14.3 NBG7815 Access and Login
I don't know the IP address of my NBG7815.
• The default IP address of the NBG7815 in Standard Mode is 192.168.123.1. If the NBG7815 obtains a
WAN IP address in the same subnet as the LAN IP address 192.168.123.1, the default LAN IP address will
be changed to 10.0.0.1 automatically. See
The default IP address of the NBG7815 in Bridge Mode is 192.168.123.2.
• If you changed the IP address and have forgotten it, you might get the IP address of the NBG7815 in
Standard 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 NBG7815 (it depends on the network), so enter this IP
address in your Internet browser.
• If your NBG7815 in Bridge Mode is a DHCP client, you can find your IP address from the DHCP server.
This information is only available from the DHCP server which allocates IP addresses on your network.
Find this information directly from the DHCP server or contact your system administrator for more
information.
• Reset your NBG7815 to change all settings back to their default. This means your current settings are
lost. See
Section 14.5 on page 147
I cannot see or access the Login screen in the Web Configurator.
• Make sure you are using the correct IP address.

WAN IP address in the same subnet as the LAN IP address 192.168.123.1, the default LAN IP address will
