how to do reset the password on a nighthawk X4S extender

[jedaraine]

I forgot the password to my nighthawk X4S mesh extender (havent used it in a while).

I did a factory reset but it did not remove the wifi systems I had used previously.  Just wanting to set up on a new location.

When you reset, did you push and hold reset fo r7-15 seconds while it was powered on? 

Many make a mistake and only click on the button.
