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?

This can be temporarily fixed by
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.
