edit: I didn’t word this very well, so I’ve added a picture and hopefully been a bit clearer…
I use Volumio2 on RPi3 in my car to create a hotspot wi-fi network so that my devices can connect and send music to the car via the RPi3’s 3.5mm audio jack. Unfortunately, the hotspot network seems to think it is online (i.e. has internet access, see image below). Therefore, my ios phone stops using its own mobile data connection and tries fruitlessly to access the internet via the hotspot (which obviously fails). As a result, my phone is unable to send and receive data via the mobile connection, which is no good on a long journey (traffic updates etc.).
Any ideas how to configure the volumio wifi hotspot to ensure it doesn’t declare that it’s online?!
