    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


## wifi-powersave-off.conf
# 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

## wifi-powersave-on.conf
# 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
	# 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
