Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point WEP Configuration Options The WEP settings must match on all 802.11 devices that are within the same wireless network as identified by the SSID. In general, if your mobile clients will roam between access points, then all of the 802.11 access points and all of the 802.11 client adapters on the network must have the same WEP settings.

Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point WPA offers the following benefits: • • • • Enhanced data privacy Robust key management Data origin authentication Data integrity protection The Wi-Fi Alliance is now performing interoperability certification testing on Wi-Fi Protected Access products. Starting August of 2003, all new Wi-Fi certified products will have to support WPA.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point How Does WPA Compare to IEEE 802.11i? WPA will be forward compatible with the IEEE 802.11i security specification currently under development. WPA is a subset of the current 802.11i draft and uses certain pieces of the 802.11i draft that are ready to bring to market today, such as 802.1x and TKIP. The main pieces of the 802.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point.

Information elements include the required authentication method (802.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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).
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point 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.

Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point also Reverse ARP (RARP) which can be used by a host to discover its IP address. In this case, the host broadcasts its physical address and a RARP server replies with the host's IP address. Auto Uplink Auto UplinkTM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs. straight-through Ethernet cables. Auto UplinkTM will accommodate either type of cable to make the right connection.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point IP Address A four-byte number uniquely defining each host on the Internet, usually written in dotted-decimal notation with periods separating the bytes (for example, 134.177.244.57). Ranges of addresses are assigned by Internic, an organization formed for this purpose. ISP Internet service provider. Internet Protocol The main internetworking protocol used in the Internet.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point NetBIOS Network Basic Input Output System. An application programming interface (API) for sharing services and information on local-area networks (LANs). Provides for communication between stations of a network where each station is given a name. These names are alphanumeric names, 16 characters in length.
Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point This is typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in the wireless Access Point and to the wireless network name. See also Wireless Network Name and ESSID. Subnet Mask Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router.
