My set up: Storage room Cable line into the house > Cable modem, Time Capsule, and MoCA. This room is the heart of house wifi network. Upstairs bedroom Cable outlet > MoCA box > TiVo Premiere It works for the TiVo, but...sure would like to add a second Airport to the bedroom, extending the otherwise weak wifi signal to that part of the house. Is that possible? Where/how do I add an Airport to the bedroom setup?
