2 PACKS - DIRECTV Broadband DECA Ethernet to Coax Adapter - 3rd generation (with 2 AC power supplies) : I was looking for a way to get Ethernet into the corner of my house where Wi-Fi just isn't enough to connect my TV, BlueRay player and Fire TV. Wiring was out of the question due to the gas fireplace and a few other obstacles preventing a clean flow. I tried using a Wi-Fi extender but the connection kept dropping. I then tried the Ethernet Powerline Kit, but due to some issues, that also resulted in an unstable connection. The existing coaxial line was the only "port" leading to the garage where all other cables go. Took a picture and ordered this DECA kit and bam. A reliable, stable ethernet connection was created and with the help of a small 5-port ethernet switch, all my devices are now connected to my home network and Interwebz. Installation is easy: I put a device in the garage and connected it to my existing home network. via an existing switch. I connected the coaxial line to the device, then connected the power supply. On the other end of the coax (above) I connected the coax from the wall to the second device, ran a short ethernet cable from the device to a small 5-port switch (TV, Fire TV and BluRay connected to the switch), then connected to the power supply. Within about a minute the light stopped blinking and became solid, indicating an established connection - now I had a 100MB connection where I needed it. If you check your router settings, you'll find that each device connects via DHCP and gets an IP address. It is in order . It's just the way they work. Note, however, that you have a new item for each connected device. This setup has been running stably for about 8 months without any problems. I noticed something strange the other day: a transmitter in a garage with a DHCP name "che" (assigned by the device) regularly initiates downloads from IP addresses originating in China. With an OUI search on the web, I was able to confirm that the activity was coming from the device. At first I thought it was new firmware or something, but when I examined the amount of data I was amazed. Some days the device downloaded up to 1GB and regularly showed around 300-500MB during daily activities. I was beginning to think it was just connections to Netflix, Revain Video etc but there was activity on days I wasn't even home. I then blocked the devices from accessing the network using the router settings and found that I was still able to use my internet-connected devices with no problems. Internet research shows that this is often caused by the device downloading new firmware but not loading. It downloads the firmware over and over again. Nothing bad happens, it's just bad code. All in all, the devices work as intended - they provide you with a 100 Mbit Ethernet connection via coaxial cable. If you need speeds over 100 then you should use MOCA rather than DECA adapters but for general online video etc they work fine and I would use the same solution again if I find myself in a similar situation elsewhere would. Rated 4 stars instead of 5 due to a download issue. Recommendation: Set it up, check the connection, and then block Internet access through the router. It worked fine for me.
