Reference Manual for the NETGEAR ProSafe Wireless Access Point 802.11g WG302 – Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. However, some access points allow connections from wireless stations which have their SSID set to “any” or whose SSID is blank (null). – A group of wireless stations and multiple access points, all using the same ID (ESSID), form an Extended Service Set (ESS).
Reference Manual for the NETGEAR ProSafe Wireless Access Point 802.11g WG302 Note: Channel selection is automatically adjusted by AutoCell when the Auto RF Management option is enabled. The default setting is for the AutoCell Auto RF Management option to be enabled. – Access points use a fixed channel. You can select the channel used. This allows you to choose a channel which provides the least interference and best performance. In the USA and Canada, 11 channels are available.
Reference Manual for the NETGEAR ProSafe Wireless Access Point 802.11g WG302 Figure 3-8: Wireless Security Settings • Enable Wireless Client Security Separator The associated wireless clients will not be able to communicate with each other if this feature is enabled.

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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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.
Appendix C Command Line Reference The NETGEAR ProSafe Wireless Access Point 802.11g WG302 (AP) can be configured either through the command line interface (CLI), a Web browser, or an MIB browser. The CLI allows viewing and modification of the configuration from a terminal or PC through a telnet connection.

Reference Manual for the NETGEAR ProSafe Wireless Access Point 802.11g WG302 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 ProSafe Wireless Access Point 802.11g WG302 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.
