I Can't connect Netgear AC750 range extender to Netgear N300 router. There is no WPS button on router and instructions say to push that button.

You didn't specify the model of your Netgear router. N300 is a speed class. In any case, many Netgear routers have a "soft" WPS button that is available on one of their setup screens.

Alternatively, you can log into the range extender and manually enter the SSID and Wi-Fi password from your router. Consult the manual for the extender for instructions.
