How does this work with both? Is there a defined band plan standard that cable operators know to avoid? Do you need to install a notch filter on the line coming into the house?

MOCA modems looks for unused bandwidth

I think it just sits in the mutli-ghz bands. It shouldn’t conflict with cable, which uses lower frequency bands. You just gotta make sure to install a low pass filter at your demarcation point so you aren’t broadcasting your MoCA stuff beyond your home.

You also have to use appropriate splitters that are rated for the top ends of the spectrum.

Should I be surprised that the reactions posted here range from "I stretched a cable across the ceiling like two tin cans and a string" to "I will fly a drone into my attic". Instead of: "I took my $500k/year tech salary which I formerly spent on Teslas and cardboard apartments and just hired a competent electrician or other tradesman to pull cable to every room."

You should not be surprised. A lot of us are DIYers, and see no need to pay someone to do something we can do ourselves. Running low-voltage ethernet through an attic or crawlspace is within the skills of anyone with functioning limbs. There is zero reason to pay someone to do it. I don't really understand people who pay others to do every little thing they need done around the house, but I suppose they have differen…

Except the whole point of his post was that he didn't know how to do it competently, there's no way he wants to enter the crawlspace, so has resorted to wacky workarounds.

So, no, it clearly isn't within the skill (or desire) of anyone, but many would rather resort to hackery and hubris rather than pay someone to do it correctly.

I'll counter that and say there's probably minimum wage coders in India who write equal or better code than you at 1/10th of the pay, certainly possible as they have two functioning hands.

This is a comment for folks in homes with coax run for cable TV. Ethernet is great. I wired ethernet to most rooms in our remodel and set up wired access points or jacks in the office to connect directly to my computer. The speeds and consistency over wifi and mesh were remarkable. Especially consistency. We moved, and it's not feasible to run ethernet everywhere in our current home. However, whoever built the home r…

Oh, so you can connect several devices to the same "shared" coax cable around the house? How is it? Is it really 2.5gbps or is it like Powerline adaptors that are an order of magnitude slower than their advertised speed? :P

I can pull down a gig/sec no problem. Dunno how well it handles congestion or anything but it is way more than adequate for home use.

If you're willing to put the work in you can use the coax drops and runs as pulling line for cat, new coax (if you want to keep it) and real pulling line (to leave tied at the top and bottom of each drop if you ever need to run something else). Same idea if you have POTS copper run throughout. Most of the time even the ancient drops and runs have enough space cut out for a number of cables since doing runs is generally easier when the holes are larger.

Cool! I have the same issue with unused coax cables between every room, and was planning on replacing them with ethernet cables. In my case it's feasible without breaking down any walls. Does this work even with splitters?

Make sure your splitter is rated for like 1.8ghz so you don’t dramatically attenuate your signal. Cheap splitters will probably cause trouble.

What would we replace it with? Fiber? Quantum entanglement? Telepathy? Ethernet itself is the common-sense design you would arrive at if you needed to move bits from point A to B. Of course, things like the connector form factor could have evolved radically differently. Maybe in a parallel universe Ethernet uses something more like a unidirectional USB plug.

Reading you both...

I am 45. Last year, before I moved to a new house, I decided to run CAT8 Ethernet everywhere. Some people told me that they consider this excessive, but compared to the cost of the house, the extra cost was negligible and I hope this network will do well into the 2050s.

Maybe for plasterboard and timber construction. My house is mostly brick with the coax chased into the wall.

Are the two rooms on the same breaker/fuse (by some chance)? Another solution is ethernet-over-powerline where the data rides on your AC powerlines and is decoded at each end by an adapter. Supposedly they can get to the mid-hundreds of mbps, but only if they're on the same breaker. I used one in a rube-goldberg (Neighbor's WiFi)->(My Raspberry Pi, NAT Router)->(Ethernet-over-powerline)->(My WiFi Router) about 8 years ago, but the EoP was only good for a couple mbps because the signal had to go through the breaker. It was fine for poor-man's internet though.

Something that amazes me with Ethernet is how you can mix and match various cables and speeds and things do still work. Just for fun semi-recently I hooked a 10 MBit/s only hub (not even a switch, a hub) to a 10/100 MBit/s switch, to a Gigabit switch (that'd also work at 100 Mbp/s) and everything would just work...
