First solution is to type in terminal:

sudo -i /bin/systemctl enable wifi-resume.service exit

If this will not work, then below you have solution.

Second solution is to create a file:

sudo nano /etc/pm/sleep.d/10_resume_wifi

Paste below this:

#!/bin/bash
case "${1}" in
   resume|thaw) 
    nmcli radio wifi off && nmcli radio wifi on;; 
esac 

Ctrl+o to save, Ctrl+x to exit.

Then type in terminal:

sudo chmod +x /etc/pm/sleep.d/10_resume_wifi 

to make the file executable

If this will not work put this into the file mentioned above:

#!/bin/bash 
case $1 in
    resume|thaw)
        nmcli radio wifi off && nmcli radio wifi on;; 
esac

If it will not work, put this:

#!/bin/bash 
case $1 in
    post|resume|thaw) 
        nmcli radio wifi off && nmcli radio wifi on;; 
esac
