just a slightly irritating problem:
I have two wifi networks in my home, and both have their WPA keys stored in the keychain. However if I am connected to one, but need to change to the other in mid-session, it asks me for the WPA key. Irritating because keys are quite long and cumbersome.
It doesn't do this at login time: always selects the last network I was using (or tried to use), so the keychain clearly knows the keys.
How can I get this behaviour also when I change networks in mid-session?
