I have a Gateway MX6436 with a Broadcom BCM94318MPG WiFi. Everything else works fine but Ubuntu doesn't recognize my WiFi. It says it doesn't have the firmware.

What to do? Please help.

Install firmware-b43-installer from the Ubuntu Software Center.

Ubuntu already includes drivers for Broadcom hardware, but for certain reasons can't include firmware. This has to be done by the user, as shown above.
