I ran nmcli nm after suspending and got

RUNNING         STATE           WIFI-HARDWARE   WIFI       WWAN-HARDWARE        
running         disconnected    disabled        disabled   enabled 

This output is different than most threads I've seen so that is why I'm making a new post.

lshw -C network shows:

Attempted fix(s)

  1. I tried

    sudo gedit /etc/pm/config.d/config
    

    and put in:

    SUSPEND_MODULES="iwlwifi"
    

    I also tried to put in:

    SUSPEND_MODULES="r8169"
    

    out of desperation.

    Both of these did nothing...

  2. I tried:

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

    and put in:

    #!/bin/sh
    
    case $1 in
    
    suspend|suspend_hybrid|hibernate)
        sudo nmcli n off
        ;;
        resume|thaw)
            sudo nmcli n on
        ;;
    esac
    

    This made my Wi-Fi work, but took away my ability to suspend or hibernate. Closing my lid would simply log me out and turn of my screen, nothing more...

Help would be most certainly appreciated! Thank you!

According to Webupd8 you need to edit /etc/pm/config.d/unload_modules configuration file by adding the following line :

SUSPEND_MODULES="$SUSPEND_MODULES <kernel_module_used_by_the_interface>"

In your case the kernel module in use is iwlwifi :

SUSPEND_MODULES="$SUSPEND_MODULES iwlwifi"

then edit your 10_resume_wifi like the following example:

#!/bin/sh

case "${1}" in
  resume|thaw)
    nmcli r wifi off && nmcli r wifi on;
esac
