What a timely thread to find. We moved into a new house in October. The builder ran CAT5E and Coax to each of the main rooms, but of course didn't terminate it behind the wall plates or in the basement. I spent an afternoon terminating each end and of course complaining to myself about why they didn't run CAT6 in 2022 when they built the house.
Anyway, I'm working on finishing the storage and workshop space in the basement where everything terminates and here's where things currently stand.
1GB Fiber is awesome, paired with the (3) Eero Pro 6's hardwired throughout the house (~3000sqft) basement + main level all getting managed through a TP Link Switch. Drywall and low voltage covers coming soon. I'll likely run myself a few more Ethernet lines to various areas of the house before I cover up the wall.
