A:AnswerYou have to go through a setup process & sync it to your main router. And don't forget to name it's network the exact same name as your main unit.
A:AnswerYes! This unit extends the range of your wifi signal. The previous answer is incorrect as they are speaking to the data speed, which this unit does not effect. So better range to connect to wifi, not better speed.
A:AnswerI don't know how your system is set up, but the NETGEAR AC750 WIFI RANGE EXTENDER needs to be able to actually receive a signal from your router in order for it to boost the signal. I would think it would have to be plugged into an upstairs electrical socket where it could then boost it across part of the second floor. I suggest you check to see if there is any WiFi signal anywhere upstairs first. Do you get a WiFi signal for your phone upstairs from your router?
A:AnswerYou can plug it in anywhere that has signal from the main router. Just use the signal strength meter on your phone to find out if you're in range.
