有时候打开网页很慢或者直接打不开，重启路由器能好用一会儿。经常这样，也不是局域网ARP攻击，到底是怎么回事？
一下是路由器日志：

大量掉包啊拜托
硬件问题
看看网线质量、网线接头、路由器硬件、电话线质量、电话线接头
网线太长也会这样，超过100米后电信号微弱了
楼上那个说电压的事的，也很有道理
总之你要查硬件故障了，替换法
tcp/ip属性里设置一下IP地址，例如：一个设192.168.1.110，另一个不能设一样的，可设为192.168.1.111，子网都是一样的255.255.255.0，默认网关设一样的，192.168.1.1，指定一下DNS，这个要查你目前使用的网络的IP地址，上网能查到。路由里可以把DHCP服务关闭，网络参数里的WAN口可以设置自动连接。
首先 重启路由后正常 可以排除你硬件的问题！那么就是你机子本身的问题！
我是用优化大师把不用的服务全部关掉！
特别是开机速度优化 除了防火墙和输入法其他的都别开机自运行！
现在我这里很快很正常 试试 可能可以帮到你
