I searched many solutions on this site but most of them were referring to Broadcom Wifi drivers while mine has Intel one.

Pay you attention command lspci -knn | grep Net -A2 output contains no line Kernel driver in use. Just do

sudo modprobe ath9k

Next check the wireless module for soft and hard block

sudo rfkill list

As your laptop is Acer, try

echo blacklist acer-wmi | sudo tee -a /etc/modprobe.d/blacklist-acer-wmi.conf

Reboot the laptop and try lspci -knn | grep Net -A2 and sudo rfkill list again.

If nothing helps try No Wifi on Acer Aspire E5 573 on any Linux Platform.

And finally try solution from post #22 from here.
