User’s Guide for the WG602 v3 54 Mbps 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. - Page 71 User’s Guide for the WG602 v3 54 Mbps 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.

Page 80: Ip Addresses And The Internet
User’s Guide for the WG602 v3 54 Mbps Wireless Access Point IP Addresses and the Internet Because TCP/IP networks are interconnected across the world, every machine on the Internet must have a unique address to make sure that transmitted data reaches the correct destination. Blocks of addresses are assigned to organizations by the Internet Assigned Numbers Authority (IANA). - Page 81 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point Class A Network Node Class B Network Node Class C Network Node 7261 Figure C-1: Three Main Address Classes The five address classes are: • Class A Class A addresses can have up to 16,777,214 hosts on a single network. They use an eight-bit network number and a 24-bit node number.
-
Page 82: Netmask
User’s Guide for the WG602 v3 54 Mbps Wireless Access Point This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host. - Page 83 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes.
- Page 84 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point The following table lists the additional subnet mask bits in dotted-decimal notation. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits.

Glossary Use the list below to find definitions for technical terms used in this manual. Numeric 802.1x 802.1x defines port-based, network access control used to provide authenticated network access and automated data encryption key management. The IEEE 802.1x draft standard offers an effective framework for authenticating and controlling user traffic to a protected network, as well as dynamically varying encryption keys. - Page 108 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point Access Control List An ACL is a database that an Operating System uses to track each user’s access rights to system objects (such as file directories and/or files). See “Access Control List” Ad-hoc Mode An 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP).

- Page 110 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point Dynamic Host Configuration Protocol. DHCP is a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network. In some systems, the device's IP address can even change while it is still connected.

However, IP version 6 (IPv6) is also beginning to be supported. IPv6 provides for much longer addresses and therefore for the possibility of many more Internet users.
- Page 113 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point MAC address The Media Access Control address is a unique 48-bit hardware address assigned to every network interface card. Usually written in the form 01:23:45:67:89:ab. Maximum Receive Unit The size in bytes of the largest packet that can be sent or received. Maximum Transmit Unit The size in bytes of the largest packet that can be sent or received.
- Page 114 User’s Guide for the WG602 v3 54 Mbps Wireless Access Point Network Address Translation Sometimes referred to as Transparent Proxying, IP Address Overloading, or IP Masquerading. Involves use of a device called a Network Address Translator, which assigns a contrived, or logical, IP address and port number to each node on an organization's internal network and passes packets using these assigned addresses.
