|I would reset the router to factory defaults. |
To do so, simply hold the reset button in for 10 seconds while the unit is on. Then release. Once the unit is done booting up it should be reset to factory defaults and you can then access it's management interfafce using your web browser and the default IP address listed in the setup guide/manual
I would highly recommend updating the firmware on your unit after you get it reset (before doing anything else) and once done, then reconfigure it.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
