Ubuntu 无法连接到互联网

因此我无法使用我的 Ubuntu 操作系统进行连接，但我可以用 Windows 上网。我可以用谷歌上网，但只要我尝试其他网站，它就会崩溃

我跑了ifconfig，得到了以下结果

然后我尝试运行一些程序并得到

~$ host google.com
;; connection timed out; no servers could be reached

任何帮助都将不胜感激

答案1

尝试不同的 DNS 设置：8.8.8.8 和 8.8.4.4（此处有简短指南，可能有点过时，但应该可以起作用：http://ubuntuforums.org/showthread.php?t=2078398）

另外，请确保您的子网正确。我日常工作中管理着大量网络，子网输入错误可能会导致各种问题。
