请把网线交换用一下，如果另一台电脑也这样，可能是网线问题或网线和路由及电脑接触不好，如果还是这样，请检查18.2的那台电脑网络设置是否正确及系统问题（　有的路由有一个iptv接口，如果是这样的话，你也需要在路由设置里改动一下）

无线wan口 连 有线（主）lan口 1.先断开无线和有线路由器之间的连接（如果没连就不用断了，这个很重要） 2.使用有线或无线连接无线路由器192.168.1.1登陆 网络参数-》lan口设置-》ip地址设置为:192.168.2.1->保存 wan口地址-》wan口连接类型：设置成“动态ip”-》保存 系统工具-》重启路由器 3.无线wan口连接有线lan口 注： tp-link的默认设置 登陆是192.168.1.1，开启dhcp， 所以要更改其中一个的lan口ip，以免冲突 2）无线路由器的wan口设置为动态ip，它的wan口连接在有线的lan口，（有线路 由器开启的dhcp），直接从有线路由器获取ip地址。 3）以后再想登陆无线路由器时要使用192.168.2.1才可以
