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
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
Thnaks for this, used for my connection and latency in ssh sessions seems to be imroved:
CONN="my wifi conn"; nmcli con mod "$CONN" 802-11-wireless.powersave 2
