Disable the WSP feature for the R7800 — Nighthawk X4S AC2600 router

Might look under Advanced tab/Advanced/Wireless settings on the routers web page for any WPS options. 

Generally, if WPS is enabled, devices won't see or use it unless you actively try to connect using it and press the WPS button on the router. Generally if you direct the device to the routers SSID name and input the password for the SSID named network, is all that's needed and preferred. This won't be effected if WPS is enabled or disabled. WPS is only active for a short 2 minute period of time when the WPS button is pressed.
