2 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick
Start Guide.
3 Make sure your Internet browser does not block pop-up windows and has JavaScript and Java
enabled. See Appendix A on page 199.
4 Make sure your computer is in the same subnet as the NBG6716. (If you know that there are
routers between your computer and the NBG6716, skip this step.)
• If there is a DHCP server on your network, make sure your computer is using a dynamic IP
address. See Section 12.4 on page 118.
• If there is no DHCP server on your network, make sure your computer’s IP address is in the
same subnet as the NBG6716. See Section 12.4 on page 118.
5 Reset the device to its factory defaults, and try to access the NBG6716 with the default IP address.
See Section 1.5 on page 17.
6 If the problem continues, contact the network administrator or vendor, or try one of the advanced
suggestions.
Advanced Suggestions
• Try to access the NBG6716 using another service, such as Telnet. If you can access the
NBG6716, check the remote management settings and firewall rules to find out why the
NBG6716 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 NBG6716.
1 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.
2 This can happen when you fail to log out properly from your last session. Try logging in again after
5 minutes.
3 Disconnect and re-connect the power adaptor or cord to the NBG6716.
4 If this does not work, you have to reset the device to its factory defaults. See Section 24.5 on page
195.
