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

Auto-IP Change on page 80

for more information.


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

in the

Troubleshooting

for information on resetting your NBG7815.

I cannot see or access the

Login

screen in the Web Configurator.

•

Make sure you are using the correct IP address.

•


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

I don’t

know the IP address of my NBG7815.

•

Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick

Start Guide.

•

Make sure your Internet browser does not block pop-up windows and has JavaScript and Java

enabled. See

Appendix B on page 156


•

Make sure your computer is in the same subnet as the NBG7815. (If you know that there are routers

between your computer and the NBG7815, skip this step.)

•

If there is a DHCP server on your network, make sure your computer is using a dynamic IP address. See


.

•

If there is no DHCP server on your network, make sure your computer’s IP address is in the same subnet

as the NBG7815. See


.

•

Reset the device to its factory defaults, and try to access the NBG7815 with the default IP address.

See


.

•

If the problem continues, contact the network administrator or vendor, or try one of the advanced

suggestions.
