This question already has an answer here:

I have an HP Envy 300 (desktop) running Ubuntu 14.04.

I have both a mini PCI wifi/bluetooth card (Broadcom BCM43228) and USB wifi.

I can see both wireless options in the Networks component of System.

The USB wifi connects both to the unsecured network across the street as well as my secured (WPA/WPA2) network.

The PCI wifi will not authenticate. It sees all the wireless networks available, I can ask it to connect to the unsecured connection across the street and it just doesn't connect. If I ask it to connect to my secured connection, I type in the password and get an authentication error.

I updated the BCM driver yesterday (after which, the PCI wifi does now show up in Networks).

Any other suggestions? FWIW, I had the same behavior when I was attempting to use the PCI wifi when running Windows when the system came out of the box (the PCI card was "factory installed").

Try sudo apt-get install bcmwl-kernel-source if uname -a shows a 3.13 kernel, if it shows a 3.16 kernel then download from http://packages.ubuntu.com/utopic/bcmwl-kernel-source as the ubuntu forums broadcom sticky shows that bcmwl-kernel-source as the correct driver for your chipset

  • Followed the directions in the sticky, installed the noted driver above and same behavior. It will not authenticate on the open wifi network - it says 'Connecting' and then just comes back as Not Connected – kjoakey Mar 2 '15 at 17:49
  • I'd like to be able to use this PCI card to use WoWLAN (which doesn't work on my USB Wifi). – kjoakey Mar 2 '15 at 17:49
  • I would try using the utopic version to see if any improvements were made to the driver – Jeremy31 Mar 2 '15 at 18:15
