I am connecting a 2800 receiver to a DP34 switch. I purchased a used Dishpro Adapter from ebay. I am only receiving 110 odd. When I do a check switch the Installed Switch Model says UNKNOWN and the Status is No Switch box detected. This is a brand new RG6 cable run and to confirm that the problem was not the cable, I took the receiver and adapter to a working room and saw the same thing except I only got 119 odd in that room. This receiver was working fine on my legacy setup last month. Do you think I bought a bad adapter? I would appreciate any ideas.
