I connected the same UTP cable at the same location in the network where the Zidoo is connected to an older laptop and did an internet speedtest. It was shy 60 mbps going at 225 mpbs average compared to my much faster desktop. Since I know I didn't have nearly this many issues with the Z9S and the Dune also works mostly fine (besides not wanting to play Tenet UHD) I'm going to send it back and ask for an exchange. When I receive the new one I'll let you guys know if the situation improved. Thanks everyone for all the help. I did learn much more about networks this week.
