Mrs. Fluffybear and I are having dinner with friends when the conversation turned to DirecTV Whole Home Service. Knowing that we have the service, I was asked if I might be abel to troubleshoot an issue. After looking at the system and wiring, I'm completely lost, so here goes: System consists of 4 HD DVR's (HR21's and 23) connected to a SWM-16 All the units are working properly and are hooked up correctly. The DECA Power Supply is connected in the living room to the router. All the lights are green and everything appears to be fine. The other DECA Units also have green lights and appear to working just fine. Here is where it gets strange: DVR 1 can see DVR 2 DVR 2 can see DVR1 and DVR4 DVR 3 can see DVR2 (DECA Power Supply located in this room) DVR4 can see DVR1 We have rebooted the system, moved the DECA units around, set static IP addresses, went back to dynamic IP addresses and still no change. So anyone have any suggestions?
