校园网络使用最基本的地方在于电脑里的“本地连接”,本地连接通常在桌面 校园网络使用及基本故障排除 一、确认计算机网络设备 校园网络使用最基本的地方在于电脑里的“本地连接”，本地连接通常在桌面的右下角显示，因设置的问题无显示的话可以在“控制面板”的“网络连接”中找到，如图: 如果出现无法找到本地连接的状况，有可能是因为电脑的网卡损坏或网卡驱动不正常造成的，请在设备管理器中检查自己的网卡是否正常。 通常在以上图片中的阴影部分显示为计算机的网卡设备，如无法看到该设备或有感叹号等图标显示均为不正常，有以上情况时电脑无法上网。 二、确认本地连接设置及状态(不使用路由器及交换机时) 在校园网络使用中，本地连接应设置为自动获取IP地址及DNS地址，以上设置可以打开本地连接的“属性”在其中的”InternetTCP/IP”中找到，如下图: 本地连接的状态分为，电缆被拔出，受限制和已连接上三种状态。 当显示“电缆被拔出”时，通常有以下几种情况: 1.网络电缆没有插好或者网络电缆已经损坏; 2.你所使用的网络端口没有开通或者已经损坏。 遇到这种情况时，可以先尝试更换网络线，校园网应使用8芯4对的超五类双绞线，如图: 若无法解决，可与网络管理中心联系解决。 当出现网络受限制时，既电脑没有获取到IP地址，为以下几种情况: 1. 网络线部分损坏; 2. 所使用的网络端口部分损坏; 3. 由于特殊原因端口被隔离。 由于网络线及网络端口都由8芯构成，当其中部分线路断路时，电脑可characteristics and duration control requires adequate labour, and establish a reward system, emulation, good team work, life and other logistical support, maintain strong work ethic and sense of responsibility, ensure the successful completion of tasks.
