请问一下，开路由后猫老是掉线，怎么办？

liulzqlzq

    长沙电信4M ADSL宽带，一个账号，允许两台机子以同一个账号同时拨号上网，猫是华为HG520s（有路由功能），路由器是RG100A-AA刷的OpenWrt固件。以前还有一个副账号，那时两台机子需用不同的账号才能同时拨号上网。以前有两个账号的时候，有一段时间试过用HG520s开路由PPPoE拨号上网，很稳定没什么问题。后又改为拨号上网，发现电信将副账号封了，打服务电话才将那个副账号要回来的。今年续费后只一个账号了，而且有时有三台设备同时上网了，于是又想起开路由来了，结果发现麻烦不断。
    开始我还是像以前那样只用HG520s开路由上网，结果不管几台机子哪怕是一台机子在线，不到两分钟猫就会掉线。后面又将RG100A-AA刷OpenWrt后接在猫后面，所有机子都接在RG100A-AA后面，拨号仍由Hg520s完成，情况有所改善，如果只浏览网页的话猫掉线时间稍微延长了点，但只要一看在线视频，一集电视剧下载不到四分之一（大约两分钟不到）猫又掉线了。曾经怀疑HG520s刷的是官方固件，容易被电信控制，于是将其刷成了TP-LINK TD-8901G，情况还是一样。试着将拨号由RG100A-AA完成，情况还是如此。还用过MAC地址欺骗，将猫、路由的MAC地址都改成跟台式电脑一样，还将OpenWrt中那个防网络尖兵的选项也勾选上了，也没有用。现在搞得头都大了，难道只能用电脑拨号？用电脑拨号只能用两台机子，而且BT下载没有速度。请问各位高人，有什么方法解决这个问题？

图中显示你上行的信号低于标准，只有8.0。你这个线路质量是存在问题的。找服务商报障解决，直接说一传东西给人就容易断线，别说你使用路由。说电脑直接拔号，他们会检查线路解决。

谢谢指点！这周末报修去

突然想起以前猫在另一个房间，线路很长，那时接了两个分离器。后将猫移了一个位置，线路短了很多，一根电话线就能解决了，只接了一个分离器，会不会是这原因呢？于是将线重新拔插了一下，在猫的前面加了一个分离器，问题解决，原来那个数值8变成了15以上。不知此数值要多少以上才算合格。
