If your house has coax in the right two rooms, MoCA is the best value in home networking. If it does not, the adapters are useless. Everything depends on four questions.

Yes, if there is a coax outlet in both of the rooms you need to connect and they are fed from the same splitter. In that situation a pair of MoCA adapters is the cheapest reliable gigabit-class wired link you can add to a house without drilling, and it beats every wireless option outright. If either half of that condition is missing, the adapters do nothing at all.
MoCA stands for Multimedia over Coax Alliance, and the idea is simple: your house probably has shielded coaxial cable running to the places televisions used to live, and that cable can carry Ethernet. One adapter at each end turns two coax outlets into two network ports.
The four questions
Is there a coax outlet in both rooms? Behind the television, next to the router, in the basement. If the answer is no in either room, stop here — this is not your fix.
Are those outlets on the same splitter tree? Usually yes in a house wired for cable TV by one installer. If the two rooms were cabled separately and never joined, the adapters cannot see each other.
Do you actually need a wire there? MoCA is a backhaul and a wired-device fix. It does not create Wi-Fi — you still need a mesh node or access point at the far end to turn that port into coverage.
Could you run Ethernet instead? If a cable route exists and you are willing to use it, do that — it is cheaper and faster. MoCA exists for the houses where that answer is no.
Your situation
Is MoCA worth it?
Why
Coax behind the TV and near the router, mesh backhaul needed
Yes — the strongest case there is
Removes the wireless relay penalty completely for the price of two adapters
Rented house, no drilling allowed, coax present
Yes
Nothing permanent changes; the adapters come with you
Console or TV in a far room with a coax outlet
Yes
A wired, shielded path with none of the jitter a repeated radio adds
Fiber-only home built without coax
No
There is nothing for the adapters to talk over
Two rooms, no coax in one of them
No
Try powerline, or an access point on a cable
You can run Ethernet in an afternoon
No — run the cable
Cheaper, faster, and no adapters to power
When MoCA is worth it, by situation. The pattern is that it wins wherever coax exists and a drill does not.

What you get, concretely
Bonded MoCA 2.0 adapters top out around 1 Gbps, which is everything a gigabit-or-slower plan needs. MoCA 2.5 adapters sit in the 2.5 Gbps class, which matters only if your plan or your internal transfers exceed a gigabit. Both are shielded, which is the real advantage: unlike powerline, MoCA does not care how old your wiring is or what else is plugged in, because coax was built to carry high-frequency signals and your house mains were not.
Three things to budget for beyond the adapters. First, they are sold and used in pairs — one adapter alone does nothing. Second, you will usually want a point-of-entry MoCA filter, a few dollars, fitted where the coax enters the building: it keeps your network signal inside the house and stops it leaking onto the provider's line. Third, each adapter needs a power outlet and takes up space behind whatever it serves.
If your provider supplies cable internet over that same coax, the adapters coexist with it — MoCA uses frequencies above the ones DOCSIS uses. The filter is what keeps that arrangement tidy. The full mechanics are in MoCA adapters: coax as your backhaul.
Try this first
The highest-value use of a MoCA pair
Wiring the backhaul of a cheap dual-band mesh system. That system is giving up about half its throughput at the far node to the shared backhaul; one MoCA pair removes the penalty, and the combination of a budget three-pack plus two adapters outperforms a premium two-pack running wirelessly in most houses. How wired backhaul works has the detail.
When it is not worth it
Newer houses built for fiber frequently have no coax at all, and some apartments have exactly one outlet. If that is you, the honest options are powerline, which is a lottery on your electrical installation, or an extender or access point. And if what you actually have is one weak room rather than a backhaul problem, the cheaper alternatives to mesh is the page to read first.
How we picked
We do not run a test lab. Rankings here are built from the manufacturers' published specifications, measurements taken by independent outlets that do have labs, and the structural reasoning on this site about what a given house or job actually needs. Every product was checked as currently sold before it was included. Where a figure appears it is attributed and linked in Sources; where we have no basis for a claim, it is left out. Our methodology sets out exactly what we will and will not assert.

goCoax MA2500DFull MoCA 2.5 in the 2.5 Gbps class at a fair price. If the coax answer is yes, this is the pair to start with — and it beats every wireless option in the same two rooms.
ScreenBeam ECB6200K02Bonded MoCA 2.0 tops out near 1 Gbps, which is everything you need below a gigabit plan, for less money than MoCA 2.5. The sensible pick if you are not paying for multi-gig.

Common questions
Are MoCA adapters worth it?+−
Yes, when both rooms have a coax outlet fed from the same splitter. In that case a pair gives you a shielded, gigabit-class wired link for far less than any rewiring, and it is the best possible backhaul for a mesh system in a house you cannot drill. Without coax in both rooms they are useless.
Is MoCA better than Ethernet?+−
No — a run of Ethernet cable is faster, cheaper and needs no power. MoCA is what you use when running that cable is impossible or unacceptable, which in rented and finished homes is most of the time. Think of it as Ethernet over wiring you already paid for.
Do I need a MoCA filter?+−
In almost all cases, yes. A point-of-entry filter costs a few dollars and fits where the coax enters the building. It keeps your MoCA signal inside the house rather than leaking onto the provider's line, which both improves your link and avoids annoying the neighbors on the same cable run.
Can MoCA work alongside cable internet on the same coax?+−
Yes. MoCA uses frequencies above the ones cable internet and cable TV use, so the two coexist on the same wiring. A point-of-entry filter is what keeps the arrangement clean, and it is the one accessory worth buying at the same time as the adapters.
