Keys window.
None
No security (not recommended).
Allow Association to
Mixed Cells
Check this check box if the access point with which the client adapter is
to associate has WEP set to Optional and WEP is enabled on the client
adapter. Otherwise, the client is unable to establish a connection with
the access point.
Check this check box and enter the number of seconds (up to 300) after
which the authentication process times out when trying to find the
domain controller. Entering zero is like unchecking this check box,
which means no time limit is imposed for finding the domain controller.
Note: The authentication process times out whenever the authentication
timer times out or the time for finding the domain controller is reached.
Limit Time for
Finding Domain
Controller To
Group Policy Delay
Specify how much time elapses before the Windows logon process
starts group policy. Group policy is a Windows feature used by
administrators to specify configuration options for groups of users. The
objective is to delay the start of Group Policy until wireless network
authentication occurs. Valid ranges are from 0 to 65535 seconds. The
value that you set goes into effect after you reboot your computer with
this profile set as the active profile.
This drop-down menu is active only if you chose EAP-based
authentication.

Appendix A: FAQ about WLAN
1.
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).
2.
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.
3.
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.
4.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared
key algorithm, as described in the IEEE 802.11 standard.
5.
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.
10
6.
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 access point. Before using the
roaming function, the workstation must make sure that it is the same channel number with the
access point of 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.
