If the wireless option on the printer is missing, you will have to access the EWS page of the printer to activate it.
To access the EWS page, the printer should be on a network. If you have an ethernet cable, connect the printer and the router using the cable and obtain the IP address of the printer to enter in a web browser.
If you do not have an ethernet cable, the only other option is to perform a reset on the printer which you have already tried.
