Congratulations on fixing your problem, feels great doesn't it.
I had the Dish traveler installed in the roof because I wanted to have their Hopper setup so I could copy shows while at work. My wife schedules my last appointment at 7PM as a result some nights I don't get back to the rig till 8:30 or 9PM. I tried to put the hopper in the salon and the joye in the bedroom. No joy with this setup and I thought I had a bad Hopper as did the Dish tech I had on the phone. They sent me a new hopper but again no joy.
Ok the fix. I remembered that when the tech installed the Dish system in our stick house he located the hopper in the master bedroom as that was where the RG6 cable came in straight form the Dish on the house.
On the rig the traveler on the roof is in the front of the rig and the RG6 cable runs directly into the bedroom then splits to the salon. The cable from the bedroom to the salon its RG Crap 💩 or whatever so the signal was for too degrated to travel to the hopper. Once I figured this out I moved the Hopper to the bedroom so that it had a direct RG6 cable from the travler to the hopper. As for the Joye it is quite happy with RG crap cable so it is now in the salon. Called Dish and they started the system up and all is good. My happy meter is pegged.
