I am moving at the end of the month to another house (not very far away from where I live), but Uverse is more limited there than at my current house. So I bit the bullet and went with Comcast. The big advantage is that I am on the Extreme 250 tier (250 Mbps down / 25 Mpbs up) which is way faster than I have ever had before.
I want all the outlets to take advantage of this speed, and rewiring a 2-story house for ethernet can be expensive. So I decided to go with MOCA adapters, and will use 4 for now.
I think the best spot for my cable modem will be in my media/bonus room. That way I can hook up my cable modem and MOCA adapter using a splitter, and then connect my cable modem to my router. I will also have a PC, Tablo, Roku, and a Blu-Ray player all hooked up to my router (which is how I have it in my current home).
I will put one MOCA adapter in my office, though since I have a work laptop and gaming PC in there, I will need a switch. Another will go in my daughters work area for her computer, and the last will go in the room with my wife’s computer. I plan on just using wireless media streamers for my bedroom and living room tvs, though I could always buy one my pair of adapters.
I am using these adapters ( http://www.bhphotovideo.com/c/product/1179504-REG/actiontec_ecb6000k02_moca_2_0_network_adapter.html ), as well as a filter ( http://www.amazon.com/gp/product/B00DC8IEE6?psc=1&redirect=true&ref_=od_aui_detailpages00 ) that will be put on at a spot before the cable is split to the rest of my house.
