This question already has an answer here:

I've messed around with my network settings lately and I have no idea what I've done, but now my wifi doesn't seem to be working right. When I boot my system up I get the message

booting system without full network configuration

I tried following the guide here to reset my /etc/network/interfaces file, and now I get the same message at boot but my network manager doesn't even turn on when I login.

Any advice would be appreciated.

If this is the case you can try with some changes,

sudo nano /etc/network/interfaces

After this press CtrlX and N to remove the changes. After doing this it is must to restarts the system.

sudo reboot

Hope this helps.
