for easy network management under gnome

apt-get update;
apt-get install network-manager-gnome; # install the network manager tool
# optional:
apt-get install gnome-nettool; # install network debugging tool


nice tool to manage your weird wired and wireless networks

if it says “device not managed” this means you have some manual settings defined in:

vim /etc/network/interfaces

if you # comment out those and restart your system – the network device should be managable by network-manager-gnome.

# The primary network interface
# allow-hotplug eth0
# iface eth0 inet dhcp


nice tool for debugging network problems
