One Coax Outlet. Two Full-Speed Connections.
KB-M3-02 — the only MoCA 2.5 adapter in the world with two 2.5 Gigabit Ethernet ports.
Tired of Wi-Fi dead zones, buffering, and dropped calls? Turn the coax already in your walls into a rock-solid 2.5 Gbps wired backbone — no new cabling, no drilling, no compromise.
Two ports. One coax cable. Zero rewiring.
Here's how it works: the coax already running through your walls becomes a high-speed data line the moment you plug in the KB-M3-02. No electrician, no new cable runs, no drilling through walls or floors — just connect the coax jack and you're done. The dual ports mean that one outlet, in one room, can now serve two devices at full speed instead of one.
Why People Choose the KB-M3-02
Streamlined endpoint setup
Simplify your installation. The KB-M3-02 acts as a high-performance bridge that eliminates the need for an additional network switch at your destination point, reducing power clutter and saving valuable outlet space.
Real, tested throughput
iperf-verified 2.5 Gbps performance — not theoretical numbers. Built on the MaxLinear MxL3710 + GPY211 PHY.
Low latency for gaming
Adds just 3–4 ms — dramatically more stable than Wi-Fi for competitive play and video calls.
Mesh backhaul ready
Give Eero, Orbi, Ubiquiti or any mesh a wired backbone for faster, more reliable whole-home coverage.
Truly plug & play
Connect coax and Ethernet — that's it. No software, no configuration for most setups.
Backward compatible
Works alongside MoCA 1.1 / 2.0 / 2.5 gear from GoCoax, Actiontec, ScreenBeam and more.
Typical setup: router on one port, a games console or NAS on the other — both running at full 2.5 Gbps from the same wall jack.
Why two ports change everything
KB-M3-02 vs a standard MoCA 2.5 adapter with one 2.5GbE port
| Standard MoCA 2.5 1 × 2.5GbE port |
KB-M3-02 — Kiwee ★★★★★ 2 × 2.5GbE ports |
|
|---|---|---|
| Ethernet ports | 1 × 2.5GbE | ✓ 2 × 2.5GbE — world’s only |
| Devices per coax outlet | 1 device | ✓ 2 devices simultaneously |
| External switch required? | ✗ Yes — extra cost & clutter | ✓ No — built-in dual port |
| TV coax passthrough port | ✗ Not included | ✓ Yes — dedicated TV port (5–1002 MHz) |
| Keep cable TV on same coax line | ✗ Requires external diplexer | ✓ Built-in diplexer — no extra hardware |
| Mesh backhaul + wired device | Needs a second coax outlet | ✓ Both from one wall jack |
| Gaming + streaming simultaneously | Not possible on one port | ✓ Full 2.5 Gbps on each port |
| Verified throughput | Spec-sheet only | ✓ iperf-tested & published |
| Chipset | Varies by brand | ✓ MaxLinear MxL3710 + GPY211 |
| Gaming latency added | Similar | ✓ Only 3–4 ms measured |
| FCC / CE / UL certified | Varies | ✓ Yes — all three |
Is the KB-M3-02 right for you?
10-second check — pick your situation below.
✅ Perfect fit — get it
- You have coax outlets in the rooms you want to connect
- You want wired Ethernet without running new cables — even for just one device today
- You might add a second device later (NAS, console, mesh node, smart TV) — the second 2.5GbE port is already there, no extra hardware needed
- You want to keep cable TV working on the same coax line
- High-demand use: gaming, 4K streaming, NAS, mesh backhaul
⚠️ Check first
- No coax outlets in your home — MoCA requires coax
- Satellite TV (Dish, DirecTV) — use the KB-M3-02E (E-Band) instead, which is designed for satellite coax
- Your ISP actively blocks MoCA on their coax network — verify with them first
Built for the way modern homes use bandwidth
Wherever Wi-Fi falls short, the KB-M3-02 gives you a wired-quality connection without running a single new cable.
Common questions before you buy
"Will it actually work with my setup?"
If your home already has coax outlets (from cable TV or older internet wiring), this plugs straight in. No new cabling needed.
"Is setup complicated?"
For most homes, no — connect coax and Ethernet and it's online. Advanced settings exist for edge cases (see the setup guides below) but aren't required for typical use.
"What if I'm not happy with it?"
30-day returns through Amazon, plus a 1-year warranty if anything goes wrong after that.

Step-by-step guides for every configuration — most users are live in under 5 minutes.
Configure D-Band High to eliminate DOCSIS 3.1 interference
Shift to D-Band High (1350–1675 MHz) and apply a 1400 MHz LOF on every adapter for a rock-solid, interference-free MoCA link.
Check firmware & link rate for stable performance
Verify your firmware version and MoCA link rate. A healthy link rate is ~3500 Mbps — this guide shows you how to confirm everything is optimal.
Switch from static IP to DHCP for automated management
Enable DHCP so the adapter pulls its management IP automatically — easier to manage across multiple adapters and network changes.
Enable MoCA traffic security across your network
Enable D-Ext encryption and use MPS pairing to protect data on your MoCA network from unauthorized access across all adapters.
