一会up  一会down到底正常不

微信扫一扫，阅读更方便^_^

涵哥

这个log很明显，就是端口4连接瞬间up，然后又断开连接，这样循环
建议如下：
换根线，确保物理连接正常
如果不行再说一下

问题是端口4我多没插网线

a16060

路由器的背面用插了1号和2号两个口，再者就是光猫出来连着的WAN口

xxoo2008

这个 eth4 并不是指你的4号lan口,根据华硕的技术人员告诉我的,还有 eth0那些的,他是指内部的端口号,包括wan口算一个,所以你这个 eth4 应该是指1或者2号口,反正我的 eth1其实是指2号口, eth2反而是1号口

如何才能具体区分那？我刚才除了光猫和路由器连着，其他直插网线连接的设备一个多没开，按他提示一会断开一会连接我的无线上网应该有问题，可我各种无线设备上网多好好的

先按版主说的,换根网线,这个估计是指你光猫和路由连接这根线

我这跟网线是我新买的6类网线，据说比5类好不少

确实如你说的，换上RT-AC86U自带的网线后好像吗没有问题了，
