A:AnswerIts all on the same wifi network but you have the options to choose what is connected to each wifi extender with the app that goes with it. Connecting
wps method is the easiest.
A:AnswerYes. You can set it up using wired or WPS on your router and extender. It has an Ethernet port on the bottom so you are able to connect it to any device that accepts Ethernet. I have it wired, but will sometimes move the extender closer to my gaming console and plug it in wired.
A:AnswerFrom my experience, no it cannot, I had the most frustrating time trying to get this thing to stop disconnecting from my internet, and my room is probably 80 feet away from my main router as well. When it would connect for the brief 10 minutes that it would my internet was quite good, but it was not worth the hassle of constantly reconnecting it to my internet every 10 minutes.
