When I open the connection setting then I press

"wifi key" , airplane mode switches on and off. When I switch the wifi toggle on wireless network, it turns off again, I mean I am not able to turn on the wifi.

I had the same problem with a Toshiba Satellite several times, and solved it doing either:

  1. If you have a dual boot with Windows, and you disable your wifi in Windows, in my case it also blocked the wifi for Ubuntu.

  2. Sometimes the laptop just "hangs" on the hard-blocking and the only way is to remove your laptop battery, which resets the BIOS (my laptop does not have a cmos battery).

First go into BIOS and reset it to defaults. If that does not help, then run in terminal

sudo tee /etc/modprobe.d/blacklist-hp.conf <<< "blacklist hp_wmi"

and reboot.

  • You my savior, thx very much, problem solved.... thank you thank you, god bless you – Ben Hebat Nov 3 '16 at 16:04
  • How did you solve it? By bios reset or blacklisting hp_wmi? – Pilot6 Nov 3 '16 at 16:05
  • Before see your post, I get some advice from google tell me to reset bios, I I have done it, nothing change. Then I try your suggestion (blacklisting hp_wmi, and work well... But when I press the wifi button/key bluetooth is turned on/off too, so however now I can connect to wifi – Ben Hebat Nov 3 '16 at 16:10
  • Please add your laptop model to your question to let people know where it is applicable. – Pilot6 Nov 3 '16 at 16:11
