Wifi breaks when waking from sleep | Linux Mint Community🍵 | Page 1

#

today my wifi started breaking when i exit from sleep.
if i ping a url it will error with "network is unreachable", then if i either restart my router or make mint forget the network and reconnect everything starts working again.
i know the problem isn't my router because mint is the only place where this happens.

#

wifi power saving is 2, so that shouldn't be a problem

what wireless chip is it

Chipset is from Intel

#

Weird since iwlwifi is a surprisingly decent wireless driver

#

I suspect some ACPI fuckery to be the issue, is this a laptop?

this is after i wake when connected to my router, wifi no longer works

#

if you see anything about switching networks thats cos i switched to my hotspot accidentally and then switched back to the broken router connection before running the command

which is the only other option in the dropdown

sullen iris Mar 22, 2026, 12:12 PM

6.14 is your default image

#

Go to the grub menu (press esc once after you see the manufacturer's logo after POST) and select the 6.17 image in advanced options

#

If it's not a troubling kernel, go to the update manager and delete all 6.14 kernel packages, which will set the default image to the one you're currently running

perhaps your router got a firmware upgrade that breaks some connections?

according to the app (for of course i need an app for it) the modem is "up to date". i am also unable to roll back an update as it is all handled by the provider

you don't have the standard kernel either

virtualbox goddamnit

#

virtualbox's kernel driver doesn't work with 6.17

#

so your nvidia modules also don't get built

cursive vessel Mar 22, 2026, 1:24 PM

i've been having trouble with virtualbox's updates now that you mention it

sullen iris Mar 22, 2026, 1:24 PM

are you open to remove it?

cursive vessel Mar 22, 2026, 1:25 PM

every time i go to update anything it errors about failing to update virtualbox, the rest of the updates seem to go through

cursive vessel Mar 22, 2026, 1:25 PM

#

sullen iris are you open to remove it?

i mean, sure

#

i can just reinstall no?

sullen iris Mar 22, 2026, 1:25 PM

#

i've learned that virtualbox is not ideal on linux

sullen iris Mar 22, 2026, 1:25 PM

#

cursive vessel i can just reinstall no?

only if your kernel is 6.8

#

which is the kernel the driver was tested on apparently

cursive vessel Mar 22, 2026, 1:26 PM

#

that's way older than what i have

#

is virtualbox really that shit

sullen iris Mar 22, 2026, 1:27 PM

#

mostly

cursive vessel Mar 22, 2026, 1:27 PM

#

cringe

sullen iris Mar 22, 2026, 1:27 PM

#

we can look into alternatives that use Linux's native virtualization

cursive vessel Mar 22, 2026, 1:27 PM

#

i tried out qemu but i know diddly squat about virtualization so i gave up after i needed to run two daemons just for the thing to crash anyways

#

whatever, problem for later

#

wifi is more important

sullen iris Mar 22, 2026, 1:28 PM

#

so sudo apt purge virtualbox virtualbox-dkms && sudo apt autoremove

cursive vessel Mar 22, 2026, 1:29 PM

#

oof autoremove scares me

#

i really don't want to get into another situation where i can't boot the os

sullen iris Mar 22, 2026, 1:29 PM

#

you can omit it

cursive vessel Mar 22, 2026, 1:29 PM

#

a friend of mine has a similar gpu and every time he runs autoremove it uninstalls his drivers

sullen iris Mar 22, 2026, 1:30 PM

#

then you can just do the purge

cursive vessel Mar 22, 2026, 1:30 PM

#

sullen iris you can omit it

oh alright then

#

ig i'll try

sullen iris Mar 22, 2026, 1:30 PM

#

then 6.17 should automatically install

cursive vessel Mar 22, 2026, 1:31 PM

#

never thought virtualbox could be the cause

sullen iris Mar 22, 2026, 1:31 PM

#

third party untested drivers ¯_(ツ)_/¯

cursive vessel Mar 22, 2026, 1:36 PM

#

okaaay so apt list | grep nvidia returns 17223 lines

#

that doesn't seem right

#

how do i determine what i need?

sullen iris Mar 22, 2026, 1:37 PM

#

does 6.17 install first?

cursive vessel Mar 22, 2026, 1:37 PM

#

oh i haven't uninstalled vbox yet

sullen iris Mar 22, 2026, 1:37 PM

#

cursive vessel okaaay so `apt list | grep nvidia` returns **17223** lines

append --installed to apt list

cursive vessel Mar 22, 2026, 1:38 PM

#

sullen iris append `--installed` to `apt list`

ok that's much more reasonable

cursive vessel Mar 22, 2026, 2:20 PM

#

alright everything seems to have worked

#

now to see if the wifi still dies

#

yep! still fucked

sullen iris Mar 22, 2026, 2:41 PM

#

are you on the newest kernel?

cursive vessel Mar 22, 2026, 2:46 PM

#

6.17 right?

sullen iris Mar 22, 2026, 3:03 PM

#

yes

cursive vessel Mar 22, 2026, 3:07 PM

#

then yes i'm on the new one

and vbox is no longer installed

sullen iris Mar 22, 2026, 3:17 PM

#

hm

#

the problem appears to have fixed itself.

sullen iris Apr 6, 2026, 9:33 AM

i think your AP was at fault then
