I have installed Ubuntu on a new HP Windows 10 laptop, but the wifi is not working. Nothing happens when I click Enable Wifi and Wifi Networks is greyed out. Wifi works ok in Windows.

Wireless info is below.

I note that rfkill shows a soft block,

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

But sudo rfkill unblock wifi doesn't change anything.

Any suggestions on how to resolve?

This can be temporarily fixed by

sudo modprobe -r acer_wmi

To fix it permanently you need to blacklist this module.

But a better solution is to report this issue to Launchpad to get it fixed upstream.

  • Thanks that seems to have resolved it, and adding "blacklist acer_wmi" to /etc/modprobe.d/blacklist.conf. I don't know what Launchpad is. Commented Mar 21, 2016 at 13:12
  • Launchpad is where you report Ubuntu bugs. Run ubuntu-bug linux with not blacklisted module and create a bur report. This way it can be fixed for your laptop model without blacklisting.
