rThe Wireless-G Ethernet Bridge
The versatile Wireless-G Ethernet Bridge can make any wired Ethernetequipped device a part of your wireless network. At home, use the Bridge to
connect game consoles, set-top boxes, or computers to your Wireless-G network and its shared high-speed Internet connection. In the office, convert your
Ethernet-wired printer, scanner, camera, notebook or desktop into a wireless
networked device.
It’s completely driver-free, so it works on any platform and under any operating system! Since there are no drivers to load, setup is a snap—configure the
network settings through your PC’s web browser, then plug it into your device
and go. And physical installation is simplified by support for Power over
Ethernet. With an optional PoE Adapter, you can mount the Bridge wherever
you want—power and data are both supplied through the Category 5 Ethernet
cable.
You can also use the Wireless-G Ethernet Bridge as a kind of “cable-less cable”
to connect remote areas together. Maybe Shipping is all the way across the
warehouse from Receiving. Or maybe you want to set up a home office in your
detached garage. With a Wireless-G Ethernet Bridge in the garage, and another one (or a Wireless-G Access Point) in the house, you’re connected—no digging trenches, and no overhead wires.
Let the Wireless-G Ethernet Bridge from Linksys open up exciting new possibilities for your wireless network.

Chapter 3: 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 for wireless devices.
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 an access point, which serves as the
main point of communications in a wireless network (see Figure 3-1). Access
points transmit data to PCs equipped with wireless network cards, which can
roam within a certain radial range of the access point. Multiple access points
can be arranged to work in succession to extend the roaming range, and can be
set up to communicate with your Ethernet hardware as well.
Figure 3-1
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
an access point. The drawback of this mode is that in Ad-Hoc mode, wirelessequipped 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.
Instant Wireless® Series
Figure 3-2 shows a typical scenario
of four Wireless-G Ethernet Bridges
in ad-hoc mode. Figure 3-3 shows a
typical wireless bridging scenario
using two Wireless-G Ethernet
Bridges. Each wireless network is
connected to a Wireless-G Ethernet
Bridge through a switch. A separate
notebook computer is equipped with
a wireless PC card and can communicate with both wireless networks as
long as it has the same SSID and
channel as both wireless networks.

An acronym for Wired Equivalent Privacy, WEP is an encryption method
used to protect your wireless data communications. WEP uses 64-bit or
128-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each device
in a network must use an identical WEP key. Higher encryption levels offer
higher levels of security, but due to the complexity of the encryption, they
may decrease network performance.

Advanced
Wireless
Use the Advanced Settings screen to customize advanced wireless settings and
clone a MAC address onto the Bridge.
•
Transmission Rate - The default setting is Auto. The range is from 1 to
54Mbps.
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 keep the default setting, Auto, to have the Bridge automatically use
the fastest possible data rate and enable the Auto-Fallback feature. AutoFallback will negotiate the best possible connection speed between the
Bridge and another wireless-equipped device.
•
Authentication Type - The default setting is Auto. The choices are Auto,
Open, and Shared.
This setting allows the Bridge to authenticate communication with the wireless devices in your network. With the Shared Key setting, all wireless
devices must have the same WEP keys so that the Bridge and the client can
authenticate each other and start transmitting data. With the Open System
setting, any device can join a network without performing any security
check. Using the Auto setting, the Bridge will automatically detect whether
a wireless device is set to Shared Key or Open System, and then transmit
data using the appropriate authentication type.
•
RTS Threshold - This value should remain at its default setting of 2347.
The range is 0-2347 bytes. Should you encounter inconsistent data flow,
only minor modifications are 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.
•
Fragmentation Threshold - This value should remain at its default setting
of 2346. The range is 256-2346 bytes. It 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 modifications of this value are recommended.

5. The Web-based Utility won’t open.
Make sure that you have a network adapter installed on the PC so you can
use the Web-based Utility.
