After the upgrade of my laptop to 14.04, I have problems to enable the Wi-Fi.

My Wireless card is 

01:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

I had tried the "tricks" from here and here but nothing worked. The proposed solutions applied for 12.04 so I believe that's why I am not able to enable the Wireless.

I tried also the below:

sudo rfkill unblock all
sudo rfkill list

but with no luck..

0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
1: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

I tried also with the Super+F12 and/or Fn+F12 but the message is the same in "Network manager":

Wi-Fi is disabled by hardware switch

From all the above it seems that the hardware is blocked (somehow). From bios I also enabled whatever related with "Wi-Fi/WLAN" but again no luck.

The result of lsmod is:

Does anyone have an idea what else should be done in order to enable my Wireless card?

Is there any backport software from which i can pull the necessary driver or is already included in linux-kernel?

Thanks in advance!

I had the same problem, found a solution on a forum and it worked for me. I am using a Toshiba Satellite L750 with Qualcomm Atheros AR9585 and my wi-fi was hardware blocked. So I did what was said in that forum. I simply rebooted and immediately I pressed my wi-fi activation keyboard combination (FN+F8) and the led for wi-fi turned on and so my wi-fi was hardware unblocked.

I've got the similar problem with ath9k driver.
I solved this problem with a workaround that I found here.

echo "options asus_nb_wmi wapf=4" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf

This command that I've inserted above change the default behavior of ath9k.
After this change I noticed a strange things because network led indicator says that I'm offline, but I can go online through my wireless network card.

I hope this could help you.
