Did a few searches, but didn't find what I'm looking for so.... I'm here to pick your collective brains. Situation: Two story house, lots of interior brick, hell on a wifi network. My internet/cable are Comcast (ugh); the network equipment is in a basement storage room with a cable outlet. I use my own modem, a Motorola Surfboard SB6120. Current set up: In the storage room, wall > coax > modem > ethernet to Time Capsule (provides wifi) ...Also, Time Capsule > ethernet to Ooma phone base Upstairs, two Airport Extremes to extend network (connecting via wifi) Problem: So much stuff is on the wifi, it's dropping and/or crawling. I know part of the problem is that I'm fighting all this brick with two Extremes running off wifi only. As for hardware on the wifi, well...two TiVos (with a third on the way), three computers (two of which backup wirelessly to Time Capsule...plus all three backup wirelessly to CrashPlan), two iPads, an iPod, and Apple TV. The goal: To pull the three TiVos off wifi entirely (since they chatter so much) while pumping up the wifi strength and stability throughout the house. What I want to try...if it will work: MoCA. My understanding is that there need to be four adapter boxes-- 1. (Basement, storage) Cable outlet > MoCA > modem > Time Capsule 2. (Upstairs) Cable outlet > MoCA > Airport Extreme > ethernet to TiVo #1 3. (Upstairs) Cable outlet > MoCA > ethernet to TiVo #2 4. (Basement, office) Cable outlet > MoCA > ethernet to TiVo #3 And for good measure, a MoCA PoE filter in the garage, before the splitters and booster. My questions: 1. Does this set up make sense? 2. How will the TiVos locate each other? Since they won't be in a common wifi network any more, is there a new wired network name, or will they simply show up on each other's programs list screen like magic? 3. Is there any hiccup in connecting the Airport Extreme between the MoCA adapter and a TiVo? All these years, and I can't for the life of me recall how wired setups work. Go figure. Thanks in advance for your wisdom.
