NBG6716 User’s Guide

Disconnect and re-connect the power adaptor to the NBG6716. 

If the problem continues, contact the vendor.

I don’t know the IP address of my NBG6716.

The default IP address of the NBG6716 in Router Mode is 192.168.1.1. The default IP address of 
the NBG6716 in Access Point Mode is 192.168.1.2.

If you changed the IP address and have forgotten it, you might get the IP address of the NBG6716 
in Router Mode by looking up the IP address of the default gateway for your computer. To do this 
in most Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP 
address of the Default Gateway might be the IP address of the NBG6716 (it depends on the 
network), so enter this IP address in your Internet browser. 

If your NBG6716 in Access Point Mode is a DHCP client, you can find your IP address from the 
DHCP server. This information is only available from the DHCP server which allocates IP addresses 
on your network. Find this information directly from the DHCP server or contact your system 
administrator for more information.

Reset your NBG6716 to change all settings back to their default. This means your current settings 
are lost. See 

 in the Troubleshooting for information on resetting your 

NBG6716. 

I forgot the password.

The default password is 1234.

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

.

I cannot see or access the Login screen in the Web Configurator.

Make sure you are using the correct IP address.
