Advanced Wifi Options for powersave mode

[mietzen]

Describe the feature

I would like to have a feature to set the powersave mode of the wifi card permanent.

Use cases

When I set the powersave mode to off, via:

$ nmcli connection modify "Supervisor wlp4s0" 802-11-wireless.powersave 2 && nmcli connection down "Supervisor wlp4s0" && nmcli connection up "Supervisor wlp4s0"
Connection 'Supervisor wlp4s0' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/4)

My ping / jitter get's significantly better:

Current workarounds

On every host reboot I need to run: nmcli connection modify "Supervisor wlp4s0" 802-11-wireless.powersave 2 && nmcli connection down "Supervisor wlp4s0" && nmcli connection up "Supervisor wlp4s0"

Anything else?

It would be fine for me to make this a ha network option, like ha network update --wifi-powersave 2. I don't need a web gui option. I would also be fine opening a PR for this if someone could give me a hint where to start.

[agners]

Hm, I wonder if it would make sense to simply default to disabled for powersave mode, since we are a Server by default 🤔

@sairon thoughts?

[mietzen]

This would also work for me 👍

Edit: I also wondered in which kind of situation power save mode would be a valid choice when running HA OS

[sairon]

Right, let's make it default: home-assistant/operating-system#4529

[kachkaev]

A follow-up fix is still needed: home-assistant/supervisor#6751
