"Apparently the eqipment I have is a WiFi-6 multigig fiber optic gateway made by CommScope and is used by Ziply. So, might the TP-Link Deco XE-75 work asa replacemen? <https://www.tomsguide.com/reviews/tp-link-deco-xe75>"
If I'm understanding all of this thread thus far correctly, you seem to be suggesting replacing a "fiber optic gateway" with a "WiFi Mesh Router." Color me confused. Firstly, you said you didn't need WiFi support and secondly the TP-Link isn't a "fiber optic gateway." Why not just see if you can buy the Commscope Homevantage fiber gateway? However, it seems to be marketed to Service Providers. Maybe Zipley will sell it to you outright. Heck,it even runs OpenWRT!
