I see they have backported the new version to hardy as well. Theoretically it could be a problem with the backported version, but since you've gotten network-manager-kde to connect (although briefly), it's likely an issue with NetworkManager daemon itself, or the drivers for your card.

You can troubleshoot further by:
1. Try gnome's networkmanager applet (if that works , it's an issue with the kde applet)
2. Try connecting manually without NetworkManager (if that works, it's a bug in NetworkManager daemon, if it doesn't work, it's probably a driver issue)

You can connect manually by, for example, killing NetworkManager, configuring your network parameters in /etc/network/interfaces and performing 'sudo ifup wlan0' (substitute wlan0 with the correct device for your interface...you may also need to 'sudo ifdown wlan0' first).

ADDED: It might also be worthwhile to check the logs (on your machine and the AP) if there is anything of interest there (/var/log/syslog and /var/log/daemon.log are good places to start with)

Re: wireless problem !

I confirm that it is some kind of problem between the kde applet and the daemon NetworkManager. First I reinstalled the package network-manager with the command

sudo apt-get --reinstall install network-manager

and the applet came up right away. on the traybar. I still could not connect, not even from the command line unless I first killed the daemon with the command

sudo killall NetworkManager

then I also uninstalled the kde network manager with the command

sudo apt-get --purge remove network-manager-kde

At this point NetworkManager started to work and now it connects fine. Overall what a mess was upgrading to kubuntu intrepid. I hope this had only to do with the fact that I was one of the few that upgraded from a kubuntu hardy remix installation with kde4.1.
