You have been subscribed to a public bug:

After upgrading to 14.10 I can no longer connect to any wifi network
that has WPA authentication regardless of the wifi adapter used (built
in BCM4331 and USB dongle RTL8188C). The same setup was working fine
before the upgrade. I am able to connect to open networks, which I
tested by tethering to a wifi hotspot on my phone. USB tethering also
works. I have confirmed that the wifi password is correct and have even
removed and added the network. THis is on a 2012 Mac Mini.

Expected behaviour: The wifi adapter should have connected to my network

Actual behaviour: The wifi adapter is not able to connect. 'dmesg' is
full of the following error messages:
