@TheGMan Also I wasn't sure about "Hardware version" or where to find that info so I put a "1" because thats what the firmware version started with and figured maybe that was an indicator of hardware...

My setup is Modem > Cat7 Ethernet > Main Router > Cat7 Ethernet > Main Deco XE75 Pro Unit > Cat7 Ethernet > the 2 other Deco XE75 Pro units. My gaming PC is connected to my main router via Cat7...
