  • TypeAC Adapter
  • ColorBlack
  • Up to 2.5 Gbps networking over existing coaxial cables
  • Button-enabled MPS security simplifies network protection
  • Band mode switch avoids DOCSIS 3.1 interference for stable links
  • Ethernet-like latency supports responsive gaming sessions
  • 69% post-consumer recycled plastic housing with FSC-certified packaging

Single-Adapter Coax Networking

The ASUS MA-25 (1-PK) is a single-unit MoCA 2.5 adapter that turns existing coaxial cabling into a 2.5 Gbps Ethernet link. It targets homeowners who want wired-grade throughput for gaming, streaming or mesh backhaul without pulling new cables.

Coax Infrastructure Constraints

Performance depends on the quality and length of the installed coaxial plant, which the adapter cannot improve. The built-in band-mode switch mitigates interference from DOCSIS 3.1 cable modems, but splitters, amplifiers or degraded shielding still limit real-world throughput.

Single-Pack Purchase Constraint

The package contains only one adapter; a second MoCA 2.5 endpoint is required at the far end to complete the link. Buyers needing an immediate pair must source another unit separately.

Questions about this item

Should I buy a single MA-25 or do I need two units?

One adapter connects a single coaxial outlet to Ethernet; you need a second MoCA 2.5 device at the other end to complete the link.

What does the 2.5 Gbps figure mean once the adapter is installed?

It is the maximum MoCA 2.5 throughput over your existing coaxial wiring; actual speed depends on cable quality, splitters and ISP plan.

How does the band mode switch help with DOCSIS 3.1 modems?

It moves the MoCA channel away from DOCSIS 3.1 frequencies to reduce interference and keep the link stable.
