这个属于IP地址出错了,设置方法如下:
①点击任务栏的网络图标→打开网络和共享中心

②网络和共享中心→更改设配器设置

③右键点击网络连接(有线的是本地连接,无线的是无线连接)→属性

④Internet 协议版本 4(TCP、IPv4)→属性

⑤这里是最关键的一步,如果使用错误的IP地址,就会不能上网,不妨改成自动获取IP地址→确定(如果是单位的局域网,则需要根据实际情况填写IP地址等讯息)

⑥如果网络连接之前是好的,切换网络之后异常了,不妨清理一下DNS缓存。
开始→运行→输入:CMD 按回车键,打开命令提示符窗口,再输入:

ipconfig /flushdns 回车执行命令,重建本地DNS缓存。
