因此,在我目前的位置(在工作中),我的 Ubuntu 机器无法连接到以太网。我可以看到它,这意味着当我插入电缆时它被列为一个选项,但是计算机始终无法建立连接并最终放弃。我在家里连接到以太网没有问题。我的旧电脑(也是 ubuntu,但版本为 12.04)也没有遇到此以太网的任何问题。目前我正在连接到 wifi。
从其他线程来看,似乎需要以下信息:

有什么建议么?
提前致谢 :)
编辑:我尝试查看的末尾/var/log/kern.log
,并得到以下内容:

在此过程中,顶角的“四分之一圆”图标呈现“波浪”动画,表示它正在工作,并且在某个时候出现一条消息,显示“有线网络//已断开连接”(两行)。这对任何人有帮助吗?
答案1
我应该羞愧地透露一下解决方案:
显然,新硬件必须在我的工作中注册(使用 macaddress),在此之前不允许连接。所以问题解决了,不是由 Ubuntu 引起的。
编辑:是的,Eric,你一下子就搞定了(不过直到后来才看到你的评论)。我已经通过电子邮件联系了 IT 支持人员,但他们处理得有点慢。
