Hi guys I've just installed Ubuntu 16.04 and I'm connected with an ethernet cable since I can't connect to the Wi-Fi. I know this might sound like a question that was asked a thousand times but I've tried everything I found online and I can't get it to work.

Among the things I did were:

Reinstalling bcmwl-kernel-source; Disabling the Secure Boot; Commenting out some blacklist line(I think it was a line with b43 in it); Also I restarted my laptop infinite times.

I have an SSD with Windows 10 and a HDD partioned in two parts, one of which has Ubuntu. I don't know if this matters.

Any help, please? Thank you, Lorenzo

EDIT: After executing the command 

lspci -knn | grep Net -A2

I get:

03:00.0 Network controller [0280]: Qualcomm Atheros AR9462 Wireless Network Adapter [168c:0034] (rev 01)
    Subsystem: AzureWave AR9462 Wireless Network Adapter [1a3b:2234]
    Kernel driver in use: ath9k
    Kernel modules: ath9k, wl

Also the strangest thing just happened. I opened up my laptop and the Wi-Fi was suddenly working, detecting all the networks. Unfortunately right before I clicked on mine to connect, the Wi-Fi was disconnected and they all disappeared.

One more detail:

rfkill list

Gives as output

1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: asus-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
3: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
5: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

Just ran sudo rfkill list again and I noticed that the Wireless has changed:

1: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: asus-bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
3: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

  • Installing Broadcom drivers was wrong. You do not have a Broadcom adapter. – Pilot6 Oct 04 '16 at 22:02
  • The issue is with rfkill. You never mentioned that you had an Asus laptop. Probably you need to add a wapf=4 parameter to asus_nb_wmi. – Pilot6 Oct 04 '16 at 22:03
  • Why does it matter which computer I have? I didn't think it was important. – BourbonCreams Oct 05 '16 at 11:10

Run in terminal

sudo apt-get purge bcmwl-kernel-source
sudo tee /etc/modprobe.d/asus.conf <<< "options asus_nb_wmi wapf=4"

and reboot.

  • This solved my problem, thanks! Can you explain what it does exactly though? Thank you again. – BourbonCreams Oct 05 '16 at 11:21
  • This commands created /etc/modprobe.d/asus.conf file with options asus_nb_wmi wapf=4 in it. That sets parameters for Asus platform driver to correctly use rfkill. – Pilot6 Oct 05 '16 at 11:26
