CHAPTER 4: 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 AC 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 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 Ethernet LEDs 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
Check section 3.4.8 “System Status” to verify the line status. Can’t connect to a remote
node or ISP.
In section 3.4.7 “Remote Config”, verify your login name and password
for the remote node.
