Well, I had to try it…
@Nick_Craver I used to keep a USB-C adapter and USB Ethernet adapter in my go back for his exact reason.
And to test network connectivity without getting out a laptop, of course. 😂
I had a USB-C 10Gbit SFP+ adapter come across my desk. Of course plugging it into my phone was the first thing I did.
It was designed for Macs so idk if the drivers were extra weird but it didn't work. :/
