Thank you, Sholander and The Coolest. You guys pointed me in the right direction. I guess the T95Z had a hardware issue or something with the Ethernet port. The information led me to a command to limit the ethernet speed. Everything works now (still fighting to get the VFD working though) with LAN.
Even though I limited the ethernet to 100M, I'm getting faster than 100M speeds and can now stream files without buffer/stutter. So all seems to be well.
