Overview
The NBG420N is an IEEE 802.11b/g/n wireless broadband router or access point (AP). As
a router, the NBG420N directs traffic between your wireless network and another network
such as the Internet as shown below, providing services such as content filtering,
bandwidth management and a firewall.
This Quick Start Guide shows you how to do the following with your NBG420N in router
mode:
1Connecting Your Hardware
2Accessing the Web Configurator
3Connecting to the Internet with the Wizard
4Set Up a Wireless Network Manually or with WPS
See your User’s Guide on the CD in the package on how to set up the NBG420N as an AP
and for more information on all features.
To read the User’s Guide insert the CD that came in the box into your CD-ROM drive. A
screen should pop up. Navigate to the User’s Guide from this screen. If a screen does not
pop up, open Windows Explorer (click My Computer), click on the CD-ROM drive (usually
