Hello, I have the password for a wifi. Now usually i could go into the router and search in it for the WPS pin. But this router is a cheap Nexxt model and i cant find the pin, but i know they're always at the back of the router which i cant get to. I need the WPS pin in case the person tries to change his password. Then it be easy for me to get the new pasword by using the WPS Pin. My question is can i retrieve the wps pin using the wifi password. Thannks so much,
