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:

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 – susik Nov 28 '18 at 14:25
