Ethernet tethering with a USB-C adapter from my OnePlus 13 saved my ass last weekend as I had to restore a Proxmox backup of my OPNSense VM from a remote PBS, and obviously without it I didn't have normal internet connection at home.

Fantastic stuff. I wasn't sure if I'd have to set a static IP on my proxmox box in a predefined subnet, but nope Android spins up a DHCP server and everything is basically plug-n-play

I sometimes want to do the opposite (on my android phone) but I haven't figured out how without a USB to Ethernet adapter. Rhis is for when you don't want to create radio emissions.
