Computers use radio communications to send data between each other. You can communicate directly with other wireless computers, or connect to an existing network through a wireless access point.
Peer-to-Peer mode, also called Ad Hoc mode, works without access points and allows wireless computers to send information directly to other wireless computers. Ad Hoc Mode is only supported in 802.11b and 802.11g networks. You can use Peer-to-Peer mode to network computers in a home or small office or to set up a temporary wireless network for a meeting. Configuring a Wireless LAN There are three basic components that must be configured for an 802.
● locations. Security: The 802.11 wireless networks use encryption to help protect your data. Wired equivalent privacy (WEP) uses a 64-bit or 128-bit shared encryption key to scramble data. Before a computer transmits data, it scrambles the data using the secret encryption key. The receiving computer uses this same key to unscramble the data. If you are connecting to an existing network, use the encryption key provided by the administrator of the wireless network.
packets with the broadcast SSID. If this feature is enabled on the access point, any wireless user can associate with the access point by using a blank (null) SSID. Surveying the Site of Your Wireless LAN Conducting a site survey for your wireless LAN is the most crucial step in the process of setting up a wireless network. It greatly reduces the amount of troubleshooting you will have to do once you have the wireless LAN set up and ready for connection testing.
best location for access points. Factors Affecting Range Although access points can transmit signals up to 60 feet away in an area with many walled barriers or as much as 500 feet away in a large open area, the range is affected by the following factors: ● ● ● ● Building materials, such as steel and drywall, can shorten the range of the radio signals. Physical layout of the area can interfere with the signals and cause them to be dropped.
● you need a different level of coverage in some areas, you may need to move, replace, or supplement access points and antennas. You are physically changing the site: Remodeling may introduce new sources of interference, such as motors and metal structures within the coverage area of the access point, even if it does not directly effect the sites where the access points are located. Elements of an Effective Site Survey An effective site survey requires four elements.

Protecting Your Network ● ● ● ● ● ● Authentication Types 802.1x Authentication What is a RADIUS Wi-Fi Protected Access (WPA) PEAP Cisco LEAP Authentication Types The IEEE 802.1x standard provides a general authentication framework for 802 LANs and specifies an extensible authentication protocol (EAP) to enable LAN transport for many different types of authentication protocols.
● 802.1x supplicant protocol support ● Support for the Extensible Authentication Protocol (EAP) - RFC 2284 ● Supported Authentication Methods: ● ● MD5 - RFC 2284 ● EAP TLS Authentication Protocol - RFC 2716 and RFC 2246 ● EAP Tunneled TLS (TTLS) ● Cisco LEAP ● PEAP Supports Windows XP, 2000 802.1x Authentication Notes ● ● ● 802.1x authentication methods, include passwords, certificates, and smart cards (plastic cards that hold data) 802.
Remote Authentication Dial-In User Service (RADIUS) server connected to the access point. The authentication process uses credentials, such as a user's password that are not transmitted over the wireless network. Most 802.1x types support dynamic per-user, per-session keys to strengthen the static key security. 802.1x benefits from the use of an existing authentication protocol known as the Extensible Authentication Protocol (EAP). 802.
RADIUS is the Remote Access Dial-In User Service, an Authorization, Authentication, and Accounting (AAA) client-server protocol for when a AAA dial-up client logs in or out of a Network Access Server. Typically, a RADIUS server is used by Internet Service Providers (ISP) to performs AAA tasks. AAA phases are described as follows: ● ● ● Authentication phase: Verifies a user name and password against a local database. After the credentials are verified, the authorization process begins.
Cisco LEAP (EAP Cisco Wireless) is a server and client 802.1x authentication via a usersupplied logon password. When a wireless access point communicates with a Cisco LEAP-enabled RADIUS (Cisco Secure Access Control Server (ACS) server), Cisco LEAP provides access control through mutual authentication between client wireless adapters and the wireless network and provides dynamic, individual user encryption keys to help protect the privacy of transmitted data.

● ● Using Open authentication, any wireless station can request authentication. The station that needs to authenticate with another wireless station sends an authentication management frame that contains the identity of the sending station. The receiving station or AP will grant any request for authentication. Open authentication allows any device network access. If no encryption is enabled on the network, any device that knows the SSID of the access point can gain access to the network.
Encryption Overview Security in the WLAN can be supplemented by enabling data encryption using WEP (Wireless Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also, the data can then be encrypted with a key. Another parameter called the key index is provides the option to create multiple keys for that profile. However, only one key can be used at a time. You can also choose to password protect the profile to ensure privacy. The pass phrase is used to generate a WEP key automatically.

NOTE: You must use the same encryption type, index number, and WEP key as other devices on your wireless network.
Step 1: Getting a certificate To allow TLS authentication, you need a valid client (user) certificate in the local repository for the logged-in user’s account. You also need a trusted CA certificate in the root store. The following information provides two methods for getting a certificate; ● ● from a corporate certification authority implemented on a Windows 2000 Server using Internet Explorer’s certificate import wizard to import a certificate from a file Getting a certificate from a Windows 2000 CA: 1.

Client: In this case the client needs to send out an authentication algorithm value of 0x80 else the 802.11 authentication handshake would fail. During boot, when the Wireless LAN driver is already loaded, but the Intel(R) PROSet supplicant is still unloaded, the client sends 802.11 authentication with an Authentication algorithm value of 0x0. Once the Intel(R) PROSet supplicant loads, and engages the LEAP profile, it sends 802.11 authentication with an Authentication algorithm value of 0x80.
Some non-Intel clients, for example, when set to LEAP, cannot authenticate in this case. However, the Intel Wireless LAN client can authenticate, if the Rogue AP is unchecked. Rogue AP Checkbox configuration When the checkbox is checked it ensures that the client implements the Rogue AP feature as required by CCX. The client makes note of APs that it failed to authenticate with and sends this information to the AP that allows it to authenticate and connect.
