Introduction:

Overview

Wireless Networking Overview

A Look at the Hardware

Overview

The Dell Wireless 2350 Broadband Router is an 802.11b/g wireless access point with a built-in Internet router. Connecting to a DSL or cable modem, the Wireless 2350 can offer both wired and wireless computers simultaneous access to the Internet. The Wireless 2350 can be configured the following ways:

• Internet router: Connects to a cable or DSL modem providing Internet connectivity to both wired and wireless computers. The firewall features included in the router control Internet access and protect your network.

• Wireless hub (Access Point): Connects wireless computers for file and print sharing.

• 4-port Ethernet switch: Connects four wired computers for file and print shari ng.

• Ethernet bridge: Enables file and print sharing between wired and wireless

computers. In addition, connects to an Ethernet hub, extending Internet connectivity and sharing to more wired computers.

The Wireless 2350 supports up to 252 clients. Up to 16 of the 252 clients can be wireless. The Network Address Translation (NAT) feature allows 32 clients to simultaneously communicate out to the Internet. It runs at speeds up to 54 Megabits per second (Mbps), an d the LAN (wired) port runs at 10/100 Mbps. The maximum distance between the Wireless 2350 and each Wireless computer is 300 feet. This distance may be less depending on your environment.

By default, you can use the Wireless 2350 in the following ways:

• a wireless access point using wireless as the wireless network name.

• a DHCP server that provides IP addresses to wireless and wired clients.

• a bridge to an Ethernet hub.

Wireless Networking Overview:

Wireless Local Area Network (WLAN)

Identifying a WLAN

Encryption

Automatic Rate Selection and Rate Scaling

Wireless Local Area Network (WLAN)

A Local Area Network (LAN) is a network in one location. Users at that location can share files, printers, and other services. In a LAN, a networked computer that requests services is called a client. A Wireless Local Area Network (WLAN) is a type of LAN that uses high frequency radio waves rather than wires to communicate and transmit data among the networ k clients and devices. It is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN.

In a WLAN, wireless adapters are installed in clients, also called wirele ss clients. The adapter allows the wireless client to communicate with the WLAN without cables. Instead, wireless clients send and receive information through a path in the air called a channel.

The standards for a WLAN are based on the IEEE 802.11b standard and IEEE 802.11g standard. All Dell 802.11b/g-compliant devices interoperate with other 802.11b/g -compliant wireless devices from other vendors. The WiFi certification logo indicates that the wireless device has been tested by an independent organization.

A wireless client operates in either infrastructure mode or peer-to-peer mode.

Identifying a WLAN

An ESSID and BSSID are both Service Set Identifiers (SSID) that identify and control the wireless client’s access to a given WLAN. The SSID is sometimes referred to as the network name. The SSID indicates what WLAN you are referring to. In most cases, the user interface displays the SSID.

When installing an access point or wireless adapter in a wireless client, the installation program asks you to enter the SSID. Dell cannot provide you with this information, as it is specific to your network; but you may choose to use the default SSID, wireless, for your Wireless 2350. All wireless clients and access points in a WLAN must use the same network name.

Encryption

In a WLAN, wireless clients and access points send and receive information through the air. Without implementing security, it is possible for an unauthorized person to intercept the information.

A common way of implementing security and protecting information is encryption. Encryption applies a set of instructions, called an algorithm, to information. The instructions combine the plain or clear text of information with a sequence of hexadecimal numbers, called an encryption key.

Before transmitting information over the airwaves, the wireless client or access point encrypts or scrambles the information. The access point or wireless client receiving the information uses the same key to decrypt or unscramble the information. The information is only readable to WLAN devices that have the correct encryption key. The longer the key is, the stronger the encryption.

The Wireless 2350 supports both Wired Equivalent Privacy (WEP) and Wi-Fi Protected

Access (WPA).

WEP

WEP (Wired Equivalent Privacy) provides a way of creating an encrypted key that is shared between a wireless client (such as a notebook with a wireless PC card) and the router. In the Wireless 2350, WEP is an optional feature that can be enabled or disabled. When WEP encryption is enabled, you must set the WEP key in the client to match the WEP key used by

the access point because you can ONLY connect to access points that have a matching WEP Key.

