                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
