Has there been a power cut/network outage in the Dealership? Has your local IT Dept. changed anything? Test to see if everyone else has network.

Check the network cable is properly plugged into the kiosk/wall and hasn't been physically damaged. (Test another network socket/Network Cable)

Using the keys provided, unlock the rear bottom panel of the kiosk, on the left-hand side you will see the PC unit. Locate the network cable adapter plugged into it and check to see if there are link lights (Green/Amber)on it.

If the network adapter connected to the PC Unit does not have a Link Light, unplug and connect the network cable from the Wall/Floor socket directly to the PC.
