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: noBut sudo rfkill unblock wifi doesn't change anything.
Any suggestions on how to resolve?

#### wireless info END ############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.
