connection
ADSL link
If your ADSL Modem is unable to access the Internet, you should first determine whether you
have an ADSL link with the service provider. The state of this connection is indicated with the
WAN LED.
WAN LED is Yellow
If your WAN LED is yellow, then you have a good ADSL connection. You can be confident that
the service provider has connected you line correctly and that your wiring is correct.
WAN LED is Blinking
If your WAN LED is blinking then your ADSL Modem is attempting to make an ADSL
connection with the service provider. The LED should stop blinking and stay on within two
minutes.
If the WAN LED does not stay on, 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 return the WAN LED to yellow, 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.
Obtaining a WAN IP Address
If your ADSL Modem is unable to access the internet, and your WAN LED is yellow or
blinking, you should determine whether your ADSL Modem is able to obtain a WAN IP address
from the ISP.
Unless you have been assigned a static IP address, your ADSL 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:
1. Launch your browser and select an external site such as www.netcomm.com.au
2. Access the Main Menu of the ADSL Modem’s configuration at http://192.168.1.1
3. Under the Router menu, check that an IP address is shown for the WAN Port. I If
nothing is shown, your ADSL Modem has not obtained an IP address from your ISP.
If your ADSL Modem is unable to obtain an IP address from the ISP, the problem may be
one of the following:
■ Your ISP may require a login program.
■ Ask your ISP whether they require PPP over Ethernet (PPPoE) or PPP over ATM
(PPPoA) login.
■ If you have selected a login program, you may have incorrectly set the Service Name,
User Name and Password. See “PPPoE or PPPoA”, below.
