我在 Linux chrubuntu 3.13.0-29-generic 上使用以太网时遇到了一些问题。
网络管理器显示网络已连接,设备已识别,但没有互联网。有趣的是,它有时会打开 google.com,我可以输入查询,但它们非常慢,其他功能都不起作用。以下是一些信息:

我尝试更新驱动程序(从 ASIX 网站下载最新版本),但似乎已将其更新为旧版本(2005 年 8 月 22 日),并且没有帮助。
当我 Ping 8.8.8.8 时,所有数据包都丢失了。
完全相同的网线可以在另一台运行标准 Ubuntu 14.04 的计算机(台式机)上使用。当我使用 Chrome 操作系统时,它也可以在同一台 chromebook 上使用。
有什么想法吗?

问题似乎出在你的 ISP 身上。数据包离开你的计算机/网络后在中途被丢弃。打电话给你的提供商,让他们修复他们的问题
