When we try to setup the Netgear wireless range extender sometimes we place it veer far away from the place where our router is. If the distance would be very large while we are setting up the Netgear wireless range extender, it would not be able to communicate properly with our wifi router. It would not be able to receive signals properly from our wifi router. Due to which sometimes it will get good reception but sometimes it would be not up to the mark.
