wifi splitter and extender question
AT&T is my ISP and provides the router. I recently installed a Rheem Econet thermostat and Rheem informed me that I need to add a wifi splitter or wifi extender in order to add the thermostat onto the network so that I can get the app to work. Can anyone confirm this and what is the appropriate equipment I need to add. Thank you.
