No IP over WireWorld Platinum Starlight Cat8

I’m having some problems with what I thought would be an easy setup.  I have an AQVOX switcher on order but it won’t arrive for another few weeks.  When it does, I will bring it into the system...mirroring the suggestions of  audioengr.  In the meantime, my notes below are based on a temporary setup.

STREAMER: Aurender A10 https://www.aurender.com/page/a10
ROUTER: https://www.netgear.com/orbi/default.aspx (Orbi)
ETHERNET CABLES: Platinum Startlight Cat8 http://www.wireworldcable.com/hi-res-digital-audio-cables.html#ethernet

When I first received the A10, I did not have the WireWorld Platinum cables yet, so I used a basic ethernet cable included with the Orbi router.  Works just fine, directly connected from Orbi router/modem combo, no issues.

Upon receiving the WireWorld cables, I inserted them into the mix, direct from the Orbi to the A10.  No IP detected.  I tried putting an Airport Express (client mode) between the Orbi and the A10 but still, no IP detected.  I tried an Eero, also set in bridge mode and the WireWorld cables do nothing.  Insert cheap cables and boom, all is working.

Can anybody explain why the cheap ethernet cable works perfectly with a direct connection to the A10 but the high-end cables do not?  Thoughts on settings?  Is there something I'm missing?

Thanks!
