I'm facing problems with WIFI on ubuntu
i tried to update the system but still the same
what happens is that i suddenly lose the connection with my router
and when i press on the WIFI bar the system won't detect any APs
i have to uncheck "enable WIFI" option ,then re check it so it work,it automatically reconnect.

I'm thinking of making a bash script that detects when the pc is disconnected from the router for any reason, and when it is disconnected it disable then enable the wifi.
i mean like automating resetting the connection that possible ?

i guess i must use this

nmcli nm wifi off

nmcli nm wifi on

but how can i make the script know if the PC is disconnected from the WIFI ?

It is more simple than you think:

#!/bin/bash



if ! [ "$(ping -c 1 google.com)" ]; then

    nmcli nm wifi off

    nmcli nm wifi on

fi

Then you can use a cron job for this script to run at every minute.
