Automatic cable <-> wifi switching not working with a WPA PSK-TKIP wlan with hidden SSID

[Achim Bohnet <ach mpe mpg de>]

Hi,
I tried to day knetworkmanager on Kubuntu/Dapper on a Dell D600 laptop
with IPW2200.  First I noticed that after a reboot

  o the <hidden> wlan was not listed in knetnworkmanager menu.
    The manual configuration worked and the wlan is now listed
    in the knetworkmanager menu.

but

  o when I plug the wire ethernet, networkmanager continued to use
    the wlan connection :(  I had to switch the wire connection on
    via the menu to switch from wireless to cable connection.

  o unplugging the wire cable stopped the eth0 but did not active
    the wifi connection.

I don't have a WEP or open AP, so I can't test if automatic switching
works with them.

Is this a known problem?
