How can I turn off a Cisco modem/router's "Wi-Fi Protected Setup"?

Question

My modem/router, a Cisco EPC3925, has something called "Wi-Fi Protected Setup" or "WPS", preventing me from changing certain settings. This includes turning wireless off altogether.
This feature hands over control of said settings to my ISP. Thus, if I want to turn of wireless, I need to contact them.
I'd like to turn off this "WPS", so I regain control. There is a checkbox on the web interface for "manual" control, but it is disabled.

Answer 1

log into your router through IE or chrome.. etc e.g. http://x.x.x.x

Then follow these steps.
1. Go to wireless
2. Basic settings
3. there should be a configuration type manual/WPS

Hope this helps.
