V I forgot the IP address for the NBG318S.
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
NBG318S 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 NBG318S (it
depends on the network), so enter this IP address in your Internet browser.

26.4 on page 233.

the Quick Start Guide.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts
and Java enabled. See
Appendix B on page 245.
4 Make sure your computer is in the same subnet as the NBG318S. (If you know that there
are routers between your computer and the NBG318S, skip this step.)
• If there is a DHCP server on your network, make sure your computer is using a
dynamic IP address. See
Section 9.3 on page 118. Your NBG318S is a DHCP server
by default.
• If there is no DHCP server on your network, make sure your computer’s IP address is
in the same subnet as the NBG318S. See
Section 9.3 on page 118.
