We have 3 receivers (All HR-24) connected through the DECA. Everything was working fine up until about 3 weeks ago. Now, one of the DVRs gets dropped several times a day and another gets dropped a couple of times a week. However, they all come back on their own, sometimes within just a few minutes. So, for example, sitting in Family Room and get a message saying Master Bedroom connection lost. However, an hour later, the Master Bedroom is connected again and I can see and access the shows. Any thoughts?
