How to connect a WIFI extender to the smart hub? I have to WIFI extenders connected which automatically connected when powered up, i want to add a third but I cannot? I tried the mytelus wifi, but the extender I want to connect, I need to connect it to the smart hub through the ethernet cable without disconnecting the primary WIFI extender. The smart hub only has one ethernet connection? So I cannot connect the third WIFI Extender. Is there anyone out there that knows how to get the third WIFI Extender connect to Smart hub?
