Updating the Killer Wireless in Ubuntu

There are two ways to update the drivers for the Killer Wireless card. The simplest method is to update the Linux Firmware package as a whole, which is outlined in the first section below.

If you only want the specific Killer Wireless driver, you can pull that from the Linux Firmware and install it as well, which has been outlined in the second section below.
