I have a fresh install of Ubuntu 14.04 on an HP Pavilion DM4 1200. I can see all of the local SSID's in my area including my own. However when I provide my WPA Personal key to login into my wireless Apple Router it does not authenticate and times out. I can connect via Ethernet.
I have searched many of the Ubuntu solutions including building and updating the more recent Broadcom STA driver without success. I have updated the installation. I haven't found this specific issue and would appreciate being led in the corrective direction.
