Hi all. Longtime quite member. My receivers: HR24-500, HR21-200, R22-100, HR20-700, HR24-100. This past weekend I converted over to SWM which I got from a customer that switched to Dish. It went well everything is working. All but the HR21-100 (kitchen) are MRV wired Ethernet connected to my router. I have no wired Ethernet to the HR21-100, and prior to SWM it was a single tuner. i would like to add MRV to it. I do not have DECA or MOCA. My system is all self installed since I built the house in 2000. I rely don't want a installer here because I "moved" due to local networks issues. Can i add DECA to my system and will DTV send me one? Other options? Usually DTV will send me new equip if it fails, been a customer over 20 years. Thanks for any advise?
