I have tried obtaining the driver from the official website, but it appears that they've changed the website making it impossible to use it. Luckily, there is a guide on the Ubuntu forum.
Use the results from Google Search to access the page: https://goo.gl/Kle1Bh
Secondly, use the Dropbox link to download the package then follow the instructions to install the driver.
Note: You will need Internet for the time being through cable until you make it work.
