CHAPTER 6 Wireless LAN This chapter discusses how to configure the wireless network settings in your PLA450. See the appendices for more detailed information about wireless networks. 6.1 Wireless Network Overview The following figure provides an example of a wireless network. Figure 28 Example of a Wireless Network AP A B The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
Chapter 6 Wireless LAN Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. • Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.
Chapter 6 Wireless LAN • Security: ( ) None ( ) WEP (64 bit or 128 bit key) (ASCII or Hex):________________ 6.2 Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. 6.2.1 SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID.
Chapter 6 Wireless LAN If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.
Chapter 6 Wireless LAN Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. 6.3 Roaming A wireless station is a device with an IEEE 802.11a/b/g compliant wireless interface. An access point (AP) acts as a bridge between the wireless and wired networks. An AP creates its own wireless coverage area.
Chapter 6 Wireless LAN Figure 29 Roaming Example AP 1 AP 2 X Y Y The steps below describe the roaming process. 1 Wireless station Y moves from the coverage area of access point AP 1 to that of access point AP 2. 2 Wireless station Y scans and detects the signal of access point AP 2. 3 Wireless station Y sends an association request to access point AP 2. 4 Access point AP 2 acknowledges the presence of wireless station Y and relays this information to access point AP 1 through the wired LAN.
Chapter 6 Wireless LAN 6.4.1 WMM QoS WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless networks. It controls WLAN transmission priority on packets to be transmitted over the wireless network. WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks. On APs without WMM QoS, all traffic streams are given the same access priority to the wireless network.
Chapter 6 Wireless LAN 6.5.1 WPS Setup Using a PIN Each WPS-enabled device has its own PIN (Personal Identification Number). This may either be static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by clicking on a button in the configuration interface).
Chapter 6 Wireless LAN 6.5.2 How WPS Works When two WPS-enabled devices connect, each device must assume a specific role. One device acts as the registrar (the device that supplies network and security settings) and the other device acts as the enrollee (the device that receives network and security settings. The registrar creates a secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the WPA-PSK or WPA2-PSK pre-shared key to the enrollee.
Chapter 6 Wireless LAN By default, a WPS devices is “unconfigured”. This means that it is not part of an existing network and can act as either enrollee or registrar (if it supports both functions). If the registrar is unconfigured, the security settings it transmits to the enrollee are randomly-generated. Once a WPS-enabled device has connected to another device using WPS, it becomes “configured”.
Chapter 6 Wireless LAN In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead. Figure 33 WPS: Example Network Step 3 EXISTING CONNECTION CLIENT 1 E ION CT E NN CO G TIN XIS AP1 REGISTRAR CLIENT 2 SE CU RIT Y ENROLLEE INF O AP1 6.5.
Chapter 6 Wireless LAN • When you use the PBC method, there is a short period (from the moment you press the button on one device to the moment you press the button on the other device) when any WPS-enabled device could join the network. This is because the registrar has no way of identifying the “correct” enrollee, and cannot differentiate between your enrollee and a rogue device. This is a possible way for a hacker to gain access to a network. 6.
Chapter 6 Wireless LAN Table 12 Network > Wireless LAN > General LABEL DESCRIPTION Channel Selection Set the operating frequency/channel depending on your particular region. Select a channel from the drop-down list box. The options vary depending on the IEEE 802.11 mode you are using and the country you are in. Refer to Appendix D on page 159 for more information on channels. Operating Channel This displays the channel the PLA450 is currently using.
Chapter 6 Wireless LAN 6.6.2 WPA-PSK/WPA2-PSK Click Network > Wireless LAN to display the General screen. Select WPA-PSK or WPA2PSK from the Security Mode list. Figure 36 Network > Wireless LAN > General: WPA-PSK/WPA2-PSK The following table describes the labels in this screen. Table 14 Network > Wireless LAN > General: WPA-PSK/WPA2-PSK LABEL DESCRIPTION WPA Compatible This check box is available only when you select WPA2-PSK or WPA2 in the Security Mode field.
Chapter 6 Wireless LAN Table 14 Network > Wireless LAN > General: WPA-PSK/WPA2-PSK LABEL DESCRIPTION Group Key Update Timer The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/ WPA2-PSK key management) or RADIUS server (if using WPA/WPA2 key management) sends a new group key out to all clients. The re-keying process is the WPA/WPA2 equivalent of automatically changing the WEP key for an AP and all stations in a WLAN on a periodic basis.

APPENDIX B IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.
Appendix B IP Addresses and Subnetting Figure 75 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “subnetwork”. A subnet mask has 32 bits.
Appendix B IP Addresses and Subnetting Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.

APPENDIX D Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
Appendix D Wireless LANs Figure 102 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood.
Appendix D Wireless LANs Figure 103 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.
Appendix D Wireless LANs Figure 104 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations. RTS/CTS is designed to prevent collisions due to hidden nodes.
Appendix D Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet.
Appendix D Wireless LANs Wireless security methods available on the PLA450 are data encryption, wireless client authentication, restricting access by device MAC address and hiding the PLA450 identity. The following figure shows the relative effectiveness of these wireless security methods available on your PLA450. Table 51 Wireless Security Levels SECURITY LEVEL SECURITY TYPE Least Secure Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE802.
Appendix D Wireless LANs Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server.
Appendix D Wireless LANs For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client.
Appendix D Wireless LANs Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the wireless security configuration screen.
Appendix D Wireless LANs Encryption Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. WPA and WPA2 use Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption than TKIP. TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server.
Appendix D Wireless LANs Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's builtin “Zero Configuration" wireless client. However, you must run Windows XP to use it.
Appendix D Wireless LANs 3 The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. 4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them. Figure 106 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type.
Appendix D Wireless LANs Antenna Overview An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.
Appendix D Wireless LANs Positioning Antennas In general, antennas should be mounted as high as practically possible and free of obstructions. In point-to–point application, position both antennas at the same height and in a direct line of sight to each other to attain the best performance. For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down.
