Best Answer
You may be suffering from a clash with the
acer-wmi
kernel module.rfkill list all
says it is "acer-wireless: soft blocked: yes"try the following:
Then add
blacklist acer-wmi
as a new line at the end of the file.Save and reboot.
Rerun
rfkill list all
again - if there still is a "hard-block" you have disabled the wifi via a switch or a Fn key type wireless on/off.On some laptops the hardware switch can be quite small to find - check your laptop manual.
