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.
Problems Connecting to a Remote Node or ISP
Problem Corrective Action
Can’t connect to ISP.
Check section 3.4.1.3 “Status – PPP status” to verify the line
status.
