This device converts your RJ45 internet (ethernet) signal into MoCA Coaxial. Use your ethernet-over-coax connection between your access point and your router to improve your WiFi connection. | Important: please buy at least two devices to enjoy the high speed MoCA - you need one device to convert to ethernet-over-coaxial, and another to convert the coaxial connection back to a signal your router/computer/game system can use. They can be connected to a variety of devices in the home. Maximum 16 devices in every home network. | Use existing COAX wiring to create an ethernet network to achieve a fast, reliable Ethernet connection between a router and any device with an Ethernet port. MoCA technology outperforms wireless for speed, latency, reliability, and security. | 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. Plug and Play set up with no need to configure the Coax to Ethernet Adapter or re-configure your router. | 👍Compatible with any Ethernet router & virtually any device with an Ethernet port including computers, Xbox One, PS4, Roku, Nintendo Switch, streaming media devices, DAC's and more. See below for non-compatible devices. ❌ Not compatible with Direct TV, Dish or other satellite TV, AT&T internet, or AT&T U-verse coax networks. *WARNING: ❌ This product WILL NOT work if the coaxial cable in your home is also being used for cable TV and/or Internet Services (eg. Cox, Xfinity, ATT, etc.)
