Yes, I have 2 SWM16s. I say that not because I'm an expert, but because I heard the techs talking about it. What do they look like? I'll try to find them and see about connecting them with Ethernet and DECAs. I have never seen a SWM16 or a DECA. I'm sure I can figure it out though. So right now I have 5 HR24s and the HR34 on the whole home group (and presumably all connected to the save SWM16) and then the HR21 all by itself (presumably connected to the other SWM 16). Would I just connect a DECA to an available coax connection on the SWM16, run Ethernet from that, and connect it to another DECA on an available coax in the other SWM16? This sounds easy enough to do if that's all there is to it. I bet the SWM16s are right next to each other, wherever they are. There are 2 things connected to coax in the closet next to my router that the tech said not to ever disconnect (and I think they're connected to power). Would those be the SWM16s?
