and after reboot laptop have acer-wireless lan in rfkill list must run command: rmmod -f acer-wmi , echo "blacklist acer.wmi" | sudo tee /etc/modprobe.d/acer-wmi.conf , wait few minutes/hours

iwconfig lo        no wireless extensions.  wlp7s0    ieee 802.11abgn  essid:"......."             mode:managed  frequency:5.24 ghz  access point:......as:32              bit rate=26 mb/s   tx-power=20 dbm              retry short limit:7   rts thr:off   fragment thr:off           encryption key:off           power management:on           link quality=52/70  signal level=-58 dbm             rx invalid nwid:0  rx invalid crypt:0  rx invalid frag:0           tx excessive retries:0  invalid misc:149   missed beacon:0

run in terminal

sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf <<< "blacklist acer_wmi"

this disable acer_wmi module blocks wi-fi.

your previous command wrong. need remove acer-wmi.conf by

sudo rm /etc/modprobe.d/acer-wmi.conf
