Why my DAP-1620 cannot be added to my router when used with WPS button?
Since WPS button is not a standard between brands, we can advise to proceed with the manual installation on a PC.
To access the setup utility for the DAP-1620 AC1200 Wi-Fi Range Extender on your PC, first connect to the DAP-1620 wirelessly using the Wi-Fi name (SSID) and password located on your Wi-Fi Configuration Card. Then open a web browser and enter http://dlinkap.local./ in your browser’s URL field.
