This question already has an answer here:

I just did a clean install, overwriting my old Windows. I'm pretty much a novice and don't know where to start. I've tried reading a few answers that seemed relevant but find it all a bit confusing, the people asking seem to have a better grasp on using terminal code etc than I do and I don't want to take any risks.

Currently, I'm doing a full update using an ethernet cable - hoping that might fix it but suspect from the questions I've seen on my adapter it probably won't.

My wireless adapter is a Qualcomm Atheros AR9485 Wireless Network Adapter.

When I go into the network setting and try to turn on the wireless it turns on for half a second then turns off.

Bearing in mind I am a complete novice, is anyone able to assist in getting the wireless working?

The rfkill list:

    Hard blocked: no
1: acer-wireless: Wireless LAN
    Soft blocked: yes

So I ran sudo rfkill unblock all and nothing happened:

connor@connor:~$ sudo rfkill unblock all
connor@connor:~$ rfkill list

    Hard blocked: no

UPD: Using this troubleshooting guide I ran sudo lshw

Here is the output:

I can't make heads or tails of it. Anyone else? Is driver=pcieport even a driver?

A million rep points from me for Danatela - how can I reward this wonderful human being for all his/her help?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
OK, thank you for taking the time @Danatela - I understand you are a volunteer and I appreciate what you do –  ConnorJ Mar 31 at 10:23
    
@ChrisR. asks: A soft block is usually the wireless being switched off on by the keyboard. Is there a function key that turns the wireless on off (usually looks like a radio tower with radio waves coming from it)? –  Danatela Apr 7 at 15:46
    
Well, I did soft block my wireless once, this is the link for how I solved it: askubuntu.com/questions/62730/… –  mmm3743 Apr 10 at 9:06
    
Keyboard button doesn't work –  ConnorJ Apr 11 at 10:47
    
@mmm3743 How do I "save"? I pasted the code line by line as per the first reply but the commands at the end had no option for saving? –  ConnorJ Apr 11 at 10:51

Try rfkill list

$ rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no

If it shows some devices are soft-blocked, run rfkill unblock ID where ID is number of device. For you solution is to run:

sudo rfkill unblock all

Also try to switch aerial on/off using keyboard. On my notebook it sometimes helps. I use Fn+F11 chord. And the icon looks like threetheethed fork or like the radio – as ChrisR. says.

If it shows that device is hard-blocked, you should unplug your notebook, remove the battery, then press and hold the power button for a while, then try it.

THE SOLUTION

with credits to mmm3743 and fossfreedom

from Cannot change soft block setting to "no" for wireless

Copy and paste (line by line) the following into a terminal:

sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf

Then add blacklist acer-wmi as a new line at the end of the file.

Save and reboot.

Updated original - it said "bogus" unblock argument for ID. Also, the device is inside my laptop so won't be able to do a hard reset like you describe –  ConnorJ Mar 28 at 7:18
    
No hard block on the rfkill list, there is a soft block though - see original post –  ConnorJ Mar 28 at 7:21
    
Would you believe the laptop has an inbuilt battery that I can't remove, lol? I tried the unblock acer-wireless, it still says bogus argument –  ConnorJ Mar 28 at 7:31
    
No output - still can't enable wireless –  ConnorJ Mar 28 at 7:56
    
No output doesn't mean rfkill failed it means something else is broken. –  hbdgaf Mar 28 at 7:58

Is the module asus_nb_wmi loaded? Check:

#lsmod | grep asus

If so, please try a driver parameter:

#sudo -i
#echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
#exit

Reboot and see if the Fn+F2 behavior is changed. If not, try the sequence above again, but with the integer 1 or then 4.

Nope. I tried "1" because that's the output from the lsmod | grep asus command. WHICH IT DOES NOW!!! W00000! –  ConnorJ Apr 11 at 12:12

I am not sure that my answer will definitely work but you can give it a try. Actually the wireless problem has become a common problem in Ubuntu 12.04 and it happened with me too when I installed Ubuntu 12.04. Here is what I did to make it working:

  1. First connect with any wired Internet connection or USB Dongle; It will be needed to download the drivers and it is only one time work.
  2. Open terminal and execute this command:

    sudo jockey-gtk
    

    this application will search for all available drivers and try to download and install if missing.

  3. Once successfully finished, you'll get that some wireless drives has been installed. Just restart your system once.

Hope it works for you too. Reply what happens!
