Teclast Air III Android + Ethernet

Welcome to the forum

I don't know of any USB-Ethernet adapters that have Android drivers. The answer is probably no.

I can actually use USB to Ethernet with my old Ramos W28 that has the Android 4.2.2 (latest one until they stopped giving updates).

Works fine with a $2 USB to Ethernet adapter that I bought from China. Don't know what chipset it has.
