Your office is two floors from the router, and the cable that can fix that is already in the wall: the coax behind the TV plate. The best MoCA adapter turns that coax into a wired Ethernet backbone without pulling a single new cable, and in most houses it beats both a mesh hop and a powerline kit on speed. The catch is that a pair of MoCA 2.5 adapters only pays off if the Ethernet port on each box is faster than gigabit, which rules out a surprising number of best sellers.
We compared the goCoax MA2500D, the ScreenBeam ECB7250 and ECB6250, the Hitron HTEM5 and the TRENDnet TMO-312C2K against a TP-Link AV2000 powerline kit, on port speed, frequency band, encryption, warranty and what the box leaves out. Every spec sheet, Amazon listing and price below was checked in October 2026, and none of these adapters went through our lab, so each throughput figure you see names its source. The PoE filter and splitter rules that decide whether MoCA works at all are covered too.
The short list
Every pick below except the powerline kit is a MoCA 2.5 adapter, so the differences come down to the Ethernet port, the vendor’s documentation and how easily the kit grows past two rooms:
- Best overall, Hitron HTEM5: a 2.5GbE port, AES-128 listed on the spec table, and every cable and power supply in the box. About $120 for a pair on Amazon, check the live price.
- Best for homelab tinkering, goCoax MA2500D: a 2.5GbE port plus a web UI that lets you move the adapter between the full D band and its low or high half. Sold direct by goCoax.
- Best for adding rooms later, ScreenBeam ECB7250: the 2.5GbE ScreenBeam model, with a single add-on unit sold on its own. About $150 for the starter pair, check the live price.
- Best warranty, TRENDnet TMO-312C2K: a gigabit port, but three years of cover and a spec page that names Verizon Fios and Spectrum as compatible. About $120 for a pair, check the live price.
- No coax at all, TP-Link TL-PA9020P KIT: AV2000 powerline with two gigabit ports per adapter and a passthrough socket. About $80 for the kit, check the live price.
Add a MoCA point-of-entry filter to any of the coax kits if your house has a cable internet or cable TV feed. It costs about $8 and the section on your coax explains where it goes.
How we picked these adapters
Our method here is a spec and listing comparison, not a bench test. We had none of these adapters on hand. So instead of inventing numbers, we read each maker’s product page or spec table and checked the exact Amazon listing for the kit (two-pack versus single add-on, gigabit versus 2.5GbE port). Then we looked for an independent throughput figure. Where no clean independent measurement exists, we say so rather than quote a forum anecdote as fact.
Four filters decided the ranking, in this order:
- Ethernet port speed: MoCA 2.5 is specified for up to 2.5 Gbps of actual data rate, so a gigabit port throws away more than half of it.
- Documentation: a published spec table with the frequency range, encryption and package contents beats a marketing page that only says “fast”.
- Expansion path: a single add-on unit you can buy later costs far less than a second starter kit.
- Availability: a kit that ships in two weeks from a third-party seller is not a recommendation, however good the hardware.
The Motorola MoCA 2.5 single unit failed that last test. On our check date its Amazon listing had no buy box and quoted a 10 to 11 day lead time from a third-party seller, so it sits in the skip list near the end instead of in the picks.
MoCA 2.5 adapters compared
Read the Ethernet port column first, because it caps everything else. The gigabit row cannot move more than 1 Gbps between rooms however clean your coax is. The three 2.5GbE rows can use what MoCA 2.5 offers, as long as the device on the far end has a 2.5GbE port too.
| Kit | Ethernet port | Coax band | Encryption listed | Warranty | Price band (pair) |
|---|---|---|---|---|---|
| Hitron HTEM5 | 2.5GbE | 1125 to 1675 MHz | AES-128, DES-56 | 1 year | about $120 |
| goCoax MA2500D | 2.5GbE | 1125 to 1675 MHz | not stated | not stated | about $120 |
| ScreenBeam ECB7250K02 | 2.5GbE | MoCA 2.5 | not stated on page | not stated on page | about $150 |
| TRENDnet TMO-312C2K | 1GbE | 1125 to 1675 MHz | not stated | 3 years | about $120 |
| TP-Link TL-PA9020P KIT | 2x 1GbE each | mains wiring | AES-128 | not stated | about $80 |
“Not stated” means the maker page we fetched did not list it, not that the feature is missing. ScreenBeam’s product pages render their spec tables with JavaScript and we could only confirm the port speed from them, which is why its row is thinner than the others. Prices are Amazon US figures on our check date. The goCoax figure is the Amazon two-pack price we saw on the listing page. That listing is not in the affiliate catalogue we use, so we link goCoax’s own store, which sells single units.
