Chapter 4. Troubleshooting
If the ADE-4120 ADSL Firewall 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-4120
Problem Corrective Action
None of the LEDs are
on when you turn on
the ADE-4120
Check the connection between the adapter and the
ADE-4120 . 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-4120 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-4120 . 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 LNK/ACT 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-4120 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-4120 and the
workstations.
