I originally used an old Android phone to create a wifi hotspot with SSID Chordata-net and password. Then on the laptop using Blender, I connected to the wireless network Chordata-net as well.
However, I am then disconnected from the internet on my laptop and cannot view this page or search for anything. So I have changed the wireless settings on the Raspi to connect to the wireless router instead of the hotspot. That also allows the Raspi to connect to the internet, and on the laptop I can connect to the Raspi and the internet at the same time.
But we have the Android hotspot configured should we need to use a private network entirely.
