Comment 34 for bug 339313

plasma-widget-network-manager from kubuntu-experimental behaves a LOT better. On initially connecting, I entered the WEP key and checked "connect automatically", and it asked for the connection details a second time. Patiently I added them in, and lo and behold, connectivity. It also connects automatically on logging in, which is nice.

So not 100% ideal behaviour, but FAR better than the out-of-the-box setup.
