Dish and Comcast Internet on same Coaxial Cable

    Recently I had the Disk Network Hopper and 3 Joeys installed at my house. The joey in my computer room shares a cable with my Comcast cable internet service. I never had a problem running my satellite tv and cable internet through the same coaxial cable until now. Prior to switching to Disk Network, I had Directv and it worked fine sharing a coaxial cable with my Comcast cable internet. I had a 5/2150 2-way splitter combining the signals at the junction box on the outside of my home and another 5/2150 2-way splitter separating it at the outlet in my computer room.

    The Disk Network technician tried this same hook up using 2 Holland 5/2150 HFS-2D splitters and it does not work. The satellite signal comes through fine, but the cable internet will not work. When I connect it with using the old splitters that worked when I had Directv, which is an Aska 5-2150 Diplexer on the combining end and a Holland DPD2 5-2150 on the splitter end, the Comcast internet signal comes through fine, but the satellite does not work.

    I would really like to run the satellite and cable internet through the same coaxial cable. Do I need a special signal combiner/splitter?

    Any help is greatly appreciated.

    If this is not the proper forum for this post, please let me know.

    #1 - get separate cables for the Comcast Internet and your Dish. Sharing cables is a surefire entry into fingerpointing between providers.

    #2 - You have to use Diplexers in PAIRS. However - I don't know what frequencies the Joey is using, so again - go back to separate cables. They may very well be using the same band. If you didn't have the Hopper / Joey setup - then your old DirecTV setup using the diplexers would have worked.

    #3 - There maybe some other network technology (ethernet, wifi ?) to connect your Joey to the Hopper, and leave the coax cable for the cable modem..

    Most Hopper/Joey setups are not designed for coax to work with other providers due to the number of frequencies they need to use. A separate run for your internet is the best possible solution.

    You cannot combine them at all. The Hopper requires the entirety of the cable's bandwidth.
