I have this problem too. I also had the problem of the WiFi not working in Unity, I would enter the WiFi password and nothing happened. After I installed Gnome desktop, which I use, I was able to enter the WiFi password by clicking on the WiFi icon, opening Wi-Fi Settings, next to my hub was a configure icon, I set the password in there under the Security tab. Now I can connect without problems in both Unity and Gnome desktops. Mine was a fresh install Compaq CQ58 laptop. I still can't choose a WiFi at the login screen, but once logged in I'm okay now.

WiFi works after loggin it, but it should be working before also, if not, what's the point in having an icon there :) I get the following message: Failed to add/activate connection. - (1) Insufficient privileges. - see image. This worked fine in 14.04. I have noticed this problem in both my desktop (Broadcom WiFi) and Laptop (Intel WiFi) - So it has nothing to be with the chip. Feel free to ask for more info.
