NBG5715 User’s Guide

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

If you reset the NBG5715, you lose all of the changes you have made. The NBG5715 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 NBG5715:

Make sure the power LED is on.

Press the RESET button for longer than 1 second to restart/reboot the NBG5715.

Press the RESET button for longer than five seconds to set the NBG5715 back to its factory-default 
configurations.

If the NBG5715 restarts automatically, wait for the NBG5715 to finish restarting, and log in to the 
Web Configurator. The password is “1234”.

If the NBG5715 does not restart automatically, disconnect and reconnect the NBG5715’s power. 
Then, follow the directions above again.

I cannot access the NBG5715 or ping any computer from the WLAN.

Make sure the wireless LAN is enabled on the NBG5715. Check if the WLAN button is at the ON 
position. Or you can enable the wireless LAN in the Network > Wireless LAN 2.4G/5G > 
General screen.

Make sure the wireless adapter on the wireless station is working properly.

Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports 
the same wireless standard as the NBG5715.

Make sure your computer (with a wireless adapter installed) is within the transmission range of the 
NBG5715.
