24.2NBG-417N Access and Login

I don’t know the IP address of my NBG-417N.

1The default IP address is 192.168.1.1.

2If you changed the IP address and have forgotten it, you might get the IP address of the NBG-417N 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-417N (it depends on the network), so enter this IP address in your Internet browser.Set your device to Router Mode, login (see the Quick Start Guide for instructions) and go to the Device Information table in the Status screen. Your NBG-417N’s IP address is available in the Device Information table.

•If the DHCP setting under LAN information is None, your device has a fixed IP address.

•If the DHCP setting under LAN information is Client, then your device receives an IP address from a DHCP server on the network.

3If your NBG-417N 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.

4Reset your NBG-417N to change all settings back to their default. This means your current settings are lost. See Section 24.4 on page 195 in the Troubleshooting for information on resetting your NBG-417N.

I forgot the password.

1The default password is 1234.
