关于AC87U双电信100M光纤双拨后掉速严重的问题
设备清单：光猫1：华为8245 四口千兆刷原厂固件 包括语音在内 正常使用IP地址：192.168.1.1
光猫2：华为8245 四口千兆刷原厂固件 正常使用IP地址：192.168.2.1
路由： 华硕RT-AC87U 固件：梅林380.57 IP地址：10.0.1.1
网线： 所有设备之间全部使用 包尔星克 成品 七类圆线
----------------------------------------------------------------------------------------------------------------------
从加入第二条电信100M光纤之后，使用路由WAN口连接光猫1，进行PPPOE拨号，路由LAN4连接光猫2，PPPOE拨号
经http://www.speedtest.net测速，可以稳定在210M到217M之间的下行带宽，进行迅雷多线程下载，可以稳定在25M+的
下载速度。
经过几天的使用期（期间未动过路由），突然有一天，发现测速的时候丢速严重，speedtest.net测速的时候，丢速很厉害
非常的不稳定，但是只要关掉其中一个光猫，就可以稳定测速，两个光纤，每一个单测都可以达到107左右的下行带宽，双光猫
只要一同时开，马上就会出现丢速，掉速的现象。
经联系客服，重新刷了官方最新固件，刚刷完固件后，测速可以达到两条光纤的正常下载速度，能跑满两条下行带宽，但是
路由运行时间只要长一点（半小时到一小时左右），丢速，掉速现象又会出现。
后来经过多次重刷固件（官方最新固件或是梅林的最新固件），发现一个很奇怪的现象，每次重刷后，可以稳定运行一小会儿，
只要路由运行时间稍长一点，老问题就会出现。

固件问题？ AC87U硬件问题？
还是AC87U的吞吐量不行？ speedtest测速异常的时候，迅雷多线程下载的速度是多少？ 迪安 发表于 2016-2-15 15:10

这是我把两线从救援模式恢复到负载均衡模式后的记录然后进行测速 不正常，但是记录里并未有新记录 迪安 发表于 2016-2-15 15:10

um~，截张System Log--Routing Table图看一看呢 每次都是过一阵子之后才会这样，所以涵哥想问一下
1.你单线的时候，会不会过一阵子也这样？
2，你测速有变化的时候，有没有换个测速网站试试，最好是电信的，结果如何？
3.测速掉速的时候，你的实际下载速度有多少？可以用BT下载工具试一试
4.不排除固件的问题，所以你可以换一个固件试一下，上一版也可以
5.不排除线路问题，你可以尝试使用其他路由器试一试，对比一下 我觉得小型路由的负载均衡算法肯定是有点问题的，否则双线路的企业级路由如何有市场？能充分用好双线路，最好用规则好两条线路是哪台终端使用，用救援模式加终端规划走线路比较合理和稳定。楼主尝试一下，把BT类的终端走一条线，无线或者要求响应的走另外一条线，或许就能充分和稳定使用了。
