When I press WPS on the Tplunk 1609 no light is turned on. If I go to the https address the advanced option for wireless- WOS does not show any option to tick a box that enables the WPS. It simply has WPS heading with no option underneath.
I just tried to login to 192.168.1.1 on another device and was successful in enabling WPS as shown here in steps 1-4. My PC didn’t give me the enable option but my iPad did.
