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

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.

ARP Table Tab
The ARP Table displays the associated MAC address and IP address
pairs of your local network devices. In the example below, only the
BR02G Router is in the ARP Table.
DHCP Lease Table Tab
The DHCP server "leases" out address for specific times (Time To Live)
to the various hosts. If a host does not use a given address for some
period of time, that IP address can then be assigned to another machine.
When assignments are made or changed, the DHCP server must
update the information in the DNS server. The BR02G DHCP Lease
Table displays the associated IP/MAC assignment and Time To Lease.

UPnP Port Mapping Table
The UPnP specification is based on TCP/IP and Internet protocols that
let devices communicate with each other - UPnP technology doesn't rely
on specific device drivers, using instead these standard protocols. UPnP
devices can automatically configure network addressing, announce their
presence on a network subnet, and permit the exchange of device and
service descriptions. The UPnP Port Mapping Table displays the
GN-BR02G port mapping and UPnP packet request details.

The Network Configuration Screen
The Network Configuration screen consists of three areas: LAN
Configuration, WAN Configuration and WAN settings.
The LAN Configuration Tab
LAN Configuration
Allows you to modify the LAN parameters, and if you want to enable DHCP
automatic IP address
assignments, you can enable it here, and specify a Start and End address for
the IP range.
DHCP Option
The DHCP server "leases" out address for specific times (Time To Live) to the
various hosts. If a host does not use a given address for some period of time,
that IP address can then be assigned to another machine. When assignments
are made or changed, the DHCP server must update the information in the
DNS server. The AirCruiser G DHCP Lease Table displays the associated
IP/MAC assignment and Time To Lease.
Force IP-MAC Mapping
Allows you to manually assign a specific IP address to a specific network
device (MAC address) on the network. This will be updated in the ARP table
automatically.
17
GN-BR02G 2.4GHz Wireless Broadband Router
The WAN Configuration Tab
The BR02G has many advanced WAN configuration features. As a special
redundant feature, you can configure up to 4 WAN connections and each ma y
have its own connection type (PPPoE, PPPoE Unnumber, Dynamic IP address,
Static IP address) and other properties. The device can automatically attempt
to connect to these in order if your primary connection fails.
Click the Edit button to the right of the ISP that you wish to modify. A screen
will appear allowing you to change the Internet connection type. (see below)
Click the Next button to continue with modifications.
18
GN-BR02G 2.4GHz Wireless Broadband Router
Depending on the WAN type you select, the corresponding WAN setup screen
will appear next.
WAN Configuration Tab – Dynamic IP Address
Your Internet Service Provider will supply you with the following account
information you will need:
19
GN-BR02G 2.4GHz Wireless Broadband Router
• ISP Name
• Host Name
• Gateway
• DNS1 and DS2 Address
• DNS Domain Name
Enter the information provided by your ISP in the spaces provided.
MTU (Maximum Transmission Unit)
The largest packet unit is sent from your computer to the network. Any
message larger than MTU will be divided into smaller packets before being sent.
You should keep the default setting (1500). Setting MTU size is largely a
process of trial-and-error: If you suspect your MTU setting is causing a
connection problem, start with the maximum value of 1500, and then
reduce the size down to 1400 until the problem goes away.
NAT Setup
The Network Address Translation (NAT) is a standard that allows multiple
computers on a private network to share a single IP address.
Universal Plug and Play (UPnP)
and technologies, such as TCP/IP, HTTP, and XML, that allows devices on a
network to automatically connect with other devices.
UPnP Delete Time
Select the duration that UPnP will be active. Since allowing this may present a
security risk, the default setting is 0.
If the WAN IP address and LAN IP address obtained from DHCP
server are from the same subnet, the LAN IP address will
automatically change to another subnet and reboot the router.