Hitron HTEM5, the best MoCA adapter for most homes
The HTEM5 wins because Hitron publishes more about it than anyone else does about their adapter, and everything it publishes is what you want. Each unit has one 2.5GbE port and one coax input, runs MoCA 2.5 across five bonded channels for up to 2.5 Gbps between adapters, and stays inside the 1125 to 1675 MHz band. The spec table lists both 56-bit DES and 128-bit AES for link privacy.
The box holds two adapters, two Ethernet cables, two coax cables and two power supplies, so the only thing you may still need is a MoCA-rated splitter, which Hitron sells separately. Each unit measures 70 x 110 x 25 mm, small enough to sit behind a TV stand next to the wall plate. Hitron also documents backward compatibility with bonded MoCA 2.0, MoCA 2.0, 1.1 and 1.0, which matters if your cable box already speaks an older MoCA version on the same wiring.
- Who it’s for: anyone with cable TV coax in the rooms they need to connect and a 2.5GbE switch, NAS or access point on the far side.
- Skip it if: you want a long warranty, since Hitron covers it for one year, or you watch satellite TV, because Hitron lists it for cable TV homes only.
- Price: about $120 for the pair on Amazon; check the live price before you order.
goCoax MA2500D, the homelab favourite with a web UI
goCoax is the name that comes up first in homelab threads. The MA2500D earns it with one feature the others do not advertise: a web interface that switches the adapter from the default Extended D band (1125 to 1675 MHz) to D Low or D High. goCoax only says that in some special cases you have to force the adapter to D Low. Our reading: it covers wiring where another MoCA network already sits in part of the band. Moving your pair to the other half then fixes it with no new hardware.
Beyond that, the spec matches the HTEM5: one 2.5GbE port, MoCA 2.5 with up to five bonded channels, up to 16 nodes, and an MPS button for push-button pairing. Each unit runs from a 12 V, 0.5 A supply. goCoax is unusually frank about two failure cases on its product page. It does not work in DirecTV or satellite homes. And some DOCSIS 3.1 cable modems use frequencies above 1002 MHz (goCoax cites 1218 MHz), so it tells you to feed the adapter from a 2-way splitter and put a PoE filter just before the cable modem. There is no filter in the box.
We could not find a clean independent measurement of the MA2500D at multi-gig speeds. The best sourced figure is from an SNBForums thread, where a pair of goCoax’s earlier gigabit-port adapters measured 935 Mbps in iperf3, which is what a saturated gigabit port looks like. Treat it as proof that the gigabit models hit their port limit, not as an MA2500D result.
- Who it’s for: homelab owners who want to see the link, change the band and live with a smaller vendor.
- Skip it if: you want encryption and warranty terms in writing before you buy, since the product page we read listed neither, or you shop only through Amazon’s own catalogue.
- Where to buy: direct from gocoax.com, which sells single units. A two-pack listed at about $120 on the Amazon page on our check date.
ScreenBeam ECB7250, the easiest kit to grow
ScreenBeam sells two MoCA 2.5 kits that look almost identical, and the model number is the whole story. The ECB7250 has a 2.5GbE Ethernet port; the ECB6250 has a gigabit one. Both starter kits list at about $150 on Amazon, so there is no reason to pick the ECB6250 for a new build. What makes the ECB7250 the pick for a growing network is the single add-on unit, the ECB7250S02, which listed at about $90 on our check date.
Every adapter you add joins the same MoCA network, so a three-room setup is a starter pair plus one add-on rather than two starter kits. In practice that saves about $60 on a third room, and buying all units from one vendor also follows the advice Dong Ngo gives in his MoCA explainer: adapters from different vendors are supposed to work together, but a mixed pair might work or might not. ScreenBeam says plainly that its MoCA adapters don’t work in satellite TV homes, because satellite uses the same frequencies.
- Who it’s for: houses where you’ll wire a second or third room later and want one family of adapters.
- Skip it if: you only need two rooms, because the Hitron pair costs about $30 less for the same port speed, or you need a published spec table before you buy.
