MoCA 2.5 Networking

Thought I would do a very quick write up on my MoCA experience in a 20 year old house that only has coax in the walls, no cat5e.
I wanted to bring networking to the attic, where I planned to place a PoE switch and an NVR. From the attic, I had already ran some network cabling to the ground floor, for a WiFi AP, and the same for the upstairs in order to get good WiFi coverage throughout the house. The problem was, any internet service I have, comes in to the office, which is downstairs. Other than using existing coax, the only solution would have been to run the network cable from downstairs to the attic externally, which while doable, would have been a bit of a pain.
Unfortauntely, the coax that was in the walls, was of unknown quality, as it had no markings, just a generic white cable. This did have me a little concerned that I may not get great speeds, but I thought it was worth a gamble. I verified continuity between the downstairs coax and a coax I had found in the attic, which showed 0.6ohm resistance, which was not a terribly conclusive test, but at least showed that there was a chance it would work. I purchased a set of MoCA adapters from Amazon and would you believe it, it just worked out of the box!

I tested the speed, between two laptops, and was pleasantly surprised (considering the coax quality), that it maxed out the NICs on both machines at 1Gb. Success!
I can now easily install the two APs (some old Ruckus R510 from eBay). All of the above work meant that I haven't had to open a single wall to run the cabling, meaning for quite a neat install. I've tested WiFi in the house, with just one AP and it is significantly better and more consistent already, when compared to the existing Asus router WiFi I was using.
Not much purpose to this post I suppose, other than to potentially let people know that MoCA is worth consdering as a somewhat easy solution that may just work. Its a shame that there isn't many retailers selling these units in Ireland/Europe. Seems to be very common in the states, and more affordable also (you can get a single adapter for as cheap as 30$, versus 130e for two in Ireland).
