Wireless won't connect again after disconnection

[PureTryOut]

When my laptop somehow loses Wi-Fi connection (out of range, hibernating), it won't connect to the network again.
It asks me like 4 times to insert the password, but it's already filled in, and it's the correct one. After those 4 times it just says disconnected, and the network disappears from the list.
To fix this I have to restart my computer, but when I lose connection again, it just starts all over.

I'm running Xubuntu 12.10

It looks like the restart works at least for awhile. Do you use the disconnect
option before you hibernate?
