I've got a SWM sat and HR24 in the Den. Directly besides my main setup in this Den is my cable modem and router, and a connected DECA for whole home DVR. We have an HR22 in the living room on the MRV setup, works without a hitch. In my sons room there is a D12, so no internet or MRV access in this room. I'm not looking to upgrade his receiver at the current time, but do want to add a media box to his room. So going through the DirecTV DECA, what do I need to buy for his room to get on the internet? This? http://www.solidsignal.com/pview.as...DECA--(DECA1MR01)&c=Satellite Components&sku= And this? http://www.solidsignal.com/pview.as...DER0)&c=Satellite Components&sku=874409002374 And lastly this? http://www.solidsignal.com/pview.as...p-Filter-(BSFR01)&c=Satellite Components&sku= Lastly, can I come off the DECA into his room into a switch to expandability in the future? Thanks in advance!! Edit: Found these - DECABB1MR0-01 (http://cgi.ebay.com/DirecTV-WholeHo...ultDomain_0&hash=item4aa5d2057a#ht_500wt_1156) Is this all I need?
