Chapter 26 Troubleshooting

3Reboot the NBG-460N.

4If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions.

Advanced Suggestions

•Check the settings for bandwidth management. If it is disabled, you might consider activating it. If it is enabled, you might consider changing the allocations.

•Check the settings for QoS. If it is disabled, you might consider activating it. If it is enabled, you might consider raising or lowering the priority for some applications.

26.4Resetting the NBG-460N to Its Factory Defaults

If you reset the NBG-460N, you lose all of the changes you have made. The NBG- 460N re-loads its default settings, and the password resets to 1234. You have to make all of your changes again.

You will lose all of your changes when you push the RESET button.

To reset the NBG-460N,

1Make sure the power LED is on and not blinking.

2Press and hold the RESET button for five to ten seconds. Release the RESET button when the power LED begins to blink. The default settings have been restored.

If the NBG-460N restarts automatically, wait for the NBG-460N to finish restarting, and log in to the Web Configurator. The password is “1234”.

If the NBG-460N does not restart automatically, disconnect and reconnect the NBG-460N’s power. Then, follow the directions above again.
