If your router configuration pages stop responding, unplug and then plug back in the power supply of the Wireless Ndx Router. This will reboot the Wireless Ndx Router. If you are still unable to communicate with the router configuration pages, press in and hold the Reset button for 7 seconds. This will reset the Wireless Ndx Router to the factory default settings. If you made any personal configuration settings, you will need to make the changes again or restore your settings if you created a backup file.
