网络连接出现问题

[leetom]

今天开机不能上网，可能是因为上次试了一下sudo pppoeconf，但是我设置的不自动连接。
开机之后ifconfig只有一个lo。右上角的网络管理器显示未找到有效的活动连接！
interfaces如图，我改成了（中间那些应该是pppoe加进去的吧）

代码： 全选

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

然后可以上网了，但是右上角的网络管理器还是不正常，还是显示未找到有效的活动连接！网络已断开。

网络工具里显示如图2
大家帮忙看看怎么解决~~谢谢了

现在网线换插口后不会自动重连了必须sudo /etc/init.d/networking restart才能重新上网，在网络管理器上重新启用都不行。
