I do not currently have MRV. HR22-100 in family room, HR20-700 in master bedroom and H23-600 in computer room. Dish connected through SWM. I would like to have internet connected to all of the receivers, but would rather not go the wireless route. Would the following work: Add a DECA to each receiver and run an ethernet cable from the dsl modem/router directly to the DECA of the H23 (plus a second ethernet connection to the H23). If this configuration works, what else would be required to have MRV up and working? Thanks!
