Probably, this is the list. Fedora might have changed things, and if you 
feel the need to report a bug, you should do so through  Fedora's

I had a similar problem in opensuse 10.2. I visited daughter in Faraway 
City. She lives in a block of (very nice) flats, and of course a lot of 
people there have wireless. Daughter included.

I found I didn't have any problem associating with her AP, and I could 
choose it from a list, and there were flashing messages as other APs 
came and went, but it was very prone to forgetting the (WPA) password. 
Not always, but certainly often.

Subsequent discussion here and on -test suggest strongly that, while 
network manager works for a lot of people, it doesn't work at all for 
anything but the most common case.

Take a look at

Me, I'm ignoring network manager for a while longer, and configuring my 
wireless in other ways. As I've been doing since FC3.
