CHAPTER 2 Wireless LANs 2.1 Overview This section provides background information on wireless Local Area Networks. 2.1.1 What You Can Do in This Section • Connect securely to an AP using many of the strongest and most common encryption protocols. See Section 2.3 on page 27 for details. • Connect securely either to an AP or computer-to-computer using WPS. See Section 2.4 on page 29 for details. 2.1.2 What You Need to Know The following terms and concepts may help as you read through this section.
Chapter 2 Wireless LANs Encryption The process of taking data and encoding it, usually using a mathematical formula, so that it becomes unreadable unless decrypted with the proper code or pass phrase. 2.1.3 Before You Begin • You should have valid login information for an existing network Access Point, otherwise you may not be able to make a network connection right away. 2.2 Wireless LAN Overview The following figure provides an example of a wireless network with an AP.
Chapter 2 Wireless LANs • If two wireless networks overlap, they should use a different channel. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. • Every device in the same wireless network must use security compatible with the AP or peer computer. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 2.
Chapter 2 Wireless LANs • Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN. For WLAN adapters without the passphrase feature, you can still take advantage of this feature by writing down the four automatically generated WEP keys from the Security Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the other WLAN adapter(s).
Chapter 2 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). Certificates (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. 2.3.1.3 WPA and WPA2 Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.
Chapter 2 Wireless LANs Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves. 2.4.
Chapter 2 Wireless LANs When you use the PIN method, you must enter the PIN from one device (usually the wireless client) into the second device (usually the Access Point or wireless router). Then, when WPS is activated on the first device, it presents its PIN to the second device. If the PIN matches, one device sends the network and security information to the other, allowing it to join the network.
Chapter 2 Wireless LANs The following figure shows a WPS-enabled wireless client (installed in a notebook computer) connecting to the WPS-enabled AP via the PIN method. Figure 5 Example WPS Process: PIN Method ENROLLEE REGISTRAR WPS This device’s WPS PIN: 123456 WPS Enter WPS PIN from other device: WPS START WPS START WITHIN 2 MINUTES SECURE EAP TUNNEL SSID WPA(2)-PSK COMMUNICATION 2.4.3 How WPS Works When two WPS-enabled devices connect, each device must assume a specific role.
Chapter 2 Wireless LANs already part of a network, it sends the existing information. If not, it generates the SSID and WPA(2)-PSK randomly. The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point.
Chapter 2 Wireless LANs subsequent WPS connections in which it is involved. If you want a configured AP to act as an enrollee, you must reset it to its factory defaults. 2.4.3.1 Example WPS Network Setup This section shows how security settings are distributed in an example WPS setup. The following figure shows an example network. In step 1, both AP1 and Client 1 are unconfigured. When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and Client 1 is the enrollee.
Chapter 2 Wireless LANs 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 9 WPS: Example Network Step 3 EXISTING CONNECTION CLIENT 1 E N TIO EC N ON GC N I T XIS AP1 REGISTRAR CLIENT 2 SE CU RIT Y INF O ENROLLEE AP1 2.4.
Chapter 2 Wireless LANs • WPS works only with other WPS-enabled devices. However, you can still add non-WPS devices to a network you already set up using WPS. WPS works by automatically issuing a randomly-generated WPA-PSK or WPA2PSK pre-shared key from the registrar device to the enrollee devices. Whether the network uses WPA-PSK or WPA2-PSK depends on the device.
CHAPTER 3 ZyXEL Utility - Mac OS X 3.1 Overview This chapter shows you how to use the ZyXEL utility to configure your NWD2205 using the Macintosh operating system, Mac OS X. 3.1.1 What You Can Do in This Chapter • The Link Status screen (Section 3.3 on page 39) lets you see your current connection details, monitor signal strength and quality, and more. • The Profiles screen (Section 3.4 on page 40) lets you create, delete and manage your wireless network profiles.
Chapter 3 ZyXEL Utility - Mac OS X Wi-Fi Protected Access (WPA) The WPA protocol affords users with vastly stronger security than WEP. It comes in two different varieties: WPA and WPA2. Always try to use WPA2 as it implements the full version of the security standard and WPA does not. Pre-Shared Key (PSK) A pre-shared key is a password shared between the server and the client that unlocks the algorithm used to encrypt the data traffic between them.

APPENDIX A Wireless LANs This appendix 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 A Wireless LANs BSS A Basic Service Set (BSS) exists when all communications between wireless clients or between a wireless client and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other.
Appendix A Wireless LANs 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 A Wireless LANs adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11. RTS/CTS A hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node.
Appendix A Wireless LANs If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), 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. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.
Appendix A Wireless LANs IEEE 802.11g Wireless LAN IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows: Table 12 IEEE 802.
Appendix A Wireless LANs Note: You must enable the same wireless security settings on the NWD2205 and on all wireless clients that you want to associate with it. IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.
Appendix A Wireless LANs • Access-Reject Sent by a RADIUS server rejecting access. • Access-Accept Sent by a RADIUS server allowing access. • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message.
Appendix A Wireless LANs 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. The wireless client ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses.
Appendix A Wireless LANs LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. 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.
Appendix A Wireless LANs If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2-PSK (WPA2-Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN.
Appendix A Wireless LANs The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys.
Appendix A Wireless LANs 2 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. 3 A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client. 4 The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys.
Appendix A Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 23 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 A 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 A Wireless LANs • Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points. • Directional antennas concentrate the RF signal in a beam, like a flashlight does with the light from its bulb.
