Universal Repeater
: In this mode, the NBG-418N (N) can be an access point and a wireless
client at the same time. Use this mode if there is an existing wireless router or access point in
your network and you want the NBG-418N (N) to wirelessly relay communications from its
wireless clients to the access point.

Universal Repeater
Client Bridge
: Use this mode if there is an existing wireless router or access point (AP) in the
network to which you want to connect your NBG-418N (N) wirelessly. You should know the SSID
and wireless security details of the wireless router or access point to which you want to connect.

Setting your NBG-418N to Router Mode
The NBG-418N is set to wireless router mode by default. If it was changed and now you want to set
it back, do the following procedure.
1
Connect your computer to the LAN port of the NBG-418N.
2
The default LAN IP address of the NBG-418N is 192.168.1.1 in router mode (192.168.1.2 by default
in non-router mode). In router mode, the NBG-418N can assign your computer an IP address, so
you must set your computer to get an IP address automatically (computer factory default) or give it
a fixed IP address in the range between 192.168.1.3 and 192.168.1.254.
3
After you’ve set your computer’s IP address, open a web browser such as Internet Explorer and
type the IP address of the NBG-418N as the web address in your web browser.
4
Log into the Web Configurator. See the
Chapter 2 on page 17
for instructions on how to do this.

Summary: DHCP Table
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the NBG-418N’s LAN as a
DHCP server or disable it. When configured as a server, the NBG-418N provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server on
that network, or else the computer must be manually configured.
Click the
DHCP Table (Details...)
hyperlink in the
Status
screen. Read-only information here
relates to your DHCP status. The DHCP table shows current DHCP client information (including
IP
Address
,
Host
Name
and
MAC Address
) of all network clients using the NBG-418N’s DHCP
server.
