Chapter 2: Planning Your Wireless Network
Network Topology
A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each
computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same
frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the
same wireless network.
Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.
Choosing between these two modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the
Wireless-G Broadband Router, which serves as the main point of communications in a 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.
If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless-
equipped computers is limited by the distance and interference directly between them.
Network Layout
The Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g
products. Now, products using these standards can communicate with each other.
infrastructure: a wireless network that is bridged
to a wired network via an access point.
ssid (service set identifier): your wireless network’s name.
ad-hoc: a group of wireless devices
communicating directly to each other (peer-to-
peer) without the use of an access point.

The Front Panel
The Router’s SecureEasySetup button (the Cisco logo) and LEDs are located on the front panel.
(Cisco logo) Orange/White. The Cisco logo is the Router’s SecureEasySetup button. It lights up and will stay
orange when the Router is powered on. The color orange indicates that the Router is not using
the SecureEasySetup feature, while the color white indicates that the Router is using the
SecureEasySetup feature. When the Router enters SecureEasySetup mode, the Cisco logo will
turn white and start flashing. After the Router has generated the SSID and WPA-PSK (also
called WPA-Personal) key, the Cisco logo will stop flashing and stay white.
To clear the SSID and WPA-PSK key, press and hold down the Cisco logo for five seconds. The
Cisco logo will flash slowly as the Router resets itself. The Cisco logo will turn orange to
indicate a successful reset.
Power Green. The Power LED lights up and will stay on while the Router is powered on. When the
Router goes through its self-diagnostic mode during every boot-up, this LED will flash. When
the diagnostic is complete, the LED will be solidly lit.
DMZ Green. The DMZ LED indicates when the DMZ function is being used. This LED will remain lit
as long as DMZ is enabled.
WLAN Green. The WLAN LED lights up whenever there is a successful wireless connection. If the LED
is flashing, the Router is actively sending or receiving data over the network.
1, 2, 3, 4 Green. These numbered LEDs, corresponding with the numbered ports on the Router’s back
panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected
to a device through that port. A flashing LED indicates network activity over that port.
Internet Green. The Internet LED lights up when there is a connection made through the Internet port.

Before you install the Router, you must change the default IP address of the other router. This is mandatory
because both routers may be set to the same IP address by default. If you do not change the other router’s default
IP address, then you may not be able to set up the Router.
First, make sure the Router is NOT connected to your network. Then follow these instructions:
1. To access the other router’s Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the
other router’s default IP address, 192.168.1.1, in the Address field. Then press Enter.
2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the
password you have set (the default password is admin). Then click the OK button.
3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called
Local IP Address, which is set to 192.168.1.1. Change this to 192.168.2.1.
4. Click the Save Settings button to save your change, and then exit the Web-based Utility.
5. Power down your network devices. Now you will begin the hardware installation of Router.
6. Locate an optimum location for the Router. The best place for the Router is usually at the center of your
wireless network, with line of sight to all of your mobile stations.
7. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless
network. Normally, the higher you place the antenna, the better the performance will be.
8. Connect a standard Ethernet network cable to the Router’s Internet port. Then, connect the other end of the
Ethernet cable to one of the numbered Ethernet ports on your other router.
