我有 Ubuntu 14.10。当我工作时,我可以毫无问题地浏览互联网。现在我在家,可以连接,但无法浏览网页。
一些信息:
ifconfig 的输出:

我正在使用网络管理器,这是 nm-tool 的输出:
marcosh@marcoshstudio:~$ nm-tool

我担心文件 /etc/resolv.conf 中的设置会产生干扰:
marcosh@marcoshstudio:~$ cat /etc/resolv.conf
domain mva.local
search mva.local
nameserver 192.168.242.1
那可能吗?
我知道(因为我另一次这样做了),如果我删除并重新安装网络管理器,我将能够从家里浏览,但不能从办公室浏览。我怎样才能避免这种情况并一次性解决我的问题?
