A:Answer These are routers. Of the three, one is directly wired to your modem. This one is the "gateway" eero. The others can be wired to this gateway, or can be set up wirelessly. They all will communicate with each other, but the gateway is the one broadcasting to the rest. You can add more eero's if you need more coverage. According to eero, all eero's will work with any other eero's, as well. Maybe you just need to re-position your eero's to have better overlapping signals.
