NetworkManager Wi-Fi powersaving configuration

NetworkManager WiFi Power Saving

NetworkManager supports WiFi powersaving but the function is rather undocumented.

From the source code: wifi.powersave can have the following value:

  • NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
  • NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1): don't touch existing setting
  • NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave
  • NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3): enable powersave

Then I propose 2 files, only one of them needs to be put under /etc/NetworkManager/conf.d/.
One is forcing to disable powersaving, while the other one enable it.

Once you have put the file in the right folder, simply restart NetworkManager:

sudo systemctl restart NetworkManager
# File to be place under /etc/NetworkManager/conf.d
[connection]
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
wifi.powersave = 2
# File to be place under /etc/NetworkManager/conf.d
[connection]
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
wifi.powersave = 3
