I've recently installed Ubuntu 14.04 LTS in my ASUS D550CA, and so far things have gone great.

The only problem I've got is the Wi-Fi. It doesn't work.

I've got an Qualcomm Atheros AR9485. I've tried installing the drivers, but the sytem says it doesn't find any.

So I started looking around this forum for solutions.

I've read every single post from this forum about my Wi-Fi network adapter, and I've found nothing that solves my problem.

Let me give you some info about my configuration.

Disclaimer: my configuration is in spanish, so if you don't understand something you can either use Google translate, or use your imagination. :D

When I run $ sudo lshw -C network this is what I get:

At the beginning, you'll see that it says "*-network DEACTIVATED" (or at least that's what I translated), is that something bad?

Then, when I run ipconfig this is what I get:

When I put iwconfig:

eth0      no wireless extensions.



lo        no wireless extensions.

Finally, when I put sudo rfkill list all, I got:

I hope anyone can help me solve this, I've searched a lot and found no solution.

Thanks a lot.
