I have a similar problem which is that network manager tends to forget the wireless password sometimes. Here is what happens:
1. I am connected
2. I suddenly loose connection
3. When I try to reconnect network manager does not react to my click on the network name, that is, it does not even try to connect it simply shows no reaction and no cycling green or grey bubbles.
4. When I go to edit connection and click on wireless my wireless ap is unter last used: "Never" even though I was just connected.
5. I have to click edit, enter the system password (or is it for the keyring?!?) and then go to security and reenter the password, i notice that the password field is empty when the dialoge opens.
6. Sometimes I have to repeat steps 3-5 (suspending/resuming helps sometimes if it wasnt successful after several tries through 3-5)
7. I can connect now.
This happens serveral times a week. Analogous to being connected and loosing the connection I sometimes also resume from standby to find that i can not connect, here also steps 3-5 are the same.
While the above steps show a workaround this is quite annoying as everyone can see, especially if you quickly need connectivity.
