How to setup two or more than two extenders? If we want to use two or more than two extenders at our home, we have to setup these extenders one at a time. Suppose if we purchase three extenders, so, first-of-all we have to setup first extender. Once the extender is setup, then we have to unplug it and plug in the second extender. After setting up the second extender we have to unplug it and plug in the third extender. After setting up the third extender we could place these extenders anywhere in our home where we were having all the problems with wifi reception. http://www.mywifiext-net.com/contacts.html
