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?

Tried rfkill unblock acer-wirelessgave output Bogus unblock argument 'acer-wireless'.

Here's iwconfig

The rfkill list:



0: phy0: Wireless LAN

    Soft blocked: no

    Hard blocked: no

1: acer-wireless: Wireless LAN

    Soft blocked: yes

    Hard blocked: no


So I ran sudo rfkill unblock all and nothing happened:



connor@connor:~$ sudo rfkill unblock all

connor@connor:~$ rfkill list

0: phy0: Wireless LAN

    Soft blocked: no

    Hard blocked: no

1: acer-wireless: Wireless LAN

    Soft blocked: yes

    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?

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 AR9287 Wireless Network


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.
