A:AnswerEERO is a wireless router so it would not work as a Wi-Fi extender. The EERO satellites are made to work with the EERO hub router only. I would recommend getting a wi-fi extender vs trying to make the EERO work.
A:AnswerMine goes thru 2 block walls and 30 feet. I place a EERO unit in my office location (2 block walls between here) and a EERO unit at the Modem. Then the 3rd EERO unit at the complete other end of my house next floor up and works great. I'm no expert but possibly make sure your Modem is strong. I also paid to have Best Buy tech install mine to insure it worked.
A:AnswerYou can, they all work together as long as your main eeros is plugged directly into the modem, all others are simply added into the family of eeros devices. They work seamlessly.