- Price: about $150 for the ECB7250K02 starter kit and about $90 for the ECB7250S02 add-on; check live prices.
TRENDnet TMO-312C2K, gigabit with a three-year warranty
TRENDnet’s kit is the one gigabit pick on the list, and it is here for its paperwork rather than its speed. TRENDnet covers the TMO-312C2K for three years, three times Hitron’s term. Its product page is also the most specific of any vendor about which providers work: Verizon Fios and Spectrum are listed as compatible, while DirecTV, Dish, other satellite services and AT&T U-verse are not. The adapter defaults to the 1150 MHz channel and draws 12 W at most from a 12 V, 1 A supply.
The trade-off is blunt. At about $120 it costs the same as the Hitron pair, which has a 2.5GbE port, so you’re paying for warranty and documented provider support with half the potential speed. That’s a fair deal when everything downstream is gigabit anyway: an older router, a gigabit switch, a mesh node with a 1GbE backhaul port. TRENDnet also sells a 2.5GbE version, the TMO-313C2K, at about $140, but it had only 22 Amazon reviews on our check date and we could not read its full spec sheet, so it is not a pick yet.
- Who it’s for: Fios and Spectrum homes with gigabit gear that want the longest cover on this list.
- Skip it if: your internet plan or your NAS is faster than 1 Gbps, because the port caps the link at gigabit.
- Price: about $120 for the two-pack; check the live price.
TP-Link AV2000 powerline, the fallback when there is no coax
Powerline sends Ethernet over your mains wiring, so it works in rooms that never had a coax outlet. The TL-PA9020P KIT is the version we would buy. It runs HomePlug AV2 with 2×2 MIMO and puts two gigabit ports on each adapter, plus AES-128 and a passthrough socket with a noise filter so you do not lose the outlet. Maximum draw is 5.8 W. It is also the cheapest kit here at about $80 for two adapters.
Do not read “2000” as a speed. TP-Link’s own footnote calls it the theoretical physical rate, and the real numbers are a fraction of it. Tech Advisor’s 2017 review of TP-Link’s AV2000 kits measured 432 Mbps with both adapters in the same room and 117 Mbps with them two floors and about 30 m apart. The review covers both the TL-PA9020 KIT and this passthrough version and does not say which pair was speed-tested. The second figure is the one that matches a real living-room-to-office run, and it is about an eighth of what a gigabit MoCA pair delivers.
- Who it’s for: rooms with no coax outlet, or a satellite home where MoCA is off the table.
- Skip it if: you have usable coax in both rooms, because even the same-room figure above sits well under a gigabit MoCA pair.
- Price: about $80 for the kit; check the live price.
MoCA vs powerline in practice
If you have coax in both rooms, MoCA wins on every axis that matters for a backbone link. Coax is a shielded cable built to carry RF, while mains wiring was built to carry power and picks up noise from every motor and charger on the circuit. Dong Ngo’s MoCA explainer describes powerline as half-duplex and closer to Fast Ethernet in practice, while MoCA can sustain real gigabit or multi-gig. The table puts the published figures side by side:
| MoCA 2.5 (2.5GbE kit) | AV2000 powerline | |
|---|---|---|
| Medium | Existing coax | Mains wiring |
| Rated rate | Up to 2.5 Gbps actual data rate (MoCA Alliance) | 2000 Mbps PHY, theoretical (TP-Link) |
| Measured, independent | 935 Mbps iperf3 on a gigabit-port pair (SNBForums) | 432 Mbps same room, 117 Mbps two floors apart (Tech Advisor) |
| Breaks when | Satellite TV shares the coax, or an old splitter blocks 1125 to 1675 MHz | Outlets sit on different circuits or behind surge strips |
| Pair price | about $120 to $150 | about $80 |
The MoCA measured row is a gigabit-port result because that is the cleanest independent figure we could source; it shows the gigabit adapters running at their port limit, and a 2.5GbE pair has headroom above it. The MoCA Alliance’s MoCA 2.5 announcement gives the rated figures: up to 2.5 Gbps of actual data rate, up to 16 nodes, and backward interoperability with MoCA 2.0 and 1.1.
What your coax needs before MoCA works
Most MoCA failures are wiring failures, not adapter failures. One adapter plugs into a coax outlet near your router and connects to a LAN port; the other plugs into the coax outlet in the far room and feeds a switch or access point. Between them, the signal has to pass every splitter on the path, and it should not leak out to the street.
