你两个密码一样，那你是怎么确定你输入的是 ROOT 的密码，而不是当前用户的密码的？

@billlee
手机没有 ROOT 装不了 tcpdump

没有找到原因，重置了一下路由器好了
猜测还是 NAT 的问题

@des 是 TCP_NODELAY set 之后那一步卡住

@vazo 重启之后确实测试能正常一会儿，但过一段时间又出问题了

@cwbsw 我也怀疑是 NAT 的问题，但是电脑正常就有点奇怪

换了一个小米 3 的路由器，也是 Padavan 固件，就没问题

@des 不是吧，直接用 IP 地址也有问题啊
而且 ping 的时候正常，解析 IP 很快

@beijiaoff 都正常的，感觉是路由器配置的问题
有没有什么参数手机和电脑设置差别很大的？

@also24 MTK 的扩展性和耗电都还好吧
感觉 wearOS 的手表耗电都挺高的

@abersheeran 我的小米 max 屏幕碎了的，怎么只给我 15 ？

中文打字 100+/min
英文打字 350+ WPM
能做到这个速度的话，可以不用改
不然的话，就不要说 “打字也很快”
