A:AnswerYes, the modem is needed for your broadband connection to your ISP. You will drop only the TV service from your contract and keep the internet service with the cable company if you are happy with them or you can switch to another ISP if the cable internet is bad. You will need good Internet service for streaming and the modem is the gateway to the internet.
A:AnswerYes, this should work fine. You will have one eero hardwired to that modem. The other eero can connect either wirelessly or wired to the head/gateway eero and they will broadcast the same network, extending the range and speed you can get.
A:AnswerI have a 2500sf, 2 story house and was getting 7mbs, the router is upstairs and I still get 650+ mbs downstairs.and everyone is on they're phones, tv's or computers.
A:AnswerThat was my main reason to buy the pro 6. The pro 6 has a tri band Wi-Fi system and if you have smart home devices this one is the choice. The standard eero 6 is dual band only and therefore more devices share the same band thus congested traffic
A:AnswerThe first eero should be hardwire to the modem. If you can hardwire the on to the basement they be better but if not you can use the other two wireless.
