23.2 NBG-418N v2 Access and Login
I don’t know the IP address of my NBG-418N v2.
1 The default web address in Router Mode is http://myrouter.
2 The default IP address in router mode is 192.168.1.1 and in non-router mode is 192.168.1.2.
3 If you changed the IP address and have forgotten it, you might get the IP address of the NBG-418N
v2 in Router Mode 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 NBG-418N v2 (it depends on the
network), so enter this IP address in your Internet browser.
4 Reset your NBG-418N v2 to change all settings back to their default. This means your current
settings are lost. See Section 23.4 on page 154 in the Troubleshooting for information on
resetting your NBG-418N v2.
I forgot the username and password.
1 The default username is admin and default password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See Section 23.4 on page
154.
I cannot see or access the Login screen in the Web Configurator.
1 Make sure you are using the correct IP address.
• The default IP address is 192.168.1.1 (router mode).
• If you changed the IP address, use the new IP address.
• If you changed the IP address and have forgotten it, see the troubleshooting suggestions for I
don’t know the IP address of my NBG-418N v2.
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 B on page 166.
4 Make sure your computer is in the same subnet as the NBG-418N v2. (If you know that there are
routers between your computer and the NBG-418N v2, skip this step.)
• If there is a DHCP server on your network, make sure your computer is using a dynamic IP
address.
