关于路由CL掉线的问题，各位帮我！
这两天， 我的CL路由出现这样一个问题，经常能PING通网关，但就是上不网，重启一下路由器，刚开始的时候，网关和外网都能上网，但到不了一分钟，外网就PING不通了，
检查外网，没有问题，内网换个交换机，还是没有用，
多重启几次，有时候好能用一两个小时不掉，但一会还掉，
我想问的事，这是什么原因引起，谢谢！ 还有，我们路由信息是这样的，大家看看正常不：

变化一下网卡插槽有可能行，
这个问题我也遇到过coyote daemon.info init: Starting pid 1149, console /dev/tty1: '/sbin/getty'
coyote auth.err getty: tty1: input overrun
和网络相关的看不出来。不过频繁出现的这个信息有问题。
