I am using HP envy x360 laptop with Ubuntu 16.04. I can use the wired network with Ubuntu, but for some reason I cannot connect to WiFi. What should I do use WiFi with Ubuntu 16.4 ?

I did rfkill list and it shows me this information:

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

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

2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

I did some research and read some other AskUbuntu answer, but nothing worked. Can somebody help me ?

Run in terminal

sudo tee /etc/modprobe.d/blacklist-acer.conf <<< "blacklist acer_wmi"

and reboot.

  • It worked. Thank you so much for your answer. I have question though: I have tried something like this before and after rebooting the machine for some reason my audio stopped working. What can I do if audio doesn't work ?

  • Does the audio work now?

  • So this solution does not affect audio. If something happens, ask a new question. Do not forget to accept this answer.

The problem is with linux kernel which comes with ubuntu 16.04 lts that is 4.4.0 hwe generic, just upgrade your kernel to 4.8 and it solves the problem.

sudo apt-get install --install-recommends xserver-xorg-hwe-16.04 

or

sudo apt install linux-generic-hwe-16.04

and then reboot

Something went wrong after a 300 MB software update and I'm facing the same problem again.

Tried long and hard before I gave up and bought TP-Link TL-WN725N 150Mbps Wireless N Nano USB Adapter. Worked right out of the box. All wifi networks fully visible.
