I’m using Xfce Debian. On other day, I was using Debian at lower battery % (< 10%). Then I started to face an issue with wifi. It work sometime but most of the time, I won’t. The issue was Debian (or Xfce?) aggressively enable the power saving options when the laptop is at low battery.

Run the following command to get the list of devices.

sudo iw dev

This returns a list of devices. Get the interface name from the output e.g. wlp2s0 or similar for wifi and check if power saver is on or off.

sudo iw dev wlp2s0 get power_save

You should see a result like - Power save: on. Turn off by running following command.

sudo iw dev wlp2s0 set power_save off
