Public bug reported:
After the last NetworkManager update in Precise, wifi connection resets
after setting the password, so there is like 10 seconds of connection,
and afterwards it resets and a dialog asks to enter the password again.
Disabling IPv6 for this connection solved the problem.
Here are some relevant lines from the system log when the wifi
connection reset happens:
