Reboot the NBG4615.

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

• Check the settings for QoS. If it is disabled, you might consider activating it.

If you reset the NBG4615, you lose all of the changes you have made. The NBG4615 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 NBG4615:

Make sure the power LED is on.

Press the RESET button for longer than five seconds to set the NBG4615 back to its factory-default

If the NBG4615 restarts automatically, wait for the NBG4615 to finish restarting, and log in to the 
Web Configurator. The password is “1234”.

If the NBG4615 does not restart automatically, disconnect and reconnect the NBG4615’s power. 
Then, follow the directions above again.

I cannot access the NBG4615 or ping any computer from the WLAN (wireless AP or router).
