26.2 NBG420N Access and Login

I don’t know the IP address of my NBG420N.

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

NBG420N 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 NBG420N (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 NBG420N’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.

3 If your NBG420N 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.

4 Reset your NBG420N to change all settings back to their default. This means your

current settings are lost. See

Section 26.4 on page 269

in the Troubleshooting for

information on resetting your NBG420N.

I forgot the password.

1 The default password is 1234.
