用的AC2100，手上还有一个R6220，都是128M内存，同时开 网易云解锁 和 小猫咪/怕死我 之类的软件，用不了多久必定会经历 爆内存->小猫咪被kill->dnsmasq一起挂导致全网络因为没有DNS上不了网->直到小猫咪自动重启才会正常
不论是r6220还是ac2100都有这个问题。newifi3这种512M内存的就从没有出现这种问题（当然这玩意flash太小，也是没有软用，刷上花式赛各种插件的固件，就会遇到因为可用flash太小导致运行缓存写满flash，最后结果就是各种奇葩找不到头绪的问题）
所以天天这找固件，翻花样玩各种插件，可能根本就没有什么用。完全不稳定，几小时就会挂一次。不稳定的路由器，没有存在的价值。
AC2100可能只配当个AP
以下是dmesg:
