CHAPTER 1

Getting to Know Your NBG420N

This chapter introduces the main features and applications of the NBG420N.

1.1 Overview

The NBG420N acts as either an access point (AP) or a secure broadband router for all data

passing between the Internet and your local network. In both AP and Router Mode you can

set up a wireless network with other IEEE 802.11b/g/n compatible devices. In Router Mode a

number of services such as a firewall, IPSec VPN and content filtering are also available. You

can use media bandwidth management to efficiently manage traffic on your network.

Bandwidth management features allow you to prioritize time-sensitive or highly important

applications such as Voice over the Internet (VoIP).

The NBG420N also uses MIMO (Multiple-In, Multiple-Out) antenna technology to deliver

high-speed wireless networking.

1.2 Router Mode

Select Router Mode if you need to route traffic between your network and another network

such as the Internet, and require important network services such as a firewall or bandwidth

management.

The following figure shows computers in a WLAN connecting to the NBG420N (A), which
