I have this same issue but have a fix so you don't need to restart. FYI
I'm running mint.
You need to ensure you have the msi-laptop modprobe running. You can
validate that by looking here:
/sys/devices/platform/msi-laptop-pf
If that folder exists msi-laptop is loaded. If not you need to run:
sudo modprobe msi-laptop
Within that folder you can find msi-laptop-pf/wlan. This can control the
wifi and is toggled when your come out of suspend mode.
This is the behaviour for me:
If value is 1 on suspend then wifi stays off
If value is 0 on suspend then value changes to 1 and wifi turns on
The wifi turns on if it's 0 because it is reacting to the change. My workaround
is to toggle this change each time I come out of suspend with this script which
I put in here:
/usr/lib/systemd/system-sleep/msi-wlan-fix.sh
The script:
#!/bin/bash
WLAN_PATH="/sys/devices/platform/msi-laptop-pf/wlan"
case $1/$2 in
pre/*)
# Before suspend: optional
;;
post/*)
# After resume: toggle wlan to trigger hardware
if [ -f "$WLAN_PATH" ]; then
val=$(cat $WLAN_PATH)
# toggle 0->1 or 1->0 to trigger edge
if [ "$val" -eq 1 ]; then
echo 0 > $WLAN_PATH
sleep 0.1
echo 1 > $WLAN_PATH
fi
fi
;;
esac
Note that I still cannot use the airplane mode button but I can just
bind a hotkey to toggle the wifi / bluetooth to the file in the script
if I really want that functionality.
There are other msi modprobes I could test to see if they fix this issue
but for now this fixes it for me.
