u/No-Abbreviations4194

I’ve been reading up in the Q&A and online and I’m struggling to grasp the right way to do this so I can use a Coax hookup in my living room (1 floor above and across the house) for gaming.

The first 2 photos are in my basement and have the Verizon modem and splitter for Coax and then have my Google home router attached out of a Ethernet port 1 floor above.

Do I leave the blue Ethernet in the black box and then attach a coax to the black box and the “in” function of the splitter?

Or should I attach it at the Coax point in photo 4 and then to the modem?

Apologies if it’s not super clear
