How do I enable wi-fi protected setup (WPS) on my Cisco DPC3941T router?
Solved! Go to Solution.
There should be a button for it on top or the front of the device.
As an FYI, WPS has a security vulnerability. You can Google for more info. Never use it. Disable it and always configure your WiFi settings manually !
