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 175. 4 Make sure your computer is in the same subnet as the NBG5715. (If you know that there are routers between your computer and the NBG5715, skip this step.) • If there is a DHCP server on your network, make sure your computer is using a dynamic IP address. See Section 13.2 on page 95. • If there is no DHCP server on your network, make sure your computer's IP address is in the same subnet as the NBG5715. See Appendix B on page 186. 5 Reset the device to its factory defaults, and try to access the NBG5715 with the default IP address. See Chapter 22 on page 163. 6 If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions. Advanced Suggestions • Try to access the NBG5715 using another service, such as Telnet. If you can access the NBG5715, check the remote management settings and firewall rules to find out why the NBG5715 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 NBG5715. 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 You cannot log in to the Web Configurator while someone is using Telnet to access the NBG5715. Log out of the NBG5715 in the other session, or ask the person who is logged in to log out. 3 This can happen when you fail to log out properly from your last session. Try logging in again after 5 minutes. 4 Disconnect and re-connect the power adaptor or cord to the NBG5715. 5 If this does not work, you have to reset the device to its factory defaults.
