Suspension on my laptop (closing the lid) causes Wifi to not be available.

RossoErcole@kbin.social to Linux@lemmy.ml – 29 points –

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

I'm not sure what the question here is. Are you wondering which level of suspension you want your laptop to go into when you close the lid?

You should understand ACPI sleep states when trying to setup whatever active states you want your machine to be in when you close the lid, because there is a chain of events that happen when you do so. Your machine may only support one, or a few states (s0-s3) that may not allow this. The first step is above, and the second is understanding what state your machine is being put into once you close that lid, so start there with Mint configuration and how it's dealing with the lid closing.

I believe they're saying that when come back from suspension, the wifi doesn't work until they reboot.

I'm not sure, but there is a Power Managment menu in Cinnamon and I have creenshots:

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

you have to replace the ## with &&

the name should be iwlwifi

how do I check the name? because iwlwifi doesn't work

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
rmmod: ERROR: Module iwlwifi is in use by: iwlmvm
modprobe: FATAL: Error running remove command for iwlwifi

yes of course

sudo modprobe -r iwlwifi

I've tried. After suspension but before modprobe the wifi is not available, after modprobe it is there, but is disabled and cannot be enabled.

So I don't know :-(

Have you disabled Fast Boot in your BIOS ?

It was but it got reenabled, I disabled it again but it still doesn't work damn. I'll post the Intel I gathered on the Linux mint forum (I did in the past but now I have more information)

Is your laptop, by any chance, an HP? I had the same issue with wifi and finally, after about a year of frustration, found the solution HERE. To save a click, here's the part that worked for me, with the disclaimer that I don't honestly know how this works, but by the time I found it I was frustrated enough to run random code from the internet with sudo privileges on my main machine:

First, create the file

/etc/systemd/system/hp-keycodes.service

and type/copy-paste the following into it:

[Unit]
Description=HP setkeycodes fix

[Service]
Type=oneshot
Restart=no
RemainAfterExit=no
ExecStart=/usr/bin/setkeycodes e057 240 e058 240

[Install]
WantedBy=rescue.target
WantedBy=multi-user.target
WantedBy=graphical.target

Then, run the following commands:

sudo systemctl daemon-reload
sudo systemctl enable --now hp-keycodes.service

That fixed it for me, hopefully it helps you (or someone else) as well!

no I have an MSI, but I hope in some ways this script helps people that might know more about it.

Looking at the Arch Wiki, it looks like this is a known issue. Give this solution a go:

https://wiki.archlinux.org/title/MSI\_GS65#Wifi\_is\_hardblocked\_(airplane\_mode)\_after\_waking\_up\_from\_suspend

EDIT: on closer look, it's not much of a solution. I assume you've tried restarting the network service and that doesn't work either? Possibly you could automate the airplane mode key twice by triggering that after waking from suspend....

I've thinkered with this problem in the past, so I believe I did try restarting the network service, but I'm not sure I did

Do you have Nvidia GPU? I am not sure if that could be related, but sometimes my old laptop would behave funky after resuming it from sleep when using nouveau driver. Although generally I just wouldn't get any video output. But I could never get past login screen, and it sounds unlikely it would affect WiFi, but who knows?

Yes I do, 1070, I've posted more details of my system in an answer and in the main thread. But I use the proprietary drivers not nouveau

It's been a while, but if I recall correctly Linux has always had issues with resuming from suspend. I would set it to not suspend, make closing the lid do nothing.

Mhm, but it doesn't sound great. If you forget it's on, you put it in a backpack to then get it out at around 300 degrees. Sounds like a very bad idea.
