I don’t have ethernet to my office on the second floor of my home but there’s a coax line we don’t use.

Ordered a moca kit. Traced out all the coax. Took off the splitters and made it a straight shot to my living room.

Upstairs I made an Ethernet cable to tack along the wall around to my office/gaming rig.

2.5 gig moca adapter.
Like 900 up and down to ethernet.
