Why does my wifi networks dissappear when my screen sleep/suspends on 24.04.1?

  • 772

I just dual booted to 24.04.1 on my laptop. Whenever I open ubuntu I connect to wifi like usual. But when my screen sleeps or it enters suspend, whether I close it or it auto-sleeps, all networks just dissappear.

I've tried:

  • sudo systemctl restart NetworkManager

  • Changed wifi.powersave to = 2

  • sudo apt update && sudo apt upgrade

  • Ran: sudo nano /lib/systemd/system-sleep/restart-network-manager.sh Created script: #!/bin/sh case $1 in post) systemctl restart NetworkManager ;; esac and then sudo chmod +x /lib/systemd/system-sleep/restart-network-manager.sh

  • Updated drivers sudo ubuntu-drivers autoinstall

  • Checked rfkill list; not blocked btw

All networks still disappear after suspend. It's like it's looking for networks but just never finds it

Ideas anyone?

    So the answer was like @david said to make the screen sleep. I'll go through it step by step for the complete beginners as well:

    Enter terminal(Ctrl + alt + T by default):

    Enter sudo nano /etc/systemd/logind.conf

    sudo triggers you to write your password so write it and press 'Enter' to open the file

    Find the line: #HandleLidSwitch=suspend

    Remove the #

    Change the line to HandleLidSwitch=lock

    (Optional) I changed HandleLidSwitchExternalPower and HandleLidSwitchDocked as well so it works when its connected to an external screen or charging too

    Then you press "Ctrl + X", press "Y", and then finally press "Enter"

    NOTE: The next step will restart the pc. Save anything you need to be safe. When you run the command the screen will turn black, then show lock screen and after you've logged in it will show black again. To return to normal press Ctrl + C.

    Restart by writing : sudo systemctl restart systemd-logind

    And now it should work!
