Other questioners with the same issue ( example: https://answers.launchpad.net/ubuntu...uestion/159413 ) seems to indicate that hardware has a Broadcom 4318 chipset.
If so, the the following command will automatically download and install the correct kernel module (driver) for your otherwise incompatible hardware. While connected to the internet, open a terminal window and enter:
After the package manager has installed, you will need to reboot for the new kernel module to load properly. (There are ways to load the module without rebooting, but rebooting is the simplest).
sudo apt-get install firmware-b43-installer
If your hardware works afterward, please use the Thread Tools on this page to make the thread [SOLVED].
If your hardware still does not work afterward, take a look at the help page specifically for that family of Broadcom chipsets: https://help.ubuntu.com/community/Wi...Driver/bcm43xx
