Hi, this is a long lasting problem that I didn’t really manage to fix when I started using linux (Mint, Cinnamon). But now that I’ve been using it regularly for half a year and I have more experience in fiddling around, I’m trying to get it resolved.

Whenever I suspend the laptop (or close the lid, which does it automatically) the Wifi and sometimes an external monitor don’t work anymore, I don’t know what the problem is. The wifi is fixed by powering on and off again. To fix the monitor sometimes even powering off and on again didn’t fix it, I usually waited for the next day and it worked again.

I’ve no idea of how to fix this (Linux Mint forums didn’t help at the time)

Laptop is an MSI GS65-Stealth-Thin-8RF running Linux Mint, with Cinnamon Desktop

    You need to unload your wifi module before suspend.

    Without systemd it’s easy:

    create a file /etc/pm/config.d/config containing:

    HOOK_BLACKLIST="wireless"
SUSPEND_MODULES=”NAME_OF_YOUR_WIFI_MODULE”
SUSPEND_MODULES=”wl”

    With systemd try this

    create a file /usr/lib/systemd/system-sleep/fix-wifi.sh containing (fuck this editor, replace the “##” with “&&”) :

    #!/bin/bash
[ "$1" = "post" ] ## exec /usr/sbin/modprobe NAME_OF_YOUR_WIFI_MODULE
[ "$1" = "pre" ] ## exec /usr/sbin/modprobe -r NAME_OF_YOUR_WIFI_MODULE
exit 0

    and make it executable with chmod 755 /usr/lib/systemd/system-sleep/fix-wifi.sh

      It doesn’t work, should it look like this the script?

      #!/bin/sh
[ "$1" = "post" ] ## exec /usr/sbin/modprobe Intel Corporation Wireless-AC 9260
[ "$1" = "pre" ] ## exec /usr/sbin/modprobe -r Intel Corporation Wireless-AC 9260
exit 0

      EDIT: should the name be something like wlp62s0 ??? I’m going to try it

            well, are you sure the script is executed? I don’t know systemd enough :-(

            First, do a test in command line modprobe -r iwlwifi

            then suspend your laptop, resume it after a few seconds then do

            modprobe iwlwifi

            and see if wifi is working

              Yeah, thanks for the help even if you don’t know much. I get stuck on the first command where I get this error:

              rmmod: ERROR: ../libkmod/libkmod-module.c:799 kmod_module_remove_module() could not remove 'iwlmvm': Operation not permitted
rmmod: ERROR: could not remove module iwlmvm: Operation not permitted
