I also think, that it is not a problem of network-manager.
I also have this problem, that the connection disassembles again while
trying to establish it (deauthenticating by local choice (reason=3)) But
I only observe this on a specific network. Windows computers and my
Android device can connect to it, only Ubuntu can't. Setting a static IP
address solves this problem and the connection works in my case.
I think, maybe the threshold for getting an IP address from the DHCP
server is set too small. In case you have a slow DHCP server it takes
maybe longer. If one would wait 500 miliseconds longer, you would get an
IP (this is maybe what the other devices do).
This network I speak from was not secured (open network). Uninstalling
network-manager did not solve the problem. I also tried to connect with
the shell tools.
