System Operation Mode Overview
The
Sys OP Mode
(System Operation Mode) function lets you configure your NBG6716 as a router
or access point. You can choose between
Router Mode
, and
Access Point Mode
depending on
your network topology and the features you require from your device.
The following describes the device modes available in your NBG6716.
Router
A router connects your local network with another network, such as the Internet. The router has
two IP addresses, the LAN IP address and the WAN IP address.

Access Point

connect to the Internet, another device, such as a router, is required.

NBG6716 Access and Login
I don’t know the IP address of my NBG6716.

. The default IP address of
the NBG6716 in

If you changed the IP address and have forgotten it, you might get the IP address of the NBG6716
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

address of the
Default Gateway
might be the IP address of the NBG6716 (it depends on the
network), so enter this IP address in your Internet browser.

If your NBG6716 in
Access Point 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 NBG6716 to change all settings back to their default. This means your current settings
will be lost. See
Section 24.5 on page 178