Common Problems and Solutions
This section provides solutions to potential problems regarding the installation and
operation of the Wireless-G Ethernet Bridge. If you can’t find an answer here,
check the Linksys website at www.linksys.com.
1. I can’t connect to the access point.
Open the Web-based Utility. On the Setup tab, perform the following steps:
• Verify that the operating mode is set to Infrastructure mode.
• Make sure that the SSID is the same as the SSID of the access point.
• On the WEP Encryption screen, make sure that all of the WEP settings are
the same as the WEP settings of the access point.
2. I don’t know how to change the Bridge’s IP address.
You have two ways to change the Bridge’s IP address.
• Open the Web-based Utility. On the Setup screen, click the Static IP
Address radio button, and change the IP address there.
• If you encounter problems, power the Bridge off and on again, or push the
Reset button. Then try to change the IP address again.
3. The Bridge-enabled PC won’t communicate with a wireless-enabled PC or
printer.
Perform the following steps:
• Check that the wireless-enabled PC or printer is on the same wireless network as the PC using the Bridge.
• Make sure that the SSID and network mode are the same for all devices
connected to the same wireless network.
• If the wireless LAN settings are okay, make sure that all the devices are
on the same IP network.
4. The Web-based Utility doesn’t detect the Bridge.
Make sure that the Ethernet cable is properly connected and that the
Ethernet LED is lit. If the LED is not lit, change the position of the X-II slide
switch on the Bridge’s rear panel. Use the X setting if you are connecting the
Bridge to a network adapter. Use the II setting if you are connecting the
Bridge to a hub or switch. If you still do not have an active connection, then
change the position of the X-II switch again.
32
6. The Web-based Utility does not recognize my password.
The password is case-sensitive. Make sure you are using the correct case(s)
when entering the password.
If you forget your password, you can push the Bridge’s Reset button. This
will reset the password to the default setting; however, all other Bridge settings will be reset to the factory defaults as well. To use the default setting,
enter admin in the Password field.
7. After I make changes through the Web-based Utility, the new settings aren’t displayed on-screen.
Click the Refresh button of your web browser. If the new settings aren’t displayed, then unplug the power adapter from the Bridge. Plug the power
adapter back in, and then click the Refresh button again.
Frequently Asked Questions
What is the IEEE 802.11b standard?
It is one of the IEEE standards for wireless networks. The 802.11b standard
allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The
802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11 functions:
•
CSMA/CA plus Acknowledge protocol
•
Multi-Channel Roaming
•
Automatic Rate Selection
•
RTS/CTS feature
•
Fragmentation
•
Power Management
Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over
a network. Consult the application’s user guide to determine if it supports operation over a network.
33
Instant Wireless® Series
Can I play multiplayer games with other users of the wireless network?
Yes, as long as the game supports multiple players over a LAN. Refer to the
game’s user guide for more information.
What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc
wireless network will not communicate with any wired network.
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is
configured to communicate with a wired network through a wireless access
point.
What is roaming?
Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single wireless network access point. Before using the roaming function, the
workstation must make sure that it is the same channel number as the wireless
network access point of the dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a
number of different functions. Each node and wireless network access point,
for example, must always acknowledge receipt of each message. Each node
must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF
networking technology that links wireless network access points and nodes. In
such a system, the user’s end node undertakes a search for the best possible
access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each wireless network access point and the distance of each wireless network access point to the
wired backbone. Based on that information, the node next selects the right
wireless network access point and registers its address. Communications
between end node and host computer can then be transmitted up and down the
backbone.
As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in touch with the original wireless network
access point or whether it should seek a new one. When a node no longer
receives acknowledgment from its original wireless network access point, it
undertakes a new search. Upon finding a new wireless network access point, it
then re-registers, and the communication process continues.

Wireless-G Ethernet Bridge
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the ISM (Industrial, Scientific and Medical) band.
Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient
high speed wireless capabilities in the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability,
integrity, and security. In other words, more bandwidth is consumed than in the
case of narrowband transmission, but the trade-off produces a signal that is, in
effect, louder and thus easier to detect, provided that the receiver knows the
parameters of the spread-spectrum signal being broadcast. If a receiver is not
tuned to the right frequency, a spread-spectrum signal looks like background
noise. There are two main alternatives, Direct Sequence Spread Spectrum
(DSSS) and Frequency Hopping Spread Spectrum (FHSS).
What is DSSS? What is FHSS? And what are their differences?
Frequency Hopping Spread Spectrum (FHSS) uses a narrowband carrier that
changes frequency in a pattern that is known to both transmitter and receiver.
Properly synchronized, the net effect is to maintain a single logical channel. To
an unintended receiver, FHSS appears to be short-duration impulse noise.
Direct Sequence Spread Spectrum (DSSS) generates a redundant bit pattern for
each bit to be transmitted. This bit pattern is called a chip (or chipping code).
The longer the chip, the greater the probability that the original data can be
recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data
without the need for retransmission. To an unintended receiver, DSSS appears
as low power wideband noise and is rejected (ignored) by most narrowband
receivers.
Would the information be intercepted while transmitting on air?
Instant Wireless products feature two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the
inherent security feature of scrambling. On the software side, Instant Wireless
products offer the encryption function (WEP) to enhance security and access
control. Users can set it up depending upon their needs.
35
Instant Wireless® Series
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40/64
bit shared key algorithm, as described in the IEEE 802.11 standard.
Can Instant Wireless products support file and printer sharing?
Instant Wireless products perform the same function as LAN products.
Therefore, Instant Wireless products can work with NetWare, Windows
NT/2000, or other LAN operating systems to support printer or file sharing.
Wireless-G Ethernet Bridge
Appendix B: Glossary
802.11b - One of the IEEE standards for wireless networking hardware.
Products that adhere to a specific IEEE standard will work with each other,
even if they are manufactured by different companies. The 802.11b standard
specifies a maximum data transfer rate of 11Mbps, an operating frequency of
2.4GHz, and WEP encryption for security. 802.11b networks are also referred
to as Wi-Fi networks.
802.11g - A proposed, but as yet unratified extension of the IEEE 802.11 standard for wireless networking hardware. The draft 802.11g specifications used
by Linksys specify a maximum data transfer rate of 54Mbps using OFDM
modulation, an operating frequency of 2.4GHz, backward compatibility with
IEEE 802.11b devices, and WEP encryption for security.
Ad-hoc Network - An ad-hoc network is a group of computers, each with a
wireless adapter, connected as an independent 802.11 wireless LAN. Ad-hoc
wireless computers operate on a peer-to-peer basis, communicating directly
with each other without the use of an access point. Ad-hoc mode is also
referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode, and is useful at a departmental scale or SOHO operation.
Default Gateway - The router used to forward all traffic that is not addressed
to a station within the local subnet.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators centrally manage and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet's set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DHCP uses the concept of a “lease” or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It’s espe-
36
37
Instant Wireless® Series
cially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
DNS - The Domain Name System (DNS) is the way that Internet domain
names are located and translated into Internet Protocol (IP) addresses. A
domain name is a meaningful and easy-to-remember “handle” for an Internet
address.
DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit
pattern for all transmitted data. This bit pattern is called a chip (or chipping
code). Even if one or more bits in the chip are damaged during transmission,
statistical techniques embedded in the receiver can recover the original data
without the need for retransmission. To an unintended receiver, DSSS appears
as low power wideband noise and is rejected (ignored) by most narrowband
receivers. However, to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference
is inherently rejected (ignored).
Dynamic IP Address - An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
serve multiple users, such as servers and printers, are usually assigned static IP
addresses.
FHSS (Frequency Hopping Spread Spectrum) - FHSS continuously changes
(hops) the carrier frequency of a conventional carrier several times per second
according to a pseudo-random set of channels. Because a fixed frequency is not
used, and only the transmitter and receiver know the hop patterns, interception
of FHSS is extremely difficult.
