usb-c to lan adapter not working on MacBook Pro 2018

I had several of these working, something glitched out and now none of them work. I cannot get any level of networking over the usb-c dongles. The lights light up Green/orange on adapter light up/blink In Network settings, put on DHCP, I get a self assigned IP. If I then set it up manually I do get the green dot in the system panel, indicated all is connected, but I do not get data In System report, under hardware I have the USB 3.1 and under one of them I see the Realtek lan adapter or any other similar device I connect. NO usb networking works. I normally was able to ping my local interface but with a self signed interface it still cannot ping. Any thoughts on what I am missing here? wifi works fine but I use my mac versatily to troubleshoot all manner of networking problems.
