acer phy0 wifi lan hard blocked (and fn+F3 doesn't work)

Asked by André Scarpinati Luchetti on 2018-03-16

WiFi was working well on Ubuntu and Windows in my acer notebook. Pressing fn+F3 would switch Wifi between on and off. But when I updated to Ubuntu 17.10, wifi stopped working only in Ubuntu, and now fn+f3 in Ubuntu switches between "Airplane mode enabled" and "Airplane mode disabled".

This command "rfkill list all" returns:
0: acer-wireless: Wireless LAN
 Soft blocked: no
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: yes

Following the instruction from Wireless Troubleshooting Procedure (https://help.ubuntu.com/community/WirelessTroubleshootingProcedure), I got this output:

If you reset the BIOS to failsafe then reset it up is it OK?

Manfred Hampl (m-hampl) said : #2

"/etc/modprobe.d/blacklist.conf:blacklist acer_wmi"
this seems strange to me, if this is an acer device.

Can you help with this problem?
