Machine is a Lenovo T400 with Ubuntu 12.04.1 LTS.
Wireless card installed is an Intel PRO/Wireless 5100 AGN mini-PCIe adapter. I can manage the wireless card manually via iwconfig, but the graphical network configuration control panel and associated menu bar icon don't see the card - it shows the card as unmanaged. In the menu bar icon, under Wireless Network, it says "device not managed".
iwconfig shows the card as managed. lshw provides this info (extra line breaks added for clarity):

(At the moment, I'm just on the unsecured wifi at a Marriott hotel.)
I've done a bit of searching and haven't seen anything on what might fix this. Any help is appreciated. Thanks!
