Troubleshooting
If the ADSL Router is not functioning properly, you can refer first to this chapter for simple
troubleshooting before contacting your service provider. This could save your time and effort but if the
symptoms persist, then consult your service provider.
Problems Starting Up the ADSL Router
Problem Corrective Action
None of the LEDs are
on when you turn on
the ADSL Router. Check the connection between the adapter and the ADSL
Router. If the error persists, you may have a hardware
problem. In this case, you should contact technical support.
Problems with the WAN Interface
Problem Corrective Action
Initialization of the
PVC connection failed. Ensure that the cable is connected properly from the ADSL
port to the wall jack. The ADSL SYN LED on the front panel
of the ADSL Router should be on. Check that your VPI, VCI,
type of encapsulation and type of multiplexing settings are
the same as what you collected from your telephone company
and ISP.
Reboot the ADSL Router. If you still have problems, you
may need to verify these variables with the telephone
company and/or ISP.
Problems with the LAN Interface
Problem Corrective Action
Check the LAN LNK LED on the front panel. The LED
should be on for a port that has a station connected. If it is
off, check the cables between your ADSL Router and the
station. Can’t ping any station
on the LAN.
Verify that the IP address and the subnet mask are consistent
between the ADSL Router and the workstations.
