Try resetting the router this way,
Use a pen or paper clip to push in the reset button and hold it for 30 seconds, after 30 seconds (still holding in the reset button) remove the power cord and wait for another 30 seconds. Last, (still holding the reset button) plug the power cord back in and hold for 30 seconds then let go.
