Advanced Suggestions
• Try to access the NBG6604 using another service, such as Telnet. If you can access the NBG6604,
check the remote management settings and firewall rules to find out why the NBG6604 does not
respond to HTTP.
• If your computer is connected to the WAN port or is connected wirelessly, use a computer that is
connected to a LAN/ETHERNET port.
I can see the Login screen, but I cannot log in to the NBG6604.
Make sure you have entered the password correctly. The default password is 1234. This field is case-

2
minutes.
