Appendix B Wireless Networking Basics This chapter provides an overview of Wireless networking. Wireless Networking Overview The WPN311 Wireless PCI Adapter conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11b and 802.11 g standards for wireless LANs (WLANs)WPN311. On an 802.11b or g wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2.4GHz.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 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 PCI Adapter WPN311 802.11 Authentication The 802.11 standard defines several services that govern how two 802.11 devices communicate. The following events must occur before an 802.11 Station can communicate with an Ethernet network through an access point such as the one built in to the WPN311: 1. Turn on the wireless station. 2. The station listens for messages from any access points that are in range. 3.

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Key Size The IEEE 802.11 standard supports two types of WEP encryption: 40-bit and 128-bit. The 64-bit WEP data encryption method, allows for a five-character (40-bit) input. Additionally, 24 factory-set bits are added to the forty-bit input to generate a 64-bit encryption key. (The 24 factory-set bits are not user-configurable). This encryption key will be used to encrypt/decrypt all data transmitted via the wireless interface.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Note: Whatever keys you enter for an AP, you must also enter the same keys for the client adapter in the same order. In other words, WEP key 1 on the AP must match WEP key 1 on the client adapter, WEP key 2 on the AP must match WEP key 2 on the client adapter, etc. Note: The AP and the client adapters can have different default WEP Keys as long as the keys are in the same order.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 The radio frequency channels used are listed in Table 5-1: Table 5-1. 802.11b and g Radio Frequency Channels Channel Center Frequency Frequency Spread 1 2412 MHz 2399.5 MHz - 2424.5 MHz 2 2417 MHz 2404.5 MHz - 2429.5 MHz 3 2422 MHz 2409.5 MHz - 2434.5 MHz 4 2427 MHz 2414.5 MHz - 2439.5 MHz 5 2432 MHz 2419.5 MHz - 2444.5 MHz 6 2437 MHz 2424.5 MHz - 2449.5 MHz 7 2442 MHz 2429.5 MHz - 2454.5 MHz 8 2447 MHz 2434.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 The IEEE introduced the WEP as an optional security measure to secure 802.11b (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 in October 2002 that remedies the shortcomings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to work with existing 802.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 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 PCI Adapter WPN311 The strength of WPA comes from an integrated sequence of operations that encompass 802.1X/ EAP authentication and sophisticated key management and encryption techniques. Its major operations include: • Network security capability determination. This occurs at the 802.11 level and is communicated through WPA information elements in Beacon, Probe Response, and (Re) Association Requests.

User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 3. The client sends an EAP-response packet containing the identity to the authentication server. The access point responds by enabling a port for passing only EAP packets from the client to an authentication server located on the wired side of the access point. The access point blocks all other traffic, such as HTTP, DHCi 6(5.5(accnd5.5(acPOP3)-7(5.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Temporal Key Integrity Protocol (TKIP) WPA uses TKIP to provide important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the following: • • • The verification of the security configuration after the encryption keys are determined.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Is WPA Perfect? WPA is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS) attacks. If the access point receives two data packets that fail the message integrity code (MIC) within 60 seconds of each other, then the network is under an active attack, and as a result, the access point employs counter measures, which include disassociating each station using the access point.
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Changes to Wireless Access Points Wireless access points must have their firmware updated to support the following: • • • • • The new WPA information element To advertise their support of WPA, wireless APs send the beacon frame with a new 802.11 WPA information element that contains the wireless AP's security configuration (encryption algorithms and wireless security configuration information).
User Manual for the NETGEAR RangeMax™ Wireless PCI Adapter WPN311 Microsoft has worked with many wireless vendors to embed the WPA firmware update in the wireless adapter driver. So, to update your Microsoft Windows wireless client, all you have to do is obtain the new WPA-compatible driver and install the driver. The firmware is automatically updated when the wireless network adapter driver is loaded in Windows.
