Switching wireless adapters loses all rules

[Derek Frye <frye0031 umn edu>]

I recently switched network cards from a prism54 chipset card to a 
rt2500 chipset. Originally, NetworkManager didn't show my network in the 
list (though the network still shows in kismet). So I chose "connect to 
other wireless network", typed in the details (essid and hex key) and it 
connected fine. The network strength is very good.

After every reboot NetworkManager doesn't show the network in the list, 
so I manually add the network and it connects. How can NM "forget" the 
details and I have to add them back? Is there a file somewhere storing 
the Networks I've associated with, or those available? Nothing in 
/etc/NetworkManager except an empty dispatcher.d.