Firmware - Code that is written onto read-only memory (ROM) or programmable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
describes itself as “the world's largest technical professional society—promoting the development and application of electrotechnology and allied sciences
for the benefit of humanity, the advancement of the profession, and the wellbeing of our members.”
38
Wireless-G Ethernet Bridge
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and has several large societies in special areas, such as the
IEEE Computer Society.
Infrastructure Network - An infrastructure network is a group of computers
or other devices, each with a wireless adapter, connected as an 802.11 wireless
LAN. In infrastructure mode, the wireless devices communicate with each
other and to a wired network by first going through an access point. An infrastructure wireless network connected to a wired network is referred to as a
Basic Service Set (BSS). A set of two or more BSS in a single network is
referred to as an Extended Service Set (ESS). Infrastructure mode is useful at
a corporation scale, or when it is necessary to connect the wired and wireless
networks.
IP Address - In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packets across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more
than one is required) and sends it to the IP address that is obtained by looking
up the domain name in the Uniform Resource Locator you requested or in the
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requester or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONFIG - A utility that provides for querying, defining and managing IP
addresses within a network. A commonly used utility, under Windows NT and
2000, for configuring networks with static IP addresses.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as website
building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
MAC Address - The MAC (Media Access Control) address is a unique number assigned by the manufacturer to any Ethernet networking device, such as a
network adapter, that allows the network to identify it at the hardware level.

mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining, and leaving channels.
Wireless-G Ethernet Bridge
interruption to network connectivity. A typical scenario would be a location
with multiple access points, where users can physically relocate from one area
to another and easily maintain connectivity.
Network Mask - Also known as the “Subnet Mask.”
OFDM - Developed for wireless applications, Orthogonal Frequency Division
Multiplexing (OFDM) technology offers superior performance—increased
data rates and more reliable transmissions—than previous technologies, such as
DSSS. OFDM is a scheme in which numerous signals of different frequencies
are combined to form a single signal for transmission on the medium.
SSID (Service Set IDentifier) - A unique name shared among all points in a
wireless network. The SSID must be identical for each point in the wireless network and is case-sensitive.
OFDM works by breaking one high-speed data stream into a number of lowerspeed data streams, which are then transmitted in parallel. Each lower-speed
stream is used to modulate a subcarrier. Essentially, this creates a multi-carrier
transmission by dividing a wide frequency band or channel into a number of
narrower frequency bands or sub-channels. OFDM is also used for other applications, including powerline networking.
Static IP Address - A permanent IP address that is assigned to a node in a
TCP/IP network.
Passphrase - Used much like a password, a passphrase simplifies the WEP
encryption process by automatically generating the WEP encryption keys for
Linksys products.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the IP (Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. TCP is known as a “connection oriented” protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
PCMCIA - The PCMCIA (Personal Computer Memory Card International
Association) is an industry group organized in 1989 to promote standards for a
credit card-size memory or I/O device that would fit into a personal computer,
usually a notebook or laptop computer.
Ping (Packet INternet Groper) - An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response.
Power over Ethernet (PoE) - A technology that allows a device, such as a
power injector, power hub, or inline power device, to supply data and power to
an Ethernet device using a single Ethernet network cable.
RJ-45 - A connector similar to a telephone connector that holds up to eight
wires, used for connecting Ethernet devices.
Roaming - In an infrastructure mode wireless network, this refers to the ability to move out of one access point's range and into another and transparently
reassociate and reauthenticate to the new access point. This reassociation and
reauthentication should occur without user intervention and ideally without
40
SOHO (Small Office/Home Office) - Refers to any small office or home
office environment.
Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or set of protocols for communications over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of
protocols and not only TCP and IP.
UDP (User Datagram Protocol) - A method (protocol) used along with the IP
(Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. UDP is known as a “connection-less” protocol
due to NOT requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet (as opposed to TCP).
