I've had my MRV for a couple of days, and recently one of my receivers has been losing connection to the network. It says something ot that effect on one of my receivers. It is an original HR-20. I'm trying to resolve why the installer's did a few things which probably don't really affect this situation, but I'm still wondering. I've got 4 DVR's and 1 HD box, so they brought (I had to figure out with the help of the forum how to a hook it up) a SWM16. Off of SWM-1 it goes upstairs to my power inserter. On the PI IRD link, there is a 1 to 4 Splitter. This splitter I don't really understand why htye've hooked up the way they have. One port goes to an HR24, Another port goes to a white DECA and hooks up to my gigabit switch, and another port goes to a 1 to 2 splitter that goes into an HR20 with one port going to one satellite input, and the other going into a white DECA and going to the other satellite input and also to the ethernet port. The final port of the 1 to 4 splitter is terminated. Is the 1 to 2 splitter even necessary? Couldn't these two ports just be on the 1 to 4 splitter since one port on the 1 to 4 is terminated and the other goes to the input of the 1 to splitter? This seems to just introduce unnecessary signal attenuation, IMO. Also, in the location that's not seeing the whole MRV playlist and is losing the connection, they also have a 1 to 4 splitter with only two of the ports used. Again, one is going to the HR20 satellite input, and another is going to a white DECA unit that is going to the second satellite input as well as the ethernet port on the HR20. The other two ports are terminated. Again, this splitter seems to be overkill and just causing extra signal attenuation. I'm thinking of just moving the 1 to 2 splitter that is upstairs down to this location. But, I hate to go do this if there is a reason the installers have done it that way. Also, any ideas to try to make the downstairs HR20 continuously able to see the whole home playlist? Thanks!
