Been with Directv for less than 2 months and brand new to this forum. Was a long-time Dish Network customer with older equipment so still trying to figure out this stuff about Genies and Clients and SWM's and Splitters (oh, my!). I recently had a SL3 slim-line dish, HR54-500, and one, wired C51-500 Mini installed at my Northern residence. Installer reused existing Dish Network cabling (just using one of the twin cables from old dish location to new splitter). Having recently gone south for the winter, I purchased and self-installed a new SL3 slim-line dish (only difference I can tell is that this one has a RB LNB vs non-RB on the northern dish). I have been able to get a very good satellite signal (96-100 transponder levels on 101) and the HR-54 connected to my main TV works great. My problem is that my mini client located in the bedroom when turned on says "Connecting" and then gives a message saying, "Directv network connection not found. Check cabling." I have checked all cable connections and even tried a different cable from splitter to C51. I have tried re-setting the HR-54 and C51 (both at once and individually), all to no avail. I am wondering if perhaps the splitter is the problem (it's 8-way, green label). I did use a 50ft CCS cable to run from LNB to splitter because I couldn't find solid core, but with the HR-54 working so good I tend to think that is not the problem. Anyone have any ideas of what the problem could be. I ordered a new 2-way, green label splitter to try but it hasn't arrived yet.
