還是手賤，在修改了網(wǎng)絡(luò)配置和更新后，開機(jī)，機(jī)子木有無線網(wǎng)卡了，有線網(wǎng)卡也非常詭異，必須要restart network才能連出去。
在打開系統(tǒng)的網(wǎng)絡(luò)連接面板時，出現(xiàn)系統(tǒng)的網(wǎng)絡(luò)服務(wù)與此版本的網(wǎng)絡(luò)管理器不兼容的錯誤。
利用萬能的Google，找到了解決辦法。方法比較匪夷所思，我反正木有理解，但是就這么成了。。。
方法就是4步走，看下面的引用：
First open Terminal and log in as root.
# su
After that go the correct folder.
# cd /etc/NetworkManager/system-connections/
Now take a look at the content of this folder. If you had a VPN connection e.g. there must be a file with the name of that connection.
# ls -la
Now you can remove that file or you can move it to another folder (so you can set it back if this solution does not work for your problem).
To move the file to your personal folder use the following command:
# mv filename> /home/username>/ #username是你的用戶名
Now the only thing left is starting the Network Manager:
# NetworkManager
當(dāng)～～～你的網(wǎng)絡(luò)管理界面里出現(xiàn)了久違的無線網(wǎng)卡～LOL
PS：可能會出現(xiàn)未配置的情況，請reboot一下
