Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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 54 Mbps Wireless Access Point WG602v3 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 54 Mbps Wireless Access Point WG602v3 How Does WPA Compare to WPA2 (IEEE 802.11i)? WPA is forward compatible with the WPA2 security specification. WPA is a subset of WPA2 and used certain pieces of the early 802.11i draft, such as 802.1x and TKIP. The main pieces of WPA2 that are not included in WPA are secure IBSS (Ad-Hoc mode), secure fast handoff (for specialized 802.11 VoIP phones), as well as enhanced encryption protocols, such as AES-CCMP.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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.

Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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 54 Mbps Wireless Access Point WG602v3 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 54 Mbps Wireless Access Point WG602v3 Is WPA/WPA2 Perfect? WPA/WPA2 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 54 Mbps Wireless Access Point WG602v3 Changes to Wireless Access Points Wireless access points must have their firmware updated to support the following: • • • • • The new WPA/WPA2 information element To advertise their support of WPA/WPA2, wireless APs send the beacon frame with a new 802.11 WPA/WPA2 information element that contains the wireless AP's security configuration (encryption algorithms and wireless security configuration information).
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 Microsoft has worked with many wireless vendors to embed the WPA driver update in the wireless adapter driver. So, to update your Microsoft Windows wireless client, all you have to do is obtain the new WPA/WPA2-compatible driver and install the driver.

They use an eight-bit network number and a 24-bit node number. Class A addresses are in this range: 1.x.x.x to 126.x.x.x. • Class B Class B addresses can have up to 65,354 hosts on a network.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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. Most organizations do not use 64,000 nodes, so there are free bits that can be reassigned. Subnet addressing makes use of those bits that are free, as shown below.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 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. For example, to partition your Class C network with subnet mask 255.255.255.0 into 16 subnets (4 bits), the new subnet mask becomes 255.255.255.240. Table C-1.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 • So that hosts recognize local IP broadcast packets When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address. In order for this scheme to work, all devices on the segment must agree on which bits comprise the host address.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 The following figure illustrates a single IP address operation. Private IP addresses assigned by user IP addresses assigned by ISP 192.168.0.2 192.168.0.3 192.168.0.1 172.21.15.105 Internet 192.168.0.4 192.168.0.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 The router functions as a DHCP client when connecting to the ISP. The firewall can automatically obtain an IP address, subnet mask, DNS server addresses, and a gateway address if the ISP provides this information by DHCP. Domain Name Server Many of the resources on the Internet can be addressed by simple descriptive names such as www.netgear.com.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 MAC Addresses and ARP An IP address alone cannot be used to deliver data from one LAN device to another. To send data between LAN devices, you must convert the IP address of the destination device to its media access control address (MAC address). Each device on an Ethernet network has a unique MAC address, which is a 48-bit number assigned to each device by the manufacturer.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 What is a Firewall? A firewall is a device that protects one network from another, while allowing communication between the two. A firewall incorporates the functions of the NAT router, while adding features for dealing with a hacker intrusion or attack. Several known types of intrusion or attack can be recognized when they occur.

Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 Inside Twisted Pair Cables For two devices to communicate, the transmitter of each device must be connected to the receiver of the other device. The crossover function is usually implemented internally as part of the circuitry in the device. Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports.

However, using telephone cable results in excessive collisions, causing the attached port to be partitioned or disconnected from the network.
Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3 The WG602v3 Access Point incorporates Auto UplinkTM technology (also called MDI/MDIX). Each LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a normal connection (e.g. connecting to a PC) or an uplink connection (e.g. connecting to a router, switch, or hub). That port will then configure itself to the correct configuration.

With this feature, WPA provides roughly comparable security to VPN tunneling with WEP, with the benefit of easier administration and use. This is similar to 802.1x support and requires a RADIUS server in order to implement. The Wi-Fi Alliance will call this, 'WPA-Enterprise.' One variation of WPA is called WPA Pre Shared Key or WPA-PSK for short - this provides an authentication alternative to an expensive RADIUS server.
