Managing Wi-Fi with kNetworkManager

I use Wi-Fi connection at work. I've also got one at home recently. I was looking for a tool for managing wireless networks. I wanted it to be easy in use and configuration, just like at Windows. I've found kNetworkManager. It seems to meet all of my expectations.

I faced some problems at the beginning - it simply didn't want to manage my networks :) I've solved the problem by removing all the lines describing network devices in
/etc/network/interfaces

You can find description (in polish) of installation procedure
here. It also contains tips how to configure password manager so you are not ask for the network password every time you log in.
