ScreenBeam ECB7250S02 Network Adapter Add-On Only Bonded MoCA 2.5

Bottom line: The ScreenBeam ECB7250S02 Network Adapter Add-On Only Bonded MoCA 2.5: 2.5 Gbps Ethernet port, well above MoCA 2.0 add-on adapters; main trade-off: add-on only: useless without an existing MoCA 2.5 adapter or router.

Pros & Cons

Pros

  • ✓ 2.5 Gbps Ethernet port, well above MoCA 2.0 add-on adapters
  • ✓ Uses existing in-wall coax, so no new Ethernet runs needed
  • ✓ Scales to 16 nodes on a single MoCA network
  • ✓ Backward compatible with 10/100/1000 Mbps devices
  • ✓ Ships with 2 Ethernet cables, coax cable, and a coax splitter

Cons

  • ✗ Add-on only: useless without an existing MoCA 2.5 adapter or router
  • ✗ Not compatible with DirecTV, Dish, AT&T internet, or U-verse coax
  • ✗ Some DOCSIS 3.1 modems overlap frequencies and cause random drops
  • ✗ Comcast gateways cap at MoCA 2.0; you must disable gateway MoCA

Manufacturer description

The ScreenBeam ECB7250S02 is a single add-on adapter for an existing MoCA network, turning the coax already running through your walls into a wired 2.5 Gbps Ethernet link. It is the add-on unit only, so you need at least one other MoCA 2.5 adapter or a MoCA-capable router (most FiOS routers qualify) already in place. Once paired, it delivers the low latency and consistency that Wi-Fi struggles with in rooms far from the router, which matters for competitive gaming, 4K streaming, and large file transfers. The 2.5 Gbps Ethernet port hits full speed only with 2.5 Gbps-capable gear, and stays…

SpecPicks Verdict

SpecPicks scored ScreenBeam ECB7250S02 Network Adapter Add-On Only Bonded MoCA 2.5 using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. ScreenBeam's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

Does this come with a second adapter?

No. The ECB7250S02 is a single add-on unit for an existing MoCA network. You need a MoCA-capable router or another MoCA adapter already installed for it to pair with.

Will it work with my Comcast Xfinity setup?

Partially. Comcast only supports MoCA 2.0 with the Xfinity XB8 gateway. To get full MoCA 2.5 speed from the ECB7250, turn MoCA off in your Comcast gateway and let the ScreenBeam adapters run the network.

How many adapters can I put on one network?

Up to 16 nodes on a single MoCA network. Each device you want wired needs its own adapter, and each room needs a coax jack to connect to.

Will I actually get 2.5 Gbps?

Only if the devices on both ends have 2.5 Gbps Ethernet ports. Otherwise it falls back to 10/100/1000 Mbps. Real speeds also vary with network traffic, wiring materials, and how many devices are connected.

Is it compatible with satellite TV or AT&T service?

No. ScreenBeam lists DirecTV, Dish and other satellite TV, AT&T internet, and AT&T U-verse coax networks as incompatible. Some DOCSIS 3.1 modems can also conflict on frequency and cause disconnects; ask your ISP about a fix.

Key Features

  • Boost Your MoCA Network with this add-on for a 2.5 Gbps ethernet-coax connection, outdoing traditional Wi-Fi speeds. Speeds vary due to network traffic, materials, and connected devices. Check compatibility with MoCA 2.5 adapter for optimal performance.
  • Enhance Gaming and Streaming with our Carrier-Grade ECB7250 featuring a 2.5Gbps network ethernet port for top 4K/HD performance. Full speed requires compatible 2.5Gbps devices; otherwise, it’s backward compatible with 10/100/1000 Mbps devices.
  • Add on to Your Starter Kit for a robust Ethernet network with MoCA Adapter 2.5, outperforming wireless for speed, latency, and security between router and any device with an Ethernet port. Supports up to 16 nodes on one network.
  • Router Requirements: Built-in or added MoCA capability for network connections. Most FiOS routers have MoCA built-in. Each network device (up to 16) needs a MoCA Adapter. Rooms with coax jacks need an ECB for Ethernet. Check coax MoCA compatibility.
  • Device Compatibility: This MoCA adapter for ethernet over coax works with most devices and routers with an ethernet port. However, some DOCSIS 3.1 modems might conflict (frequency overlap) and cause random disconnects. Check with your ISP for a fix.
  • Non-Compatibility: This MoCA ethernet to coax adapter is not compatible with Direct TV, Dish or other satellite TV, AT&T internet, or AT&T U-verse coax networks. Comcast only supports MoCA 2.0 with Xfinity XB8. Turn off MoCA in your Comcast gateway to take full advantage of MoCA 2.5 in ECB6250 and ECB7250 Adapters
