Wi-Fi toggle

:!: There is a package called wifitoggle that does the same thing as the scripts below but is more advanced and has configuration. See Wifi ON OFF buttons

The scripts below allow the use of the SES button to enable or disable the wireless, this is achieved by adding a hotplug handler which reacts on button press events and a toggle script which enables or disabled the wireless depending on the current state.

Note: If you are using wireless encryption, nas and radius daemons will not be turned off during toggle and will continue to occupy CPU/memory. They should not consume too many resources with no client load though.

Toggle script

New script

:!: This new revision aims to fix the issues previously noticed with the old script. It also uses the commands wifi up and wifi down that are supposed to be the right way to turn on or off the device.

cat << "EOF" > /sbin/woggle
#!/bin/sh
 
device="wl0"
case $(uci get wireless.$device.disabled) in
    0)
        wifi down $device
        echo 0 > /proc/diag/led/ses_white
        echo 2 > /proc/diag/led/wlan
        echo 1 > /proc/diag/led/power
        uci set wireless.$device.disabled=1
 
        echo "Wifi disabled"
    ;;
    1)
        uci set wireless.$device.disabled=0
        wifi up $device
        echo 1 > /proc/diag/led/ses_white
 
        echo "Wifi enabled"
    ;;
esac
EOF
 
chmod +x /sbin/woggle

Don't forget to change the value of device according to your case.

Old script

cat << "EOF" > /sbin/woggle-old
#!/bin/sh
 
case "$(uci get wireless.@wifi-device[0].disabled)" in
    1)
        uci set wireless.@wifi-device[0].disabled=0
        wifi
        echo 1 > /proc/diag/led/ses_white
    ;;
    *)
        uci set wireless.@wifi-device[0].disabled=1
        wifi
        echo 0 > /proc/diag/led/ses_white
        echo 2 > /proc/diag/led/wlan
    ;;
esac
EOF
 
chmod +x /sbin/woggle-old

Hotplug handler

To get hotplug working, run the copy-pastethe code:

mkdir -p /etc/hotplug.d/button
cat << "EOF" > /etc/hotplug.d/button/01-radio-toggle
if [ "$BUTTON" = "ses" -a "$ACTION" = "pressed" ] ; then
        ( sleep 1; /sbin/woggle ) &
fi
EOF

Now, every time you want to turn the wireless on or off, you can press the button on the router, or you can issue a woggle command from the OpenWrt shell.
