Wifi automatic power-on/off at set times

[alimurgia]

Hi everyone!
I was trying to auto power-on/off my WIFI connection on Manjaro Gnome at set times (something like some Androids have) but I do not find any solution.
Any hint?
Thank You

Hi @alimurgia,

If you know the command, you could create a systemd timer unit, both for disabling and enabling the device.

I don’t know if this is the best way, or even a good way, but it is

@alimurgia

Any hint

Hope this helps!

nmcli
You can write a small bash script.
On KDE, you could set an event in KAlarm to run the script to enable/disable it.
You need to schedule nmcli radio wifi off and nmcli radio wifi on

You could use a cron job, or a simple alarm to run a script.

You could also set a timer in your terminal… I don’t use Gnome though.

I would do this:

#!/bin/bash

commands () {
echo WiFi OFF
sleep 1; date +"It's now %R" | cowthink

echo "How long until turning off WiFi?"; read TIME

echo $TIME set!; sleep $TIME; nmcli radio wifi off
}

export -f commands

konsole -e "bash -c 'commands'"

Make it executable, and drag a shortcut to a panel.
Or, move it to your PATH and call it ‘Timer-WifiOFF’.

You could do a similar script with no timer…

#!/bin/bash
nmcli radio wifi off

Here’s now KAlarm sets my RTCWake to wake up my computer in the morning before my wakeup alarm…

Or combine this with a systemd timer. They’re quite easy to make.

best solution ever!

Haha yes, I looked at systemd timers and - well a few steps needed.

Or, perhaps, a slinky GUI

[Mirdarthos]

Or you can do it like I like doing it. Manually creating the file:

It might sound complicated, but it’s actually easier than cron jobs according to me.

@Ben

Or, perhaps…

…a Gtk GUI

Yay - well not quite so GUI as I’d hoped… but I got it sorted.

1. Created script ~/bin/rtcwake0600.sh

#!/bin/bash
echo MYPASSWORD | sudo -S rtcwake -m no -l -t $(date +%s -d 'tomorrow 0559')

2. Mkdir and CD ~/.config/systemd/user/

rtcwake.service

[Unit]
Description=A job to set rtcwake with a systemd timer

[Service]
Type=simple
ExecStart=/home/ben/bin/rtcwake0600.sh

[Install]
WantedBy=default.target

rtcwake.timer

[Unit]
Description=Schedule rtcwake every morning
RefuseManualStart=no
RefuseManualStop=no

[Timer]
#Execute job if it missed a run due to machine being off
Persistent=true
#Run 120 seconds after boot for the first time
OnBootSec=120
#Run every 30 minutes
OnUnitActiveSec=1800
#File describing job to execute
Unit=rtcwake.service

[Install]
WantedBy=timers.target

And because these timers are kind of invisible, I added a conky entry:

rtcwake: ${execi 3500 ~/.local/bin/sudo-rtccheck.sh}

And the script to check and display is:

#!/bin/bash
echo MYPASSWORD | sudo -S rtcwake -m show -l -v |rg alarm: | cut -c 12-30

ROFL quite a bit of messing, and much worse than having a simple option to click the clock - set an alarm/timer, select an option to wake up the machine if it’s off etc… but oddly satisfying

How did it go with the Wifi?