The diagram shows the layout every vendor in this guide describes, and four parts of it decide whether the link comes up:
- Point-of-entry filter: fit a MoCA PoE filter where the cable drop enters the house. Hitron explains that it keeps your MoCA traffic in and your neighbours’ out. The PPC MoCA POE filter listed at about $8; a sibling PPC model in the same family is specified for 5 to 1002 MHz, so check the passband against your modem’s upper frequency.
- Splitters rated for MoCA: every splitter between the two adapters must pass 1125 to 1675 MHz. Dong Ngo’s advice is a splitter rated above 1000 MHz at minimum and ideally above 1500 MHz, because a lower-rated one might work but often doesn’t.
- No amplifiers in the path: Dong Ngo recommends keeping amplified splitters out of the MoCA path and using at most one layer of splitters behind the main one.
- No satellite on the same coax: goCoax, TRENDnet and ScreenBeam all say MoCA is not compatible with DirecTV or other satellite TV, because they use overlapping frequencies.
People skip the PoE filter and then regret it. Without one, your MoCA network can reach the provider’s tap outside, so a neighbour’s adapters may see yours. On a DOCSIS 3.1 service using the 1218 MHz extended range, the modem and the MoCA band can also step on each other. goCoax handles that case with a different placement: a 2-way splitter, with the PoE filter just before the cable modem on one leg and the MoCA adapter on the other. A filter that only passes up to 1002 MHz suits older DOCSIS 3.0 plans. Fitted at the entry, it would also cut the upper spectrum an extended-spectrum DOCSIS 3.1 modem uses. Read the modem’s spec before you choose where the filter goes.
Some providers already run MoCA on your coax: Verizon’s own MoCA Ethernet adapter for Fios is rated for the same 1125 to 1675 MHz band. Two MoCA networks on one coax tree have to share that band. TRENDnet documents a default channel of 1150 MHz and says its kit needs no configuration, but not that the channel can be changed. goCoax lets you move between D Low and D High. If a new pair won’t link in a home where provider gear already uses MoCA, a band change on the goCoax is the first thing to try; on a kit with no band control, ask the vendor before you rewire.
MoCA kits we would skip
Three popular listings fail the port-speed or availability test, and they’re worth naming because they rank well on Amazon:
- ScreenBeam ECB6250K02: MoCA 2.5 radio with a gigabit port at the same price as the 2.5GbE ECB7250K02. Dong Ngo’s guide says it sustains gigabit at best.
- Hitron HTEM4 two-pack: about $15 cheaper than the HTEM5, but with a gigabit port, so you give up the upgrade path for very little saving.
- Motorola MoCA 2.5 single: no buy box and a 10 to 11 day lead time from a third-party seller on our check date.
A gigabit MoCA kit still makes sense in one case: when the TRENDnet warranty or provider list is the deciding factor and nothing on your network is faster than 1 Gbps. Otherwise, pay the same money for a 2.5GbE port and let the coax link keep up with your next switch.
Where MoCA fits in the rest of the network
A MoCA pair is a backbone link, so the device on each end decides what you actually get from it. We’d plan the far end before buying the adapters:
- Access point in the far room: MoCA makes a better backhaul than a wireless mesh hop. Pair a 2.5GbE kit with one of the Wi-Fi 7 access points that have a 2.5GbE uplink.
- Switch for a desk or rack: a gigabit kit feeds one of the cheap VLAN-capable gigabit switches; a 2.5GbE kit deserves a 2.5GbE or 10GbE managed switch.
- Router at the near end: check that the router’s LAN port matches the adapter. A gigabit LAN port on a Wi-Fi 7 router is the usual bottleneck people forget.
- Rentals and temporary setups: a rental with coax in every room takes a MoCA pair without touching the walls, and a travel router running WireGuard or Tailscale on the far end gives that room its own VPN-routed segment.
MoCA is the no-new-cable option, and it has a ceiling: 2.5 Gbps shared across up to 16 nodes on one coax tree. If you own the house and can open walls, pulling Cat6 gets you a dedicated link per room, and the guide to wiring a house for Ethernet covers that job. For everyone renting, or anyone who doesn’t want to fish cable through finished walls, a 2.5GbE MoCA pair and a filter matched to your modem is the cheapest real wired link you can buy.
