Chapter 20 Troubleshooting

NBG-416N User’s Guide

Make sure you have entered the password correctly. The default username is 
admin and default password is 1234. This field is case-sensitive, so make sure 
[Caps Lock] is not on. 

This can happen when you fail to log out properly from your last session. Try 
logging in again after 5 minutes.

Disconnect and re-connect the power adaptor or cord to the NBG-416N. 

If this does not work, you have to reset the device to its factory defaults. See 

I cannot access the Internet.

Check the hardware connections, and make sure the LEDs are behaving as 
expected. See the Quick Start Guide.

Make sure you entered your ISP account information correctly in the wizard. These 
fields are case-sensitive, so make sure [Caps Lock] is not on.

If you are trying to access the Internet wirelessly, make sure the wireless settings 
in the wireless client are the same as the settings in the AP.

Disconnect all the cables from your device, and follow the directions in the Quick 
Start Guide again. 

Go to Maintenance > Sys OP Mode > General. Check your System Operation 
Mode setting. 

• Select Router if your device routes traffic between a local network and 

another network such as the Internet. 

• Select Access Point if your device bridges traffic between clients on the 

same network. 

If the problem continues, contact your ISP.

I cannot access the Internet anymore. I had access to the Internet (with the NBG-
416N), but my Internet connection is not available anymore.
