今天XX來機(jī)房弄點(diǎn)腦，要用Linux上網(wǎng)，配置好了IP，但是鏈接不上，始終顯示devic not managed，
上網(wǎng)google了一下，原來是系統(tǒng)網(wǎng)絡(luò)設(shè)置里面的manged設(shè)為了false，改成ture就OK了，具體方法如下。
Step 1 : Go to the Terminal ( Applications->Accessories->Terminal ) and type sudo gedit /etc/NetworkManager/nm-system-settings.conf
Step 2 : A window would now popup displaying the contents of the nm-system-settings.conf file
Step 3 : Now Change "managed=false" to "managed=true"
Step 4 : Save the file and close the window
Step 5 : Now back in the terminal type sudo killall nm-system-settings
Step 6 : Thats it, your network interface should now be detected and it should attempt to connect to a network.
