| Loss of network connectivity can manifest itself in different ways: logon failure due to inaccessible domain controller, no internet connection, mail server inaccessible, network resources inaccessible etc. Computer networking is structured in so called layers (https://en.wikipedia.org/wiki/OSI_model), where ** layer 1 ** is the physical layer, which is practically the physical connection, a cable. Although you can't trace completely the whole physical route, at least you can first check the connection of your device to the network socket via a UTP cable, provided you are connected by a cable to the network. If you notice that your device has no network connectivity (see "Check connectivity" ) __**check the cable first**.__ | Computer networking is structured in so called layers (https://en.wikipedia.org/wiki/OSI_model), where ** layer 1 ** is the physical layer, which is practically the physical connection, a cable.
