Can I somehow connect that so that I have internet? And how does it work?
I don't know if all computers work. But mine is via hotspot.
I guess you use Windows. Go to the properties of your network adapter and click on Sharing. You will be helped there.
The computer can be connected via a LAN cable
or via settings Ethernet
You can do this with a smartphone, but via a SIM card and there are laptops with a SIM card slot.
