Wireless-G Router for Mobile Broadband
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Router for Mobile Broadband The Wireless-G Router for
Mobile Broadband will allow you to network wirelessly better than ever, sharing Internet access, files and fun,
easily and securely.
How does the Wireless-G Router for Mobile Broadband do all of this? A router is a device that allows access to an
Internet connection over a network. With the Wireless-G Router for Mobile Broadband, you can access the
Internet through either your mobile broadband service (requires a mobile broadband data card, available
separately), or you can use a cable or DSL modem for broadband service. Plus, this access can be shared over
the four switched ports or via the wireless broadcast at up to 54Mbps for Wireless-G or up to 11Mbps for
Wireless-B.
Use the WPA or WPA2 standard to secure your wireless network while the whole network is protected through a
Stateful Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. Run the Setup Wizard
and it will guide you through the steps. You can also access the Router’s features through the easy-to-use,
browser-based utility.
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.
PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wireless Local Area Network. The Wireless-G Router for Mobile Broadband bridges wireless networks
of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.
With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet
access—and even play games. All the while, the Wireless-G Router for Mobile Broadband protects your networks
from unauthorized and unwelcome users.
lan (local area network): The computers and
networking products that make up the network in
your home or office.
nat (network address translation): NAT technology
translates IP addresses of a local area network to a
different IP address for the Internet.
wpa (wi-fi protected access): a wireless security
protocol using TKIP (Temporal Key Integrity Protocol)
encryption, which can be used in conjunction with a
RADIUS server.
spi (stateful packet inspection) firewall: a technology
that inspects incoming packets of information before
allowing them to enter the network.
firewall: Security measures that protect the
resources of a local network from intruders.
wpa2 (wi-fi protected access2: a wireless security protocol
using TKIP (Temporal Key Integrity Protocol) encryption and
AES (Advanced Encryption System) with dynamic encryption
keys, which can be used in conjunction with a RADIUS server.

Network Topology
Wireless-G Router for Mobile Broadband
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 Router for Mobile Broadband, 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 Router for Mobile Broadband has been specifically designed for use with both your 802.11b and
802.11g products. It is compatible with all 802.11g and 802.11b adapters, such as the notebook adapters for your
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 other Router is 192.168.1.1. If so, there will be an IP address conflict with the new Router. Follow the
instructions below to change the default IP address of the existing Router to 192.168.2.1.
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 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. Attach the antenna and fix its direction. 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.
Figure 4-6: Diagram for Connection to Another Router
NOTE: Steps 1-4 are instructions for a typical Linksys router; however, if you are using
a non-Linksys router, refer to the other router’s documentation for instructions on how
to change its local IP address to 192.168.2.1.

Wireless-G Router for Mobile Broadband
The Wireless Tab - Advanced Wireless Settings
This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an
expert administrator as incorrect settings can reduce wireless performance.
Advanced Wireless
Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication
to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key for
authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication.
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so
they know which rates will be used. The Router will also advertise that it will automatically select the best rate
for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless
technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of
data transmission. If you want to specify the Router’s rate of data transmission, configure the Transmission Rate
setting.
Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can select Auto to have the Router
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Router and a wireless client. The default value is Auto.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having
severe problems with your Wireless-G products not being able to transmit to the Router in an environment with
heavy 802.11b traffic. This function boosts the Router’s ability to catch all Wireless-G transmissions but will
severely decrease performance.
Frame Burst. Enabling this option should provide your network with greater performance, depending on the
manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Disable.
Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize
the wireless network.
DTIM Interval. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it
Figure 8-29: Wireless Tab - Advanced Wireless Settings
69
Chapter 8: Configuring the Wireless-G Router for Mobile Broadband
The Wireless Tab - Advanced Wireless Settings
Wireless-G Router for Mobile Broadband
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 1.
Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into
multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor
reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value
of 2347.
AP Isolation. This isolates all wireless clients and wireless devices on your network from each other. Wireless
devices will be able to communicate with the Router but not with each other. To use this function, select On. AP
Isolation is Off by default.
