$100 to connect 2 drops. Plug it in and it works. (change the admin password tho!) https://www.amazon.com/Hitron-Ethernet-existing-Backbone-Str...
If you have 5 or less, it shouldn't be an issue.
But yes, it would not necessarily work great in something in like an apartment.
Additionally, >1Gbps is starting to become common on consumer hardware.
Again, it is probably not going to be a concern for most home networks, and MOCA should still be better than mesh networks or powerline ethernet.
As a bonus, if I (or the next guy) wanted to have a landline phone, it's in the same closet and it can be patched to anywhere in the house by swapping a single wire.
Given the opportunity, even after the house is complete, it's a very useful thing to do.
When building new,
Running 2-4 Ethernet cables to each room is a must and cheap. Kitchen islands, garages, you name it. Between different devices, multiple Vlans, being able to run PoE equipment, it’s indispensable. Helps avoid a lot of small switches.
Security cameras if they are your thing should ideally be poe and avoid wifi.
There are some good Ethernet to HDMI adapters as well so prewiring ceilings with a double run for projector plus Ethernet doesn’t hurt.
It also makes it easier to experiment with Linux, etc.
Now I can keep heat-generating stuff like my storage server and the cable modem (surprisingly heat-intensive) in the basement, have a WiFi AP in the attic for great coverage in the yard, and I can easily drop lines down into rooms on the 2nd floor from above by just drilling a small hole in the top of a wall and feeding the Cat6 down, or put one into a 1st floor room by going up from the basement. Cat6 anywhere I want it, basically.
It's something I've wanted for years and held off doing because I knew I was capable of DIYing it, and therefore I hesitated to hire it out. This was dumb.
It took him an hour or so using various specialized tools ("fish bits", "fish tape", tall ladders, drywall saws, etc.), when it would have probably taken me the better part of a weekend and I wouldn't have done as clean of a job. He also knew from experience where the easiest place would be to get all the way from the basement to the attic, given my house's construction style.
Definitely worth the two bills, and also now I have a "wiring guy" for future projects. I've already called him back to help run wiring for PoE outdoor cameras, another thing I've wanted for years but haven't bothered to execute on.
