Describe the bug

安卓无线设备休眠一段时间后,查看ipv6状态,地址信息仍在,但是无法连通ipv6网络。
表面的现象为,设备休眠一段时间后,淘宝之类支持ipv6的应用加载页面缓慢或无法加载页面。此时,ping 网关 local link ipv6地址是通的,但ping 公网ipv6 不通。这时关闭wifi后重开,立即能连回ipv6网络。
大概尝试了修改路由器wifi,mtu,广播设置,RA设置,都只能稍微改善这个问题,使得ipv6中断不那么频繁,并不能根治这问题。

备注:
网络拓扑方面,路由器作为ap使用,上联接线连在lan口,其他有线设备也连在lan口,本机ipv6 RA关闭,使用同一子网的光猫处理ipv6 RA 。
IOS的设备刚开始也遇到这样的问题,但把路由器 dl ofdma 和 dl mu-mimo两项关闭后,再也没遇到过ipv6中断。
之前用的路由器,使用自编译的 https://github.com/hanwckf/rt-n56u 固件,一样的网络拓扑,从来没遇到过类似问题。

同样的问题,无线加密换成 WPA2/WPA3 后就没再出现了

@jionkitten
还真是这样,谢谢。可否告知你遇到问题的终端设备是什么牌子的?

我的n个小米的手机:自带无线模块是wifi6的设备,通过wpa2登录,一段时间ipv6会断。自带无线模块是wifi5的设备,通过wpa2登录就没问题。无奈我有台无线模块是wifi6的设备,仍然留在android 10,可能小米编译的时候没加wpa3参数,即使路由器切到wpa2/wpa3,它依然wpa2登录,ipv6会断。

我随便看了下wpa3/2的文档,也没看出是什么特性造成这样的区别。

发现原来自己用的android 10底层的miui后面还有几个新版本,升级了下,新版能用wpa3,问题解决了。

这个没有,我是重度6的用户,很敏感
就是今天最新版容易内存飙升导致挂机
快一年没刷了,哭哭

@hcym 看这周反复改hnat的代码里有kernel panic,memory leak这样的字眼,编译的时候一般会选的更早的代码稳定期
