That's one thing, have you tried accessing it on other computers already?
Resetting would set your router to default. It also may be getting an IP conflict but if that is the case, if you are going to reconfigure your router, try a different LAN IP address like 192.168.2.1 just to make sure it is out of range. If you would still not be able to access it after the reset, you may opt to re-load your firmware.
After reloading the firmware, you have to reset your router for about 30 secs. and reconfigure it for your Internet connection.
Try accessing it afterwards. Goodluck!
