ASUS F550V WiFi Problem in Ubuntu 13 04

This note explains how to resolve a WiFi problem related to Atheross AR9485 wireless card. It seems that when searching ASUS F550V (29th of July, 2013), only few web pages come out, so this article use the title with a keyword "ASUS F550V". Nevertheless, this problem relates, in fact, to the wireless card, Atheros AR9485. You can search Athero AR9485 to probably find a solution. The solution here mainly is from the Lonnie Lee Bests solution found in launchpad.

Symptoms

First, of course, the WiFi does not work, but the wired connection is OK. When you move the mouse pointer to the network icon in the upper-right corner, you may see this: wi-fi disabled by hardware switch. The wireless basically is functionless and looks like a driver problem, because when operating the laptop under Windows 8, the WiFi works normally.

The Solution

If in double, you can use the commands, lspci and grep, to check your wireless adapter. If nothing comes out, try sudo.

lspci | grep -i wireless

The terminal should print out the below information:

03:00.0 Network controller: Atheros Communications Inc. AR9485 Wireless Network Adapter (rev 01)

Here is what you do to sort out the problem. First of all open the blacklist.conf. You would need to use sudo, because this is a system file in /etc folder. Below uses gedit to edit the file.

sudo gedit /etc/modprobe.d/blacklist.conf

Type in the following line at the end of the file and save it.

blacklist asus-nb-wmi

Restart the computer. Then the WiFi should start to work.
