Two 2.5G Ports. One Coax Cable. Zero New Wiring.
Your walls already contain a multi-gigabit network — the coax cable behind your TV. The Kiwee KB-M3-02 (D Band) and KB-M3-02E (E Band, for satellite-TV homes) turn it into wired Ethernet for two devices at once: no drilling, no switch, no Wi-Fi lottery.

Wi-Fi wasn’t built for what you’re asking it to do
🎮 Gamers
A ping spike in the final circle. Packet loss in overtime. Wi-Fi fails at exactly the moments that matter, and no router upgrade fully fixes physics.
📺 4K/8K streamers
The movie looks perfect — until the household gets home and every phone, laptop and console starts competing for the same crowded airwaves.
💼 Remote workers
The presentation that freezes mid-sentence. The upload that crawls. When your income depends on your connection, “usually fine” isn’t fine.
Ethernet fixes all of this — but running new cable through finished walls costs hundreds of dollars and days of mess. There’s a third option, already installed in your home.
The network hiding in your walls
Connect at the router
Screw one adapter onto the coax jack near your router and link them with an Ethernet cable.
Connect in any room
Screw a second adapter onto any other coax jack in the house — bedroom, office, den.
Plug in and play
Plug your devices into the Ethernet ports. Full-speed wired network — and your TV signal keeps working through the built-in pass-through port.
MoCA 2.5 runs at 1150–1650 MHz — above the frequencies your TV and cable modem use — so everything coexists on the same cable.
Why two ports change the math
Two devices, no switch
Feeding a PC and a console from a single-port adapter means buying a 2.5G switch — another $30–60, another power brick, another box on the shelf. The KB-M3-02 is the only MoCA adapter that makes the switch unnecessary.
Full backhaul utilization
The MoCA 2.5 link carries roughly 3 Gbps in total. One 2.5G port can never saturate it. Two ports share it — your NAS backup runs at full speed while you game, with no bottleneck.
The router-room problem, solved
At the point where internet enters your home: one port to your router, one to a mesh node or desktop. One box now does what used to take two.
Room to grow
Multi-gig internet plans, 8K streams, a home server — when the second device arrives in that room, the port is already there waiting.
MoCA 2.5 vs. the alternatives
| Kiwee dual-port MoCA | Wi-Fi mesh | Powerline | New Ethernet runs | |
|---|---|---|---|---|
| Real-world speed | 2.5 Gbps, consistent | Varies with walls & congestion | Depends on electrical wiring | Up to 10 Gbps |
| Latency & stability | Wired-grade, +3–4 ms | Fluctuates under load | Inconsistent | Best possible |
| Installation | Screw onto existing coax | Easy | Easy | Invasive & costly |
| Uses existing wiring | Yes — your coax | — | Yes, electrical | No — new cable |
| Devices per adapter | 2 (dual port — unique) | — | Usually 1 | 1 per run |
| Cost of a 2-device room | One adapter | Extra node | Adapter + switch | Two runs or a switch |
Which Kiwee adapter is right for your home?
Quick guide: Cable internet or antenna TV → D Band (KB-M3-02). Satellite TV in the house → E Band (KB-M3-02E). Powering a Wi-Fi access point or camera → PoE+ (KB-M3-03).
Both dual-port models share the exact same design — the operating band is the only difference. Pick by your TV service, everything else in this guide applies to both.

Dual 2.5GbE · D Band
- 2 × 2.5G Ethernet ports
- D Band (1150–1650 MHz)
- Works with cable internet (DOCSIS) & CATV
- TV pass-through port
- Best for: multi-device rooms, mesh backhaul
KB-M3-02E
Dual 2.5GbE · E Band Extended
- 2 × 2.5G Ethernet ports
- E Band (400–900 MHz)
- Made for homes with satellite TV
- TV pass-through port
- Best for: satellite households, multi-device LAN
KB-M3-03
1 × 2.5GbE · PoE+
- 1 × 2.5G Ethernet port with PoE+
- D Band (1150–1650 MHz)
- Powers APs & cameras over the cable
- Works with cable internet (DOCSIS) & CATV
- Best for: Wi-Fi access points, PoE devices

Read all customer reviews →Frequently asked questions
Do both ports really run at 2.5 Gbps at the same time?
Yes. Both ports can run at 2.5 Gbps simultaneously, sharing the total MoCA 2.5 bandwidth of approximately 3 Gbps — ideal for a router plus a high-speed device, or two separate network segments.
What’s the difference between the KB-M3-02 and KB-M3-02E?
Same dual-port design, different operating band. The KB-M3-02 uses D Band (1150–1650 MHz) for homes with cable internet or antenna TV. The KB-M3-02E uses E Band Extended (400–900 MHz) for homes with satellite TV, whose signals occupy the D Band frequencies. They are not interchangeable — pick by your TV service.
Will it work with my DOCSIS 3.1 cable modem?
Yes. Some DOCSIS 3.1 modems require a one-time setting: in the adapter’s interface, select “D-band High only” mode and set the LOF to 1400 MHz to avoid interference with DOCSIS 3.1 frequencies. A step-by-step video guide is on the product page.
Does it work as wired backhaul for Eero, Orbi or Ubiquiti mesh?
Yes. It’s ideal for mesh backhaul, giving your nodes a stable wired link that outperforms wireless backhaul. Compatible with Ubiquiti, Eero, Orbi and other mesh systems.
Can I mix it with goCoax, ScreenBeam or Actiontec adapters?
Yes. It’s backward compatible with MoCA 1.1, 2.0 and 2.5 and works alongside other brands. Network speed follows the slowest adapter connected.
How hard is installation?
Screw the adapter onto a coax jack, plug in Ethernet, done. The built-in pass-through port keeps your TV signal working on the same cable. No drivers, no software.
How much latency does it add for gaming?
Only 3–4 milliseconds — excellent for competitive gaming and real-time applications, and significantly lower than Wi-Fi alternatives.
Your coax is already installed. Use it.
Multi-gigabit wired networking for two devices per room, with the cable that’s been in your walls all along. Set up in minutes, built to last.
