Yes, that worked. Thanks much. I will say however, following your instructions closely, the uninstall of the "default" I210-T1 adapter never did stay uninstalled across a reboot. After doing steps 1 - 4 and rebooting (#5), the default I210 adapter again appeared in device manager. This time, when I went to uninstall it, there was no check box to delete the adapter, just the uninstall button. I did the uninstall and rebooted a 2nd time. Again the default adapter was back, so I did the uninstall (no "delete" check box) without rebooting and proceeded with the install of the downloaded driver package. It worked fine, and the device manager shows a driver version 12.18.9.1, dated 6/13/2019. The key seemed to be the uninstall of the Intel Network Connections in the Apps and Features section of the Windows settings.
