I did a search for this problem and after 120 of 203 posts, didn't find anything that addressed this problem close enough to sound like it would work. Just bought a 322 for the RV from a private party and spoke with Dish CS and all is well with them and the receiver. Have an upgraded purple smart card. I'm using a Dish 500 antenna with DishPro+ LNB. Several problems during initial set up but after purchase of the Dish CS recommended diplexer and triplexer I have the 322 set up as the 722DVR at home. All is not well. Can only find satellite 110 in the RV. Will not download information even with a signal strength of 82. Never could get 119. Check switch would show the 110 connected and per Dish CS the check switch tests showed all wiring is good. Brought the receiver home and using the 322 triplexer, hooked it up to the 722 cable in (there is a diplexer in the line). Found 119, no 110. Went to the download current software screen and an hour later no change (no progess line). Checked point satellite screen and, no 119 but good signal for 110. Have a single TV HD receiver in the living room and no diplexer. Will try it with that TV next. Any ideas?
