Yea I just went outside and took the box off the wall. There is a SOLO NODE as you described. The wire are color coded. Blue for the Hopper and a splitter off the node with Black and Red. I can just swap the blue and either the black or red right?
If it's a node, then you have a Hopper or Hopper with Sling, not a Hopper 3. Wiring of the Hopper 3 is completely different.
Color-coding won't help. These were probably done by the installer to help identify which cables go where.
If as you say, you have a SOLO NODE, you will have two coax cables coming from the dish and connected to the TO DPP PLUS... connectors. The Hopper will be connected to the TO HOST port. Your two Joeys will be connected to the output of the splitter connected to the TO CLIENT port on the node.
You will need to identify the coax that is connected to the Joey in the front room where you will be relocating the Hopper. I suspect you'll find color codes consistent with those you found in the box outside. If not, you will need to pull one of the cables off the splitter and see which Joey lost it's signal.
Unplug and disconnect the Hopper from the coax in the bedroom. Move it to the front room but don't connect it yet.
Unplug and disconnect the Joey in the front room's coax. Move it to the bedroom but don't connect it yet.
Go to the box outside and swap the coax connected to the TO HOST port on the node with the cable you identified above.
Connect the Hopper to the coax cable in the front room and the TV. Plug in the Hopper and allow it to boot. You should now see a picture.
Connect the Joey in your bedroom to the coax there and to the TV there. Plugin the Joey and allow it to boot. You should now see picture there also.
Finally, go to your other Joey location and verify you have picture there too.
