Chapter 1
Getting To Know Your BR02G
Overview
Thank you for purchasing the GN-BR02G 2.4GHz Wireless Router. Providing
transmission speeds of up to 108Mbps, the GN-BR02G allows users to share
network resources, retrieve emails, download large files, conduct a video
conference, and distribute or display digital photos, videos or MP3 files. The
BR02G is the ideal networking device for you to share a broadband connection
in your home or office. The GN-BR02G gives you a simple, cost-effective
wireless networking solution.
The BR02G offers the newest, strongest, most advanced security features
available today. Unlike most other wireless routers, the BR02G offers
advanced features such as SmartDHCP (the ability to assign IP addresses to
other network devices while still using DHCP), a user editable routing table,
Dynamic DNS mapping (allowing you to host a website on your dynamic DSL
account), and more. Advanced security features such as WPA (Wi-Fi
Protected Access) and 802.1x safeguard your privacy on-line, while URL
blocking keeps kids safe from explicit websites.
Like all 802.11g wireless products, the BR02G is fully backwards compatible
with 802.11b products. This means that you don’t need to change your entire
network to maintain connectivity.

Chapter 2
Wireless Networking
A wireless local area network (or Wi-Fi for short) is exactly like a regular local
area network (LAN), except that each computer in the wireless network uses a
wireless device to connect to the network. Computers in a wireless network
share the same frequency channel and SSID, which is an identification name
shared by the wireless devices belonging to the same wireless network.
The Router transmits data to PCs equipped with wireless network adapters,
which can roam within a certain radial range of the Router. You can arrange the
Router and multiple access points to work in succession to extend the roaming
range, and you can set up your wireless network to communicate with your
Ethernet hardware as well. The big advantage of Wi-Fi is its simplicity. You can
connect computers anywhere in your home or office without the need for wires.
The computers connect to the network using radio signals, and computers can
be up to 100 feet or so apart.
Wireless Network
Layout
The BR02G High-speed
wireless Router has been
specifically designed for use
with both your 802.11b and
802.11g products, and retains
full backward compatibility.
After you have finished
setting up your GN-BR02G
High-speed Wireless Router,
your home network will be
similar to the diagram shown
at the right.
