Appendix B Wireless Networking Basics This chapter provides an overview of wireless networking and security. Wireless Networking Overview The RangeMax™ WPN111 Wireless USB 2.0 Adapter conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11b standard for wireless LANs (WLANs) and a product update will bring the WPN111 into conformance to the 802.11g standard when it is ratified. On an 802.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 Ad Hoc Mode (Peer-to-Peer Workgroup) In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network - each node can generally communicate with any other node. There is no access point involved in this configuration.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 802.11b/g Wireless Channels IEEE 802.11b/g wireless nodes communicate with each other using radio frequency signals in the ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the center channel frequency.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 Note: The available channels supported by the wireless products in various countries are different. For example, Channels 1 to 11 are supported in the U.S. and Canada, and Channels 1 to 13 are supported in Europe and Australia. The preferred channel separation between the channels in neighboring wireless networks is 25 MHz (5 channels). This means that you can apply up to three different channels within your wireless network.

The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and sends the encrypted text to the access point. 4. The access point decrypts the encrypted text using its configured WEP Key that corresponds to the station’s default key. The access point compares the decrypted text with the original challenge text.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 When configured for 128-bit encryption, 802.11 products typically support four WEP Keys but some manufacturers support only one 128-bit key. The 128-bit WEP Key is expressed as 13 sets of two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90 AB CD EF 12 34 56 78 90” is a 128-bit WEP Key. Typically, 802.11 access points can store up to four 128-bit WEP Keys but some 802.11 client adapters can only store one.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key Authentication without data encryption). However, the WPN111 does not offer this option. 802.1x Port Based Network Access Control Securing any kind of network involves allowing authorized parties to access traffic and networked resources (e.g., servers, hosts) while blocking outsiders.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 IEEE 802.1x offers an effective framework for authenticating and controlling user traffic to a protected network, as well as dynamically varying encryption keys. 802.1x ties a protocol called EAP (Extensible Authentication Protocol) to both the wired and wireless LAN media and supports multiple authentication methods, such as token cards, Kerberos, one-time passwords, certificates, and public key authentication.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 7. If the authentication server accepts the client, then the access point will transition the client's port to an authorized state and forward additional traffic. Initial 802.1x communications begin with an unauthenticated supplicant (i.e., client device) attempting to connect with an authenticator (i.e., 802.11 access point).
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 The IEEE introduced the WEP as an optional security measure to secure 802.11 (Wi-Fi) WLANs, but inherent weaknesses in the standard soon became obvious. In response to this situation, the Wi-Fi Alliance announced a new security architecture that remedies the short comings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to work with existing 802.11 products and offers forward compatibility with 802.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 For 802.11, WEP encryption is optional. For WPA, encryption using Temporal Key Integrity Protocol (TKIP) is required. TKIP replaces WEP with a new encryption algorithm that is stronger than the WEP algorithm, but that uses the calculation facilities present on existing wireless devices to perform encryption operations.

User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 The supplicant in the station uses the authentication and cipher suite information contained in the information elements to decide which authentication method and cipher suite to use. For example, if the access point is using the Pre-shared key method then the supplicant need not authenticate using full-blown 802.1X. Rather, the supplicant must simply prove to the access point that it is in possession of the pre-shared key.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 The AP sends Beacon Frames with WPA information element to the stations in the service set. Information elements include the required authentication method (802.1x or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES). Probe Responses (AP to station) and Association Requests (station to AP) also contain WPA information elements. 1. Initial 802.1x communications begin with an unauthenticated supplicant (i.e.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 Note: For environments with a Remote Authentication Dial-In User Service (RADIUS) infrastructure, WPA supports Extensible Authentication Protocol (EAP). For environments without a RADIUS infrastructure, WPA supports the use of a preshared key. Together, these technologies provide a framework for strong user authentication. WPA Data Encryption Key Management With 802.1x, the rekeying of unicast encryption keys is optional.
User Manual for the NETGEAR RangeMax™ Wireless USB 2.0 Adapter WPN111 With 802.11 and WEP, data integrity is provided by a 32-bit integrity check value (ICV) that is appended to the 802.11 payload and encrypted with WEP. Although the ICV is encrypted, you can use cryptanalysis to change bits in the encrypted payload and update the encrypted ICV without being detected by the receiver.
