Chapter 4. Troubleshooting
If the ADE-4200/ADW-4200 Wireless ADSL Router is not functioning properly, you can refer
first to this chapter for simple troubleshooting before contacting your service provider. This
could save you time and effort but if the symptoms persist, then consult your service provider.
Problems Starting Up the ADE-4200/ADW-4200

None of the LEDs are
on when you turn on
the ADE-4200/ADW-
4200
Check the connection between the adapter and the
ADE-4200/ADW-4200 . 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 ADE-4200/ADW-4200 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 ADE-4200/ADW-4200 . 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 ADE-4200/ADW-
4200 and the station. Make sure you have uninstalled
any software firewall.
Can’t ping any station
on the LAN.
Verify that the IP address and the subnet mask are
consistent between the ADE-4200/ADW-4200 and the
workstations.
