Wireless LAN network defined by IEEE 802.11n/b/g standard committee
could be configured as :
Ad Hoc wireless LAN, or
Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards, this
group of PCs is called a BSS (Basic Service Set). PCs in this group can use
their wireless LAN cards to communicate with each other, but can not
connect to the Internet.
Ad Hoc Wireless Network Infrastructure Wireless Network
The most obvious difference between Infrastructure wireless network
and Ad Hoc wireless network is that the PCs in Infrastructure wireless
network can access the resource in the Internet through Access Point.
Depending on your requirement, you can easily set up your PC’s
network to be a “Ad Hoc” or “Infrastructure” wireless network. Generally
speaking, if in your network, there is an Access Point in it, we recommend
you to set your network as an “Infrastructure”, so it can connect to
the Internet.

To use the WLAN 11n USB Adapter with a computing device, the WLAN 11n USB
Adapter must be equipped with an USB 1.1 or 2.0 Interface. All drivers and supporting
software for the WLAN 11n USB Adapter must be installed and configured first.
Ask your system administrator for the following information, which you may need to
provide during driver installation :
Your Wireless Client Name.
Your Wireless SSID.
Your computer’s unique client name and workgroup name.
For your network account, your user name and password.
Your IP address, gateway address, and subnet mask if you’re not using a DHCP
server.
Any computer on a network is identified by a unique network address. There are two
methods to assign a network address to a computer on a TCP/IP network :
Static IP addressing.
Dynamic IP addressing (DHCP).
In network with static IP addressing, the network administrator manually assigns an IP
address to each computer. Once a static IP address is assigned, a computer uses the
same IP address every time it reboots and logs on to the network. You may manually
change the IP address in the Network Properties dialog box. Network using static
IP address is easy to set up and do not require additional network management
software.
In network with dynamic IP addressing, a DHCP server in the network dynamically
assigns IP addresses to all clients every time they log on to the network. Network
using dynamic IP address requires setting up and running a DHCP Server.

Username and Password window appears. To know more about this option
refer Using PEAP-MSCHAP V2 security.
If you chose TLS Client Certificate from the EAP-FAST Authentication Method
drop-down list and clicked Configure, the Define Certificate window appears.
When configuring EAP-TLS for EAP-FAST, you can check the Authenticate
Server Identity check box to force the system to authenticate the identity of the
server as an added level of security. This option is available only when
configuring EAP-FAST. To know more about this option refer Using EAP-TLS
security.
If you want to force the client adapter to disassociate after you log off so that
another user cannot gain access to the wireless network using your credentials,
check the No Network Connection Unless User is Logged In check box. The
default setting is checked.
Perform one of the following:
If you want to enable automatic PAC provisioning, make sure the Allow
Automatic PAC Provisioning for this Profile check box is checked. A protected
access credentials (PAC) file is obtained automatically as needed (for instance,
when a PAC expires, when the client adapter accesses a different server,
when the EAP-FAST username cannot be matched to a previously provisioned
PAC, etc.). This is the default setting.
If you want to enable manual PAC provisioning, uncheck the Allow Automatic
PAC Provisioning for this Profile check box. This option requires you to choose
a PAC authority or manually import a PAC file.
From the Select one or more PAC Authority to use with this Profile list,
highlight the PAC authorities associated with the network defined by the
profile's SSID. The list contains the names of all the authentication servers
from which you have previously provisioned a PAC.
Click Manage. The Select EAP-FAST PAC window appears.
This window lets you group PAC authorities to facilitate authentication while
roaming. For example, if there are three PAC authorities at a certain site
covering different areas of the site, you can create a group containing these
authorities and select one of them in the PAC list. In this way, if you're roaming
21
around the site, the other authorities in the group will allow you access to the
network.
A group consists of one or more authorities. Each authority may have one or
more PAC files. A PAC authority can belong to only one group.
To create a new group, click New Group. A group consists of one or more
authority servers that the user trusts. To rename the group, right-click the
group and choose Rename. You can also rename the group by clicking it and
typing the new name.
When you create a new group, you can either import a PAC file into it using the
Import button or you can move a PAC from another group to the new group.
To import a PAC, click Import. The PAC Import window appears. Do the
following:
Click Browse and select a PAC file to import. The default location is
C:/Program Files/Atheros.
