Hi. My name is***** you for you question and the opportunity to assist.
With the router powered on, have you tried holding the reset button down with something like an unfolded paper clip or a pen?
If using a finger it may not be getting pressed down quite far enough to cause the router to reset.
With the button properly held down it should take no more than 10 seconds to start the reset.
Hi. I haven't heard back. Were you able to get the router to reset?
