Hi All,

I am a newbie on linux. Recently, i decide to try out linux and had opt for ubuntu 16.04.3 LTS. Here is my laptop specs :

https://www.asus.com/us/Laptops/X55...

I would like to use a wireless a/c usb adapter to replace the build-in wireless n adapter. I had downloaded the linux driver here :

http://www.szedup.com/support/drive...

Here is where i met the problem. Unlike windows, i could just click on the installation icon to get the adapter installed. All i get is this file with the name "rtl8821AU_linux_v4.3.14_13455.20150212_BTCOEX20150128-51.tar.gz"...

How do i go about getting it installed?

Thanks in advance...

Windows & Linux are 2 completely different animals & Ubuntu was a poor choice for a linux newbie. You'll probably have to connect the laptop to your router via ethernet cable, then download the driver from the Ubuntu repository. See the following:

I have successfully installed the driver after disabling "secure boot" in bios. However, when i try to enable "secure boot" (after driver installation), the wireless adapter stop working. Is there a way to enable "secure boot" and at the same time let the wireless adapter work?

Note: if you're installing a wireless driver, you will need some other kind of internet connection to do this—wired connection, USB tethering, etc.


Under System Settings, double-click Additional Drivers


In Ubuntu 12.10 (Quantal Quetzal), Additional Drivers has been integrated into software-properties. So search for software sources, and then click on the Additional Drivers tab.


You'll then see that proprietary drivers are not in use. Click Activate to activate the driver and then, when prompted, enter your password and click Authenticate.


Wait for the drivers to download and install.


Then, click Close once the changes have been applied.
