Other alternatives I've found to work are Ethernet over power (varies depending on how well your house is wired though) and ethernet over coax using MoCA adapters (if your house was previously wired with coax for cable TV these work great)
G.hn is fast, but all of the G.hn devices I've found seem to use the same chipset (and presumably similar firmware, since the configuration pages have identical options, but different branding), and the chipset seems to buffer a massive amount, which means a single hiccup while using a high-bandwidth application makes the network unusable for a while.
Example: while streaming video over a G.hn adapter, I was running ping. There was a brief hiccup, and then ping times exceeded 20 seconds (!!), finally recovering after a few minutes. I eventually ran a program that ran on devices connected to each side and would reboot the adapter if ping times exceeded 500ms. This made the network far more reliable.
The problem with P/L is that it can work, until suddenly it doesn't.
I ran a set of TP-Link powerline at my last 2 places: in both, I rented a room in shared flats (apartments).
In the first I got a very poor intermittent wifi over 3 floors from my landlord's wifi: 2-5 Mb/s if that. With powerline I got a consistent 60-70 Mb/s.
Yes, they needed rebooting regularly, but it was totally worth it.
2nd place, here in Prague, I bought new units, because the tech had updated. My old landlord still uses my old setup as a wifi repeater, over 4Y later.
New place, my flatmates had put Ethernet across the floor, so it was in very poor shape: walked on, trapped in doors, insulation frayed, etc. Connection was very intermittent.
In that place, powerline allowed me to remove the messy dangerous ugly cable and gave me a steady reliable 200-250 Mb/s connection.
I think the complaints here may be from Americans who are famous for having mains power like wet string, running at half the voltage of the rest of the world. Across Europe it's all 220V, with mandatory earth (ground) pins, and every dwelling is on a separate ring main, so nothing your neighbours do affects your home and there is zero leakage.
Also, electric kettles work, and as I run on tea, that's important. :-D
I could have put Ethernet in, but adding a wire under the floor was vetoed in the interests of not making a mess.
Don't listen to them! Run that Ethernet!
It would be pretty expensive to turn every coax run in my house into a hardwired ethernet switch but well placed hardwired APs obviates the need to do that.
This is assuming you have coax rg6 or better already in the wall
In my case, I didn't build a MoCA network, just used these devices point-to-point. If you go full MoCA, think of it like a distributed hub - no switching, no routing, no security. In fact you should put filters to prevent neighbors from listening in using their own MoCA adapters. For me, point-to-point worked. YMMV but Ethernet over Coax is definitely worth looking into for upto 1gbps speed, which is plenty for wifi, netflix etc.
Wow. Who knew that inbound cable internet has outbound data capability? Thanks for posting.
Is this a suitable filter (-70db)? https://www.amazon.com/GLP-1G70CWWS-Filter-Eliminate-Multi-R...
The physical medium isn't directional, so there's no reason to assume it would not transmit and receive. A coax cable is equivalent to three wires with better isolation from the environment (and with one "wire" usually used for ground).
There's an asymmetry in commercial broadband over coax, but Im not sire why that is precisely. Perhaps someone familiar with DOCSIS etc. could say.
Ethernet runs are cheaper in parts, but MoCA adapters are crazy effective at avoiding large drywalling jobs.
