Hi,

WPS/RESET Button     |    Press and hold this button for more than 5 seconds until the LED blinks to

                                           reset the router to its factory default settings.

I would like you to buy a better and more expensive router model and you will do best if it is not from the company TP-Link, Pay attention to the companies Netgear, Asus, Xiaomi. Of course if you have the Desire, Time and Opportunity Yes Allow Him
