ScreenBeam Bonded MoCA 2.5 Network Adapter for Highest Speed Internet, Ethernet Over Coax - Starter Kit (Model: ECB7250K02)

Why we love it
  • Faster than typical Wi-Fi.
  • Ideal for gaming and streaming.
  • Easily uses existing coax cables.
Main Highlights
  • Faster than Wi-Fi: The ECB7250 uses your home's coax cables to deliver internet speeds up to 2.5 Gbps, surpassing Wi-Fi speeds. Actual speeds can be affected by various factors like cable quality and other MoCA devices on the network.
  • Get the Best Speeds and Bandwidth: The 2.5Gbps network ethernet port for high-speed internet is ideal for 4K streaming, gaming, and remote work. It's backwards compatible with 10/100/1000 Mbps Ethernet connections.
  • Skip the Wi-Fi! Use existing coax cables for wired Ethernet connections in your home. MoCA Adapter 2.5 delivers faster, more reliable speeds than Wi-Fi for up to 16 nodes on one network. You can also use these to connect remote Wi-Fi access points.
  • Check MoCA Compatibility: You will need 1 ECB or a MoCA compatible router or 2+ ECBs for non-MoCA routers. Most FiOS routers have MoCA built-in. Connect ECBs in each room with coax for wired access and switches to the ECBs for more ethernet connections.
  • 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 kit 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
  • What's Included? Everything you need to enhance your homes wired network using the coax cable already built into your home, includes 2 ECB7250 Adapters, 2 Power Adapters, 2 Ethernet Cables, 2 Coax Cables, 2 Coax Splitters and a quick start guide.

Why we love it
  • Faster speeds than typical Wi-Fi.
  • Ideal for gaming and streaming.
  • Utilizes existing home coax cables.
Main Highlights
  • Faster than Wi-Fi: Use your home’s coax cables for internet speeds up to 1 Gbps, perhaps outpacing Wi-Fi. With multiple adapters and a native MoCA router, MoCA speeds can reach 2.5 Gbps. Speed may vary due to cable quality and other MoCA devices.
  • Get Better Speeds and Bandwidth: The 1Gbps ethernet port and network card for high-speed internet is ideal for 4K streaming, gaming, and working from home. If your devices don't have a 1Gbps Network Card, it's backwards compatible with 10/100 Mbps network devices.
  • Skip the Wi-Fi! Use existing coax cables for wired Ethernet connections in your home. MoCA Adapter 2.5 delivers faster, more reliable speeds than Wi-Fi for up to 16 nodes on one network. You can also use these to connect remote Wi-Fi access points.

Why we love it
  • Transforms coax to fast Ethernet.
  • Enhances WiFi speed effortlessly.
  • Ideal for gaming and streaming.
Main Highlights
  • ⚠️ COMPATIBILITY CHECK REQUIRED BEFORE PURCHASE: Your home’s coax outlets MUST be connected through a central splitter/distribution panel for this to work. If coax outlets are isolated, disconnected, or used for satellite TV (DirecTV, Dish, AT&T U-verse), this product will NOT function. Test with a coax tester or contact your cable company to verify connectivity first.
  • 🏠 PERFECT FOR CABLE INTERNET HOMES: Works with cable internet providers (Comcast, Spectrum, Cox, etc.) where coax cables connect to a main splitter. Does NOT work with satellite internet, AT&T fiber, or homes with isolated coax outlets. Transforms connected coax TV outlets into 2.5 Gbps Ethernet ports.
  • 🚀 2.5 GBPS MAX ETHERNET SPEED: Delivers up to 2.5 Gigabit per second wired connection through your existing coax cables. Perfect for 4K streaming, gaming, and high-bandwidth devices. Actual speeds depend on your internet plan and network conditions.
  • **NETWORK EXTENDER (NOT A MODEM OR ROUTER)** - This is NOT a modem, router, or internet provider. It works alongside your existing equipment to extend internet through coax cables. Doesn't replace your internet equipment - enhances your current setup by bringing reliable, wired Ethernet connections to rooms without network wiring.
  • ✅ COMPATIBLE WITH ALL CABLE INTERNET: Works alongside your existing cable modem (this is NOT a replacement modem). Converts coax wall outlets to Ethernet connections. High-split cable internet requires additional POE filter at service entry point (sold separately).
  • BEST FOR: Cable or fiber internet homes with connected coax network. For best performance, pair with other HTEM5 adapters - mixing different MoCA versions may limit speeds. Will NOT work if coax outlets are isolated or used for satellite TV service. NOT COMPATIBLE with Direct TV, Dish, other satellite TV, AT&T Internet or AT&T U-verse coax networks. These services have frequency overlap and cannot be used on the same Coaxial network.
  • 📋 SMART PURCHASING GUIDE: This 2-pack includes 1 adapter for near your router + 1 for your device location. Each coax outlet needs its own adapter. Count your needed locations first - buy additional single units if you need more than 2 connections.
  • 📦 COMPLETE 2-PACK KIT: Includes 2x MoCA 2.5 adapters, 2x Ethernet cables, 2x power adapters, and setup guide. POE filter for high-split DOCSIS systems sold separately if needed. Easy plug-and-play installation.
  • 🔧 PRE-PURCHASE VERIFICATION STEPS: 1) Locate your home’s main coax splitter 2) Verify all outlets connect to this splitter 3) Ensure you have cable internet (not satellite) 4) Check that coax isn’t exclusively used for satellite TV. Following these steps prevents 90% of connectivity issues.
  • 📞 SETUP SUPPORT INCLUDED: Free technical support available if you experience connectivity issues. Most problems stem from home wiring configuration, not product defects. Our support team can help verify your coax network compatibility and optimize performance.

Why we love it
  • Extremely high bandwidth capabilities.
  • Minimized external interference ensured.
  • Lower latency enhances gaming experience.
Main Highlights
  • MoCA 2.5 can offer extremely high bandwidth of 2.5 Gbps. This bandwidth are shared by all the MoCA devices in the same coaxial network. That’s more than enough to allow streaming 4K/8K videos at the same time, while still playing an online game and transferring pictures from a computer or a mobile device to a television for viewing.
  • Combined with the 2.5GbE Ethernet inerface, our product can provide the real 2.5Gbps backhual to your home network. This is a cost effective and amazing upgrading.
  • Unlike Wi-Fi, MoCA is based on coaxial cable, a shielded metal wire. That can minimize the external interference. Also the attenuation of the cable is very small, less than 8dB per 100 feet. Even with a 60dB path loss, you still can get a full-speed connection. It is almost comparable to Ethernet.
  • Improve online gaming by lower latency. Latency is the important quality of your network, it is the term used to indicate any kind of delay that happens in data communication over a network. When play games online, latency is critical. The lower latency, the better gaming experience. MoCA 2.5 can achieve 3ms delay. For Wi-Fi, the value is variable, from milliseconds to tens of milliseconds. So MoCA is the best choice for gaming players.
  • Please buy at least two devices to enjoy the high speed MoCA 2.5. They can be connected to a variety of devices in the home. Maximum 16 MoCA devices in every home network.
