Yeah...should have mentioned I did a reset before I posted. Didn't work.
I've had nothing but trouble since the splitter on my system went out and DTV sent out a guy to replace it. Actually I was getting an error about the receiver not seeing the SWM. He replaced the coax from the dish (don't know why he didn't try the splitter FIRST - seems it would have been a lot easier), then the splitter. I went on vacation for 2 weeks the next day, and 3 days after I returned, I lost my whole home. The HR22 was fine (That's hooked directly to the DECA), but the HR24 couldn't access the internet and the message I got was "No networked DVRs found". I browsed this forum and found a post about the internal DECA(?) being inadvertently disabled. I went through a "Satellite Setup" and did a reset and everything is now fine. The HR22 has become EXTREMELY slow - taking as much as 30 - 45 seconds to change channels, or for the guide to come up after you hit the button.
I did a reboot on it and when I got the message that the receiver was doing a self check, hit the select button and ran all the Built In Self Tests (BIST). Everything "PASSED".
Pretty frustrating all around. Wife is threatening the switch to Dish :-)
