[求]网络问题: 长时间连接网络后 http/ftp传输变得异常缓慢[/助]

lolilolicon

我刚刚重启回来, 网络才恢复正常

重装后已经遇到两次了, 就是系统一直连着无线, 跑久了之后页面载入的速度非常非常龟, 包括pacman下载包也是如此, 但是网络信号是很好的, 并且ping的反应很快

wiki里面读到"The TCP Window Scaling Issue"这段, 有点类似, 但又不像, 因为那种情况下应该是没有任何时候是顺畅的才是吧？

我的网络是通过tp-link路由器连的, 网络管理器是wicd, 开启断线重连, log里有这样的信息:

看起来只是断线重连而已?

什么情况?
