    宿舍 4 个人，每人 2-3 台设备左右，换了 2 台不同型号的 tp-link 都会出现以下问题


    WIFI 是连着的，但是不能上网。于是我 ping 192.168.1.1 但是也一直超时，需要断开重新连好几次或者重启路由器解决问题，这是偶尔一台电脑或者手机的问题。但是有时会所有设备一起网络受限无连接。很奇怪，求解决办法

    你要看看有没有 arp 欺骗, arp 欺骗会导致网关(路由器)mac 被修改, 换而言是就是有没有电脑中毒.

    * 检查一下路由器的 mac 和电脑显示的网关 mac 是否一致.
    * 命令行 arp -a, 看看有没有不认识的 mac 地址或者 ip 地址.
    * 路由器看看 connected device list, 有没有不认识的设备.

    最后,贵的路由器基本都挺不错的, 我在用思科的企业路由器.
