Appendix A: Troubleshooting
Frequently Asked Questions
38
Wireless A/G Game Adapter
What is roaming?
Roaming is the ability of a portable computer to communicate continuously while it and its user are moving freely
throughout an area greater than that covered by a single access point. Before using the roaming function, the
user must make sure that the workstation is set to the same channel number used by the 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 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 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 access
point and the distance of each access point to the wired backbone. Based on that information, the node next
selects the right 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 access point or whether it should seek a new one. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.
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 SpreadAppendix A: Troubleshooting
Frequently Asked Questions
ism band: radio bandwidth utilized in wireless transmissions.
spread spectrum: wideband radio frequency technique
used for more reliable and secure data transmission.
dsss: Frequency transmission with a redundant bit
pattern resulting in a lower probability of information
being lost in transit.
39
Wireless A/G Game Adapter
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?
WLAN features 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, WLAN offers the encryption
function (WEP) to enhance security and access control.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
IEEE 802.11 standard. For more information, refer to “Appendix B: Wireless Security.”

Wireless A/G Game Adapter
Appendix B: Wireless Security
Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
Linksys products provide several network security features, but they require specific action on your part for
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take (as shown in this User Guide) (at least steps 1
through 5 should be followed):
1. Change the default SSID.
2. Disable SSID Broadcast.
3. Change the default password for the Administrator account.
4. Enable MAC Address Filtering.
5. Change the SSID periodically.
Note: Some of these security features are
available only through the network router or
access point. Refer to the router or access
point’s documentation for more information.
6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
your network performance.
7. Change the WEP encryption keys periodically.
To ensure network security, steps one through five should be followed, at least.
Security Threats Facing Wireless Networks
Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
Change the administrator’s password regularly. With every wireless networking device you use, keep in mind
that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only
person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can
change those settings. So, make it harder for a hacker to get that information. Change the administrator’s
password regularly.
Appendix B: Wireless Security
Security Precautions
41
Wireless A/G Game Adapter
SSID. There are several things to keep in mind about the SSID:
1. Disable Broadcast
2. Make it unique
3. Change it often
Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
the SSID.
Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
Hackers know these defaults and can check these against your network. Change your SSID to something unique
and not something related to your company or the networking products you use.
Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
start from the beginning in trying to break in.
MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
a random MAC Address.
WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security
concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job
more difficult.
There are several ways that WEP can be maximized:
1. Use the highest level of encryption possible
2. Use “Shared Key” authentication
3. Change your WEP key regularly
Important: Always remember that each
device in your wireless network MUST use
the same encryption method and encryption
key or your wireless network will not function
properly.
WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are
available: Pre-Shared Key and RADIUS. Pre-Shared Key gives you a choice of two encryption methods: TKIP
(Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message
Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes
a symmetric 128-Bit block data encryption. RADIUS (Remote Authentication Dial-In User Service) utilizes a
RADIUS server for authentication and the use of dynamic TKIP, AES, or WEP.
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
42
Wireless A/G Game Adapter
WPA Pre-Shared Key. If you do not have a RADIUS server, select the type of algorithm, TKIP or AES, enter a
password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time between
0 and 99,999 seconds, which instructs the Router or other device how often it should change the encryption
keys.
WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
server is connected to the Router or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter
the RADIUS server’s IP Address and port number, along with a key shared between the device and the server.
Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption
keys.
RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
connected to the Router or other device.) First, enter the RADIUS server’s IP Address and port number, along
with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption,
and either generate a WEP key through the Passphrase or enter the WEP key manually.
Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting
sensitive data over your network, encryption should be used.
These security recommendations should help keep your mind at ease while you are enjoying the most flexible
and convenient technology Linksys has to offer.