Click the PAC file (*.pac) so that it appears in the File name box at the bottom
of the window.
Click Open.
If the Enter Password window appears, enter the PAC file password, which
can be obtained from your system administrator, and click OK.
Note: PAC file passwords are optional. The PAC authority determines whether
to issue PAC files that require user-supplied passwords. Nevertheless, all PAC
files (even those without passwords) are encrypted and protected. PAC file
passwords are different from EAP-FAST passwords and need to be entered
only once, at the time a PAC is imported.
If you try to import a PAC file with the same PAC ID as a previously imported
PAC file, you are asked to update the existing PAC. If you click Yes, the
existing PAC is replaced by the new one from the imported file.
If the PAC file was imported successfully, the following message appears:
"EAP-FAST PAC file was imported and is ready for use." Click OK to return to
the PAC Import window.
Click one of these PAC store options to determine where the imported PAC file
will be stored and by whom it will be accessible:
Global - PACs that are stored in the global PAC store can be accessed and
used by any user at any logon stage. Global PACs are available before or
22
during logon or after the user is logged off if the profile is not configured with
the No Network Connection Unless User is Logged In option.
Private - PACS that are stored in the private store can be accessed and used
only by the user who provisioned them or the system administrator. They are
not accessible until the user is logged onto the local system. This is the default
option.
Click Import. The PAC file appears under the selected group.
To delete a group, select the group and click Delete. You can also delete the
group by right-clicking the group and choosing Delete.
To close the Select EAP-FAST PAC window, click Close.
To automatically use PACs belonging to the same PAC authority group, check
the Use Any PAC Belonging to the Same Group check box.
Check the Use Machine PAC for Domain Logon check box if you want the
client to attempt to log into a domain using machine authentication with user
credentials rather than user authentication. Doing so enables your computer to
connect to the network prior to user logon. The default setting is unchecked.
Click OK when done configuring EAP-FAST.
EAP-TLS
To use EAP-TLS security In the Atheros Client Utility, access the Security
tab in the Profile Management window.
On the Security tab, choose the WPA radio button.
OR: On the Security tab, choose the 802.1x radio button.
Choose EAP-TLS from the drop-down menu.
Enabling EAP-TLS security:
To use EAP-TLS security, the machine must already have the EAP-TLS
certificates downloaded onto it. Check with the IT manager.
If EAP-TLS is supported, choose EAP-TLS from the drop-down menu on the
right, then click the Configure button.
Click Configure. The Define Certificate window appears.
Check the Use Machine Information for Domain Login check box if you want
the client to attempt to log into a domain using machine authentication with a
machine certificate and machine credentials rather than user authentication.
Doing so enables your computer to connect to the network prior to user logon.
The default setting is unchecked.
Note: If you do not check the Use Machine Information for Domain Logon
23
check box, machine authentication is not performed. Authentication does not
occur until you log on.
Check the Validate Server Identity check box to force the system to
authenticate the identity of the server as an added level of security.
If you checked the Use Machine Information For Domain Logon check box in
the previous step, the Always Do User Authentication check box at the bottom
of the window becomes active. Perform one of the following:
Check the Always Do User Authentication check box if you want the client to
switch from using machine authentication to using user authentication after
you log on using your username and password. This is the default setting.
Uncheck the Always Do User Authentication check box if you want the client to
continue to use machine authentication after the user's computer logs into the
domain.
Choose your server certificate in the Select a Certificate drop-down list.
Choose the certificate authority from which the server certificate was
downloaded in the Trusted Root Certification Authorities drop-down list.
Perform one of the following:
Leave the Server/Domain Name field blank to allow the client to accept a
certificate from any server that supplies a certificate signed by the certificate
authority listed in the Trusted Root Certification Authorities drop-down list
(recommended).

36
IEEE 802.11 Standard
The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating
a standard for the industry.
Access Point
An internetworking device that seamlessly connects wired and wireless
networks together.
Ad Hoc
An Ad Hoc wireless LAN is a group of computers, each with a WLAN
adapter, connected as an independent wireless LAN. Ad Hoc wireless LAN
is applicable at a departmental scale for a branch or SOHO operation.
BSSID
A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a
BSS must be configured with the same BSSID.
DHCP
Dynamic Host Configuration Protocol - a method in which IP addresses are
assigned by server dynamically to clients on the network. DHCP is used for
Dynamic IP Addressing and requires a dedicated DHCP server on the
network.
Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency
spectrum. The other method is frequency hopping. Direct sequence
spreads the data over one frequency range (channel) while frequency
hopping jumps from one narrow frequency band to another many
times per second.
ESSID
An Infrastructure configuration could also support roaming capability for
mobile workers. More than one BSS can be configured as an Extended
Service Set (ESS). Users within an ESS could roam freely between BSSs
while served as a continuous connection to the network wireless stations
and Access Points within an ESS must be configured with the same ESSID
and the same radio channel.
37
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office
wiring. Users must be wired to the network at all times to gain access.
Gateway
A gateway is a hardware and software device that connects two dissimilar
systems, such as a LAN and a mainframe. In Internet terminology, a gateway
is another name for a router. Generally a gateway is used as a funnel
for all traffic to the Internet.
IEEE
Institute of Electrical and Electronics Engineers
Infrastructure
An integrated wireless and wired LAN is called an Infrastructure
configuration. Infrastructure is applicable to enterprise scale for wireless
access to central database, or wireless application for mobile workers.
ISM Band
The FCC and their counterparts outside of the U.S. have set aside bandwidth
for unlicensed use in the so-called 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.
Local Area Network (LAN)
A LAN is a group of computers, each equipped with the appropriate network
adapter card connected by cable/air, that share applications, data,
and peripherals. All connections are made via cable or wireless media,
but a LAN does not use telephone services. It typically spans a single
building or campus.
Network
A network is a system of computers that is connected. Data, files, and
messages can be transmitted over this network. Networks may be local or
wide area networks.
Protocol
A protocol is a standardized set of rules that specify how a conversation
is to take place, including the format, timing, sequencing and/ or error
checking.
38
Roaming
In an infrastructure network, this is when a wireless PC moves out of
range of the previously connected access point and connects to a newly
connected access point. Throughout the network environment where
access point is deployed, PCs can always be connected regardless of
where they are located or roam.
SSID
A Network ID unique to a network. Only clients and Access Points that
share the same SSID are able to communicate with each other. This string
is case-sensitive.
Simple Network Management Protocol (SNMP)
Simple Network Management Protocol is the network management protocol
of TCP/IP. In SNMP, agents-which can be hardware as well as software-
monitor the activity in the various devices on the network and
report to the network console workstation. Control information about
each device is maintained in a structure known as a management information
block.
Static IP Addressing
A method of assigning IP addresses to clients on the network. In networks
with Static IP address, the network administrator manually assigns an IP
address to each computer. Once a Static IP address is assigned, a computer
uses the same IP address every time it reboots and logs on to the
network, unless it is manually changed.
Temporal Key Integrity Protocol (TKIP)
The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the
IEEE 802.11i encryption standard for wireless LANs. TKIP is the next
generation of WEP, the Wired Equivalency Protocol, which is used to
secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a
message integrity check and a re-keying mechanism, thus fixing the
flaws of WEP.
Transmission Control Protocol / Internet Protocol (TCP/IP)
TCP/IP is the protocol suite developed by the Advanced Research
Projects Agency (ARPA). It is widely used in corporate Internet works,
because of its superior design for WANs. TCP governs how packet is
sequenced for transmission the network. The term “TCP/IP” is often
used generically to refer to the entire suite of related protocols.
39
Transmit / Receive
The wireless throughput in Bytes per second averaged over two seconds.
Wi-Fi Alliance
The Wi-Fi Alliance is a nonprofit international association formed in 1999
to certify interoperability of wireless Local Area Network products based
on IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members is
to enhance the user experience through product interoperability. The
organization is formerly known as WECA.
Wi-Fi Protected Access (WPA)
The Wi-Fi Alliance put together WPA as a data encryption method for
802.11 wireless LANs. WPA is an industry-supported, pre-standard version
of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP),
which fixes the problems of WEP, including using dynamic keys.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone
services and / or fiber optic cabling. WANs may span a city, a state, a
country, or even the world.
Wired Equivalent Privacy (WEP)
Now widely recognized as flawed, WEP was a data encryption method
used to protect the transmission between 802.11 wireless clients and
APs. However, it used the same key among all communicating devices.
WEP’s problems are well-known, including an insufficient key length and
no automated method for distributing the keys. WEP can be easily
cracked in a couple of hours with off-the-shelf tools.
