I forgot the IP address for the NBG-318S.

1 The default IP address is 192.168.1.1.
2 If you changed the IP address and have forgotten it, you might get the IP address of the 

NBG-318S 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 NBG-318S (it 
depends on the network), so enter this IP address in your Internet browser. 

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

dynamic IP address. See
