6. Trouble shooting
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.
6.1 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.
6.2 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.
6.3 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.
6.4 Problems Connecting to a Remote Node or ISP
Problem Corrective Action
Can’t connect to ISP. Check section 3.4.12 “Admin Privilege – PPP status”
to verify the line status.
