Can I connect to two different WIFI?
In other words: Connect to WIFI A and if it´s not reachable connect to WIFI B and if it´s not reachable start the Patchbox hotspot.
Linux systems does not seem to provide a list of once detected/connected WIFI´s?
The part that enables the hotspot won’t be possible without scripting.
I don’t think there’s a ready and easy solution that does what you’re after, you’d probably have to script the entire logic sequence yourself.
so I put the other Network in my /etc/wpa_supplicant/wpa_supplicant.conf and hope it will connect to the available one.
