A:Answer I have the feeling that you did not connect the extender to your router.
I am no expert but you need to initially set up the extender very close to the router. This lets it acquire the correct wireless signal.
BUT you have to connect it to your router, just like you have to do for your computer or your phone. One way is to use the automatic connector where you push the WPS button on the extender AND the WPS button on your router. If you can't do this, then you have to browse into your extender using the url: http://www.mywifiext.net and enter your router wifi ssid and password manually. The green lights should come on.
Then you can take it to the area that you want to extend the signal to. I recommend that you download the free phone app, "Wireless Analyzer" to see the signal strength wherever you are and you can place the extender where it's signal will be the strongest.
