I have three receivers, 1 H24/100 and 2 HR24/200's. I have multiroom viewing. I am trying to connect my system to the internet for on demand stuff. Originally the installer left me with a black box (DECABB1??). It has three led's (Clink, Power, Network) but he never could get it to work. I called Direct Tv and they said I don't need a DECABB??, that what I need is a different adapter. So they sent me the following (with no power supply): I am wanting to connect my system to my network at home. My network functions properly, no issues. I have a cat'5' jack next to my receiver (working per laptop plugged in). My dhcp server supplies 172.18.122.* ip addresses. Attached is crude drawing. Everything I have read leads me to believe I originally had the correct equipment to get connected (the DECABBxx) black box. The black box with "?" is where I have installed it. The Power, clink, and network light stays green when connected. When I run through the internet connection setup, everything checks out but the "Connect to Internet". Do I have the right equipment, or do I need to get Direct Tv to send me the power adapter fo rthe "Connection Home Adapter" and use it ? I am so frustrated with Direct Tv I don't know what to do. Everytime I call they tell me something else. thx so much if you can help.
