I found this option in the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf :

wifi.powersave = 3

But couldn't find detailed explanations about that in the manpage:

wifi.powersave
If left unspecified, the default value "ignore" will be used.

I noticed that my Wi-Fi signal sometimes goes down even if the modem is near my laptop.Can that option cause this behavior ? And also does that have an impact on speed? (because of the packet drops due to low signal intensity)

And what does 3 mean in that option?

Thanks.

Possible values for the wifi.powersave field are:

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

    Thank you for your answer! For future reference, the appropriate action when an answer to another question on Unix.SE is relevant, is to suggest it as a duplicate, not copy the information. – Stephen Kitt Sep 16 '20 at 09:07
