Use WICD instead of NetworkManager in Ubuntu 12.04

In Kubuntu 12.04, I have noticed that NetworkManager doesn't like to work after a resume from sleep. So I will show you how to replace it with WICD, which is a whole lot more reliable.

Prerequisites

• Any flavor of Ubuntu, version 12.04
• An already-working internet connection with NetworkManager
• NetworkManager not successfully connecting after resume from sleep

How to make the switch

First, install WICD. Open a terminal and type:

sudo apt-get install wicd

Note that this installs wicd-gtk. This is okay for Kubuntu users, as the GTK client is a lot easier to use than the KDE one.

Second, uninstall NetworkManager.

sudo apt-get --purge autoremove network-manager

That's it! Enjoy WICD.
