Review: It works and setup was simple - It works and setup was simple! I needed another Ethernet circuit in my home network, but I already had unused coax cables in the right place. Using these adapters, I didn't have to crawl around in the attic running new Cat 6 cables. New cables would have been cheaper (DIY), but saving the work, the time, and the hassle made these adapters worth the money for me. If you have a similar situation, I highly recommend these adapters. Review: Great Product - It was an easy installation. I’m working on a homelab server project, so I’ve learned a lot from setting this up, and it works great. I’m getting 900+ Mbps download and 900+ Mbps upload with no issues. The only challenge was that my home’s coaxial lines weren’t MoCA-ready, but I worked around it by using a switch, and everything runs perfectly now. Overall, it’s a great product and very affordable. ## Features - DEVICE INTERFACE: 1 x MoCA Coax: F-Type Female coax input, 1 x TV Coax: F-Type Female coax output, 1 x RJ-45 Gigabit LAN port.

I needed another Ethernet circuit in my home network, but I already had unused coax cables in the right place. Using these adapters, I didn't have to crawl around in the attic running new Cat 6 cables. New cables would have been cheaper (DIY), but saving the work, the time, and the hassle made these adapters worth the money for me. If you have a similar situation, I highly recommend these adapters. ### ⭐⭐⭐⭐⭐ Great Product *by A***M on December 3, 2025* It was an easy installation. I’m working on a homelab server project, so I’ve learned a lot from setting this up, and it works great. I’m getting 900+ Mbps download and 900+ Mbps upload with no issues. The only challenge was that my home’s coaxial lines weren’t MoCA-ready, but I worked around it by using a switch, and everything runs perfectly now. Overall, it’s a great product and very affordable. ### ⭐⭐⭐⭐⭐ First time MoCA user - fast connection *by J***Z on January 19, 2021* First time MoCA user, fast connection I’m a first time MoCA network user, but complete believer. If you understand that a wired connection is always an upgrade in bandwidth compared to using something like and extender, then this is for you. Just make sure you connect and set up correctly and you’re good to go. Setting up a MoCA network with my home Coax wires For those wondering if you’re MoCA compliant, or if you’re home has a MoCA compliant network, the adapters themselves are MoCA compliant. They can talk to each other using MoCA. If you’re talking about the environment, MoCA can coexist in a home with the “compatible” services, or no service. It can’t coexist in a home using the “non-compatible services” Compatible: Verizon FiOS/ Spectrum/ Devices with an Ethernet Port Not Compatible: Direct TV/Dish/Satellite TV/ AT&T Internet/ AT&T U-Verse I’ll save you some time and post the quick installation guide here to help get you setup. However there are pics on the installation guide that can help you out if you’re still confused. Step 1-Connect an Ethernet cable from the Ethernet port on one TMO-311C to the Ethernet port on your network. Step 2-Connect a coaxial cable from the MoCA port on the TMO-311C to the coaxial cable in your home. Step 3-On a remote TMO-311C, connect a coaxial cable from the MoCA port on the TMO-311C to the coaxial cable in your home. Step 4-Connect an Ethernet cable from the Ethernet port on the TMO-311C to the Ethernet port of a network device. I needed a better more reliable data rate from my NAS and gaming/streaming setup upstairs. Wifi just wasn’t cutting it even using mesh, and powerline didn’t come close to what I wanted. Now with these I’m near gigabit (was expecting way lower, but getting high 800’s low 900 mbps speeds!) 100% reliable. Impressive product. Solves a big problem, Easy solution If your router is in one room, and you want an Ethernet connection in another room (for a gaming console, switch, AP), and have standard coax wires connecting the rooms, BUT you don’t have Ethernet in those rooms or don’t want to run Ethernet, this is for you. Setup up on of these MoCA 2.0 adapters at either end of the coax, and boom, you just transformed your home coax into Ethernet. ## Frequently Bought Together - TRENDnet Ethernet Over Coax Adapter, Backward Compatible with MoCA 2.0, Gigabit LAN Port, Supports Net Throughput Up to 1Gbps, Supports Up to 16 Nodes On One Network, Black, TMO-311C - Cat 8 Ethernet Cable, 1.5Ft 3Ft 6Ft 10Ft 15Ft 20Ft 30Ft 40Ft 50Ft 60Ft 100Ft Heavy Duty High Speed Internet Network Cable, Professional LAN Cable Shielded in Wall, Indoor&Outdoor - G-PLUG 10FT RG6 Coaxial Cable Connectors Set – High-Speed Internet, Broadband and Digital TV Aerial, Satellite Cable Extension – Weather-Sealed Double Rubber O-Ring and Compression Connectors White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/262611198-ethernet-over-coax-adapter-backward-compatible-with-moca-2-0](https://www.desertcart.kr/products/262611198-ethernet-over-coax-adapter-backward-compatible-with-moca-2-0) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-12*
