因此,我的互联网间歇性地消失了。我不知道为什么!
有一阵子我以为是当我允许Update Manager自动检查更新时发生的,但我不认为现在是这种情况。
就是这样,我不知道如何检查计算机的活动日志以尝试辨别为什么会发生这种情况,或者一旦这样做就该寻找什么(或者如何在此处重新发布它,所以有人比我想像的要聪明得多)。 如何正确解决此问题?
编辑:我已经在这里加粗了我想强调的内容。我很欣赏建议的修复程序,但是我注意到计算机的行为发生了明显变化-自从我关闭了旋转台式机功能以来,我没有遇到任何连接问题。由于这是随机情况,因此我不想在外观设置和保持与wifi的连接能力之间建立关联。那么我该如何调查?
EDIT2:好的,所以,这在Ubuntu 13.04上仍然是一个明显的问题,因此我删除了12.04标记,因为它似乎不适用。它似乎已经消失了一段时间,但又回来了,也许是由于升级的结果(但是我必须这样做,Unity的速度要快得多!Eee)到目前为止,我已经能够通过转到系统设置>网络来重新连接>选择我的网络,然后向右橙色箭头>设置>将MTU设置从“自动”切换为“ 1”,然后再回到“自动”并保存。如果问题确实出在此设置上,则另一篇文章中描述的方法并不表示如何找到正确的MTU设置。我有办法确定最佳的MTU吗?顺便说一句,这对于我的家庭网络上的Windows或OSX机器不是问题,只是这个家伙:(
EDIT3:根据以下请求,以下是输出dmesg | tail

我用Google搜索了最后一行nss-myhostname
,关于其他各种Linux发行版都获得了很多好评,而关于Ubuntu却一无所获:/真的相关吗?
