ping 的是路由器吧? 如果所有电脑ping 路由器或者互ping都是这样,那么有几种情况,主线路是否老化了,内网接线是否有环路,内网是否有病毒攻击。。。前面的原因都很好排除解决,如果内网有病毒攻击的话,很难找到攻击源,一台台电脑还原也不大可能,还原了以后也有可能出现,不可能又还原吧?现在有个巡路免疫网络的,专门做内网安全管理,听说还不错,你可以去了解了解!

不是网卡的原因。两个原因,你查查。1、有一台计算机有arp病毒。2、有人用p2p终结者之类的软件

你这台电脑ping网关明显有掉包,建议更换网卡(当然网线接头也有可能,但网卡故障的概率很高)
另外,因为你是多台电脑共享上网,所以其它人看p2p或是bt类下载都会影响局域网的其它主机。所以在网关上需要进行设置,最好是直接用有qos功能的路由器进行设置(当然也有可能已经有人进行了限速设置将你的ip限速了)
