That is fascinating, thanks for the link! Hopefully I'll remember that if either of my USB/Ethernet adapters seems to be related to a network problem. Sometimes I think USB-C hubs are simultaneously the best thing ever, and the bane of my existence. I'm finally happy with the CalDigit one I use now, but it took a couple attempts to find something that didn't have some glaring problem. One of my MacBooks just uses a plan USB->Ethernet adapter successfully, but that's because I don't need it to do anything more complicated.
