Lubuntu connect to wifi
sudo apt-get install network-manager-gnome
By default, NetworkManager does not manage interfaces that appear in /etc/network/interfaces. You can change this behaviour.
backup the current interfaces file:
sudo cp /etc/network/interfaces /etc/network_interfaces_backup Then open the file:
sudo nano /etc/network/interfaces Delete everything in that file and copy and paste the following:
auto lo iface lo inet loopback Save, stop and start network manager:
sudo service network-manager restart reboot
