Thank you for the feedback. 

If the 5Ghz LED light is ON but 2.4Ghz Led is off on the range extender, the RE has successfully connected to 5Ghz Wi-Fi band of routers and you should have internet from the extender's Wi-Fi network. 

To link 2.4Ghz Wi-Fi, you could try a factory reset on the range extender and reinstall it.  WPS button is not a necessary way to set  up your range extender, you could try to install RE from its web page or Tether app.
