I'm using an I'm using an HP Pavillion x360 which I'm using to dual boot Windows 10 and Ubuntu 16.04.1. I am unable to connect to wifi and get the message "Wi-Fi networks - device not ready".

Regarding the wireless card:

$ lspci -v

And the firmware:

EDIT:

I changed the regulatory domain to be in the US. I then updated the firmware:

cd /lib/firmware
sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-21.ucode

After which it still seemed to be the same version

  • Especially note the firmware update in the duplicate. – chili555 Jul 31 '16 at 21:02
  • @chili555 i set the regulatory domain, updated the firmware, rebooted and still cannot connect ("Wi-Fi Networks device not ready") – jesseWUT Jul 31 '16 at 21:16
  • And how about the changes in the router? Any changes here? dmesg | grep iwl? – chili555 Jul 31 '16 at 21:24
  • @chili555 It is in WPA2-AES. I didn't play around with any of the other settings but this machine connects fine using windows so I don't imagine that would be the problem. Also dmesg | grep iwl shows no change – jesseWUT Jul 31 '16 at 21:51
  • Including the firmware? – chili555 Jul 31 '16 at 22:09
  • @chili555 yes, exactly the same – jesseWUT Jul 31 '16 at 22:13
  • It loads the -16 firmware still? What is the result of: rfkill list all? And also: uname -r – chili555 Jul 31 '16 at 22:36
  • @chili555 outputs are in the recent edit – jesseWUT Aug 01 '16 at 02:01
  • Let's try -17 instead: cd /lib/firmware and then: sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-17.ucode Reboot. Any improvement? – chili555 Aug 01 '16 at 12:27
  • @chili555 Looks like this time the firmware update took, [ 2.318070] iwlwifi 0000:02:00.0: loaded firmware version 17.265642.0 op_mode iwlmvm but I still get device not ready. rfkill list all and uname -r show the same output – jesseWUT Aug 01 '16 at 23:06
  • I have reopened the question. Please provide the diagnostics as outlined here: http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos/425180#425180 Paste the result here: http://paste.ubuntu.com Give us the link in your response. – chili555 Aug 02 '16 at 00:36

Please note in your paste:

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

And also:

hp_wmi                 16384  0
acer_wmi               20480  0

Your computer is not both an Acer and an HP! Let's unload and blacklist the acer-wmi module.

sudo -i
modprobe -r acer-wmi
echo "blacklist acer-wmi"  >>  /etc/modprobe.d/blacklist.conf
exit

Your wireless should now be working, but it might take a reboot.

  • Following this and a reboot the "Enable Wireless" option has disappeared when I click on Network Manager. Also: $ rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no – jesseWUT Aug 02 '16 at 02:22
  • Did the driver module load? lsmod | grep iwl If not load it: sudo modprobe iwlwifi Any errors or clues here? dmesg | grep iwl As before: http://paste.ubuntu.com and give us the link. – chili555 Aug 02 '16 at 13:33
  • not sure what happened but I turned my machine back on to try this and the wifi worked! Thanks so much for all your help – jesseWUT Aug 02 '16 at 23:00
  • Awesome! Glad it's working. – chili555 Aug 03 '16 at 00:03

chili555's answer worked for me as well! Too new to comment, but I think it is important to let folks know this answer worked for more than one person on the same machine with the same hardware. I also tried the following which worked...

sudo -s
pico /etc/modprobe.d/blacklist-ua-acer-wmi.conf
(Add the following content)
blacklist acer-wmi (save and close file)
init 6 (to restart)
