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

You cannot log in to the Web Configurator while someone is using Telnet to access 
the NBG-460N. Log out of the NBG-460N in the other session, or ask the person 
who is logged in to log out. 

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-460N. 

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