I have an issue with Ubuntu 18.04 and closing the lid of the laptop. rather with loosing internet connection when the lid is closed. I noticed that machine does not even respond to ping when the lid is closed. I've setup Power manager to 'ignore' closed lid. I reconfigured logind.conf but it did not have an effect.

Could someone please advice how to keep wi-fi connection when the lid is closed? Note:I did not have the issue with 16.04 Thanks

Ive had the same issue before. This is an easy fix:

Edit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf with your editor of choice. This will require sudo.

Find the following line:

[connection]
wifi.powersave = 2

Change the 2 to a 3

Save the file and exit.

After saving type:

sudo systemctl restart NetworkManager

  • Hi Keltari. Thanks for suggestion. I checked the file and the value was already 3. Any other suggestions? Thanks

Try https://tipsonubuntu.com/2018/04/28/change-lid-close-action-ubuntu-18-04-lts/

It worked for me on 20.04LTS

  • There is a new entry there called HandleLidSwitchExternalPower. I had to set this one to "ignore". The other solutions did not work. I had this for Ubuntu 23.10 as well as Debian 12/Bookworm.
