I followed this guide: Installing Broadcom Wireless Drivers
When I went to "Additional Drivers", and under the "Broadcom Corporation : BCM43142 802.11b/g/n" it says "This device is using an alternative driver. But before it said, this device is not working or something like that.
This was a fresh install and the only things I did were all in the guide of "Installing Broadcom Wireless Devices."
But later, I found out that this device isn't working at all from this bug, https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/923809.
Plus I get the result after installing "bcmwl-kernel-source",
Error! Bad return status for module build on kernel: 3.16.0-38-generic (x86_64)
