Action
• Verify that the Barricade and attached device are
powered on.
• Be sure the cable is plugged into both the Barricade
and corresponding device.
• Verify that the proper cable type is used and its length
does not exceed specified limits.
• Be sure that the network interface on the attached
device is configured for the proper communication
speed and duplex mode.
• Check the adapter on the attached device and cable
connections for possible defects. Replace the defective
adapter or cable if necessary.
• If the Sync indicator on the Barricade is off, make sure
the Barricade's DSL port is connected to your ADSL
service provider's incoming line via an RJ-11 wall
socket or splitter.
• Check the ADSL cable to be sure it is not defective.
• Be sure you are using the correct login name and
password for your ISP.
• Verify that VPI and VCI are set to values provided by
your ISP.
• Reboot the Barricade, and see if you can establish a
remote connection. If you still cannot, check with your
ISP to ensure that the connection parameters are
correct, and that the external ADSL line is functioning
properly.
