TROUBLESHOOTINGTECHNIQUES If a user says they can’t get on the network, it must be determined what happened. Troubleshooting involves asking many questions that will help pinpoint plugged plugged the cause of the problem. Pertaining to cables-Is the cable in at both ends? Is there a light on the Dongle? Was the cable in before the machine was booted? Obviously the determination is concerned with the root of the problem. Is the problem occurring because of user error, cable failure, or equipment/software failure. Suspecting the cable would lead to a visual inspection of the cable and the end connectors. You would look for wires that were not pushed far enough into the RJ45 to make contact, or had crossed. If those appear to be sound, the next step is using an electronic tester. If the cable passes then check the connections the cable plugs into.
