ping外网测速不正常!!!

问题描述：

以下是测试本机到外网的连接状况。请观察time的数值，单位是ms(毫秒)。
空闲时time值应为10ms~20ms。若time=100ms以上说明下载占用了较多带宽。
若每隔几行就出现Request time out说明传输不连续，网络软件容易掉线。

以下是测试本机到路由器的连接状况。每行都应是一样的，time值恒定不变。
由于局域网电脑是通过路由器再连接到外网，因此若您的上网出了问题，那么
首先要检查本机到路由器的连接有无问题。这就是ping路由器IP的作用。

问题解答：

运行超时，这是网络不通呀，你用的是不是光纤上网的，你说的情况既使在能PING通的情况下，线路质量也很差，需要查一下外线，或网线。
