Earlier today, on my Kubuntu machine, I needed to replace the Network Manager, which is installed by default, with Wicd. Later I found out that Wicd has issues on its own, so I decided to switch back to the Network Manager after I initially uninstalled it. The whole switching back and forth process was a bit tricky considering I didn’t know how to remove and then install back the Network Manager, so I decided to write myself a reminder post. It’s trivial. Hopefully it will help others as well.
First, install Wicd (it’s important that you install Wicd first, because if you don’t, the next step will effectively disable your internet connection):
sudo apt-get install wicd
and now remove the Network Manager:
sudo apt-get --purge autoremove network-manager
Logout and back in and you should be set. Your Wicd GUI client should be visible in the tray icon area.
First, install the Network Manager:
sudo apt-get install network-manager
You’ll also need to install back the plasma network manager tray icon tool. Otherwise, your network will be enabled, but you won’t have a GUI tool to select from Wi-Fi connections.
sudo apt-get install plasma-nm
Now you can uninstall Wicd:
sudo apt-get --purge autoremove wicd
Okay, you should be set. Log out and back in and your plasma network manager tool should be available in the tray area for you to manage your wireless connections.
