Troubleshooting
If your ADSL Router is not functioning properly, you can refer first to this chapter for simple
troubleshooting before contacting your service provider or Billion support. This can save you
time and effort but if symptoms persist, consult your service provider.
Problems starting up the router
None of the LEDs
are on when you
turn on the router.
Check the connection between the adapter and the router. If
the error persists, you may have a hardware problem. In this
case you should contact technical support.
You have forgotten
your router login
and/or password
.
Try the default login and password, please refer to Chapter 3.
If this fails, you can restore your router to its factory settings
by holding the Reset button on the back of your router for 6
seconds or more.
Problems with the WAN Interface
Initialization of the
PVC connection
(“linesync”) failed.
Ensure that the telephone cable is connected properly from
the ADSL port to the wall jack. The ADSL LED on the front
panel of the router should be on. Check that your VPI, VCI,
encapsulation type and type of multiplexing settings are the
same as those provided by your ISP. Reboot the router GE. If
you still have problems, you may need to verify these settings
with your ISP.

Frequent loss of
ADSL linesync
(disconnections).
Ensure that all other devices connected to the same
telephone line as your router (e.g. telephones, fax machines,
analogue modems) have a line filter connected between
them and the wall socket (unless you are using a Central
Splitter or Central Filter installed by a qualified and licensed
electrician), and ensure that all line filters are correctly
installed and the right way around. Missing line filters or line
filters installed the wrong way around can cause problems
with your ADSL connection, including causing frequent
disconnections. If you have a back-to-base alarm system you
should contact your security provider for a technician to make
any necessary changes.
Problems with the LAN Interface
Can’t ping any PCs
on the LAN.
Check the Ethernet LEDs on the front panel. The LED should
be on for a port that has a PC connected. If it is off, check the
cables between your router and the PC. Make sure you have
uninstalled any software firewall for troubleshooting.
Verify that the IP address and the subnet mask are consistent
between the router and the workstations.