NOTE:

It is better to change keys frequently. The same algorithm is used for all the communications that should be protected. If the same key is used, the same message will give exactly the same cipher text. Then, it will be possible for an eavesdropper to break the encrypted data. For this reason, it is strongly recommended to change keys often.

There are two WEP encryption methods:

• •

40(64)-bit Encryption

• •

104(128)-bit Encryption

40-bit and 64-bit encryption are identical. Some vendors use the term 40-bit; others use 64-bit. A wireless device that claims to have 40-bit encryption interoperates with a device that claims to have 64-bit encryption; the same is true for the reverse. A 40(64)-bit key consists of 10 hexadecimal numbers, arrayed as follows:

Key #1: 1011121314

Key #2: 2021222324

Key #3: 3031323334

Key #4: 4041424344

A 104(128)-bit key has several trillion times as many possible combinations than a 40(64)-bit key. It consists of 26 hexadecimal numbers, arrayed as follows:

Key (#1): 101112131415161718191A1B1C

All wireless clients and access points in a WLAN must use the same encryption method and key. The following two examples stress how important this point is.

Example 1

The encryption method for an access point is 40(64)-bit. The method for a wireless client is 104(128)-bit encryption. The client and access point cannot communicate with each other, even though the selected key is the same. To resolve this problem, set the access point to use 104(128)-bit encryption.

Example 2

The encryption method is the same for the access point and wireless client. You select key 1 for the access point and key 2 for the wireless client. The wireless client cannot communicate with the WLAN. To resolve this problem, select key 1 for the wireless client.

NOTE:

Use the same key and encryption method for the wireless devices in the WLAN. Otherwise, they cannot communicate with each other.

The Wireless 2350 uses either hexadecimal digits or ASCII characters to create encryption keys. Hexadecimal digits include the numbers 0 to 9 and the letters A to F. For example, the decimal number 15 is represented as F in the hexadecimal numbering system.

ASCII is the acronym for the American Standard Code for Information Interchange. Pronounced ask-ee, ASCII is a code for representing English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code for uppercase M is

77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.

WPA

WPA (Wi-Fi Protected Access) is an upgrade to the WEP standard for securing your wireless network. WPA is derived from and will be forward-compatible with the future IEEE 802.11i standard. It provides improved data encryption and user authentication.

To enhance the level of security, WPA uses Temporal Key Integrity Protocol (TKIP) encryption to address the vulnerabilities of the static keys used in WEP. TKIP includes four algorithms: message integrity check (MIC), to protect packets from tampering; Per-Packet Key (PPK) hashing, to prevent weak key attacks; extended initialization vector (IV), to reduce IV reuse and the possibility that a hacker will collect sufficient packets to crack the encryption; and a re-keying mechanism, to change the temporal key dynamically. TKIP is the most commonly used encryption method; however, if your wireless clients do not support TKIP, the Wireless 2350 also supports Advanced Encryption Security (AES) encryption. AES will replace 802.11's RC4-based encryption under the 802.11i specification. AES, the gold-standard encryption algorithm, provides maximum security for wireless network.

For user authentication, WPA adopts an authentication scheme through 802.1x. 802.1x provides a framework for user authentication and a key distribution management method.

802.1x consists of three main elements: an Authentication Server (typically a RADIUS server),

WPA-enabled router or AP (called Authenticator), and a WPA-enabled client (called Supplicant). 802.1x ensures only authorized users can access the network.

In enterprises, WPA will be used in conjunction with both a wireless router and authentication server. In a Small Office/Home Office (SOHO) environment, where there is no authentication server, users can use pre-shared key (PSK) mode in place of the authentication server. The Wireless 2350 offers you WPA running in PSK mode. The mutual authentication and improved encryption technology of WPA allows wireless communication to achieve greater security.

Automatic Rate Selection and Rate Scaling

In 802.11g, wireless network adapters and access points can transmit data at one of the following rates: 54, 48, 36, 24, 18, 12, 9, or 6 Mbps. In 802.11b, the data can be transmitted at a rate of 11, 5.5, 2, or 1 Mbps. As the distance between an adapter and access point increases or decreases, the data rate automatically changes. Other factors, like interference, also affect the data rate. The Wireless 2350 uses automatic rate selection and rate scaling to determine the most efficient rate of communication. Rate scaling maintains optimal communication between wireless clients and the WLAN.
