Wireless network cards, adapters, and access points can be configured as: Ad hoc for departmental, or enterprise LANs •...
Network Configuration Network Topologies Ad Hoc Wireless LAN (no AP or Bridge) An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel.
Network Topologies Infrastructure Wireless LAN The access point also provides access to a wired LAN for wireless workstations. An integrated wired/wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN.
Network Configuration Infrastructure Wireless LAN for Roaming Wireless PCs The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point.
Page 43
Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All SMC wireless network cards and adapters and SMC2552W-G wireless access points within a specific ESS must be configured with the same SSID.
Point SMC2552W-G offers a variety of management options, including a web-based interface, a direct connection to the console port, or using SNMP software such as SMC’s EliteView. The initial configuration steps can be made through the web browser interface using the Setup Wizard (page 4-4). The access point requests an IP address via DHCP by default.

System Configuration Authentication Wireless clients can be authenticated for network access by checking their MAC address against the local database configured on the access point, or by looking up their MAC addresses on a RADIUS server. The 802.1x protocol can also be configured to check other user credentials such as a user name and password.
Page 67
Advanced Configuration MAC Authentication – You can configure a list of the MAC addresses for wireless clients that are authorized to access the network. This provides a basic level of authentication for wireless clients attempting to gain access to the network. A database of authorized MAC addresses can be stored locally on the SMC2552W-G or remotely on a central RADIUS server.
Page 68
System Configuration • MAC Authentication Settings: Enters specified MAC addresses and permissions into the local MAC database. MAC Address: Physical address of a client. Enter six pairs of hexadecimal digits separated by hyphens; for example, 00-90-D1-12-AB-89. Permission: Select Allow to permit access or Deny to block access.
Page 69
Advanced Configuration The 802.1x EAP packets are also used to pass dynamic unicast session keys and static broadcast keys to wireless clients. Session keys are unique to each client and are used to encrypt and correlate traffic passing between a specific client and the access point.
Page 70
System Configuration • Session Key Refresh Rate: The interval at which the access point refreshes unicast session keys for associated clients. (Range: 0-1440 minutes; Default: 0 means disabled) • 802.1x Re-authentication Refresh Rate: The time period after which a connected client must be re-authenticated. During the re-authentication process of verifying the client’s credentials on the RADIUS server, the client remains connected the network.

System Configuration Filter Control The access point can employ VLAN ID and network traffic frame filtering to control access to network resources and increase security. Native VLAN ID – The VLAN ID assigned to wireless clients that are not assigned to a specific VLAN by RADIUS server configuration.
Page 75
Advanced Configuration VLAN IDs can be mapped to specific wireless clients, allowing users to remain within the same VLAN as they move around a campus site. This feature can also be used to control access to network resources from wireless clients, thereby improving security.
Page 76
System Configuration When VLAN filtering is enabled, the access point must also have 802.1x authentication enabled and a RADIUS server configured. Wireless clients must also support 802.1x client software to be assigned to a specific VLAN. When VLAN filtering is disabled, the access point ignores the VLAN tags on any received frames.

System Configuration Radio Interface The IEEE 802.11b and 802.11g interface includes configuration options for radio signal characteristics and wireless security features. The access point can operate in three modes, IEEE 802.11b only, 802.11g only, or a mixed 802.11b/g mode. Also note that 802.11g is backward compatible with 802.11b.
Radio Interface Radio Settings (802.11g) The IEEE 802.11g standard operates within the 2.4 GHz band at up to 54 Mbps. Also note that because the IEEE 802.11g standard is an extension of the IEEE 802.11b standard, it allows clients with 802.11b wireless network cards to associate to an 802.11g access point.
Page 96
System Configuration Radio Channel – The radio channel that the access point uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least four channels apart to avoid interference with each other. For example, in the United States you can deploy up to four access points in the same area (e.g., channels 1, 6, 11).
Page 97
Radio Interface interfere with the operation of other radio devices in the service area. (Options: 100%, 50%, 25%, 12%, minimum; Default: 100%) Maximum Station Data Rate – The maximum data rate at which a client can connect to the access point. The maximum transmission distance is affected by the data rate.

System Configuration The security mechanisms that may be employed depend on the level of security required, the network and management resources available, and the software support provided on wireless clients. A summary of wireless security considerations is listed in the following table. Security Client Implementation Considerations...
Page 103
Radio Interface Wired Equivalent Privacy (WEP) WEP provides a basic level of security, preventing unauthorized access to the network and encrypting data transmitted between wireless clients and the access point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric strings) that are manually distributed to all clients that want to use the network.
Page 104
System Configuration Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent Privacy (WEP) on the access point to prevent unauthorized access to the network. If you choose to use WEP shared keys instead of an open system, be sure to define at least one static WEP key for user authentication and data encryption.

System Configuration Wi-Fi Protected Access (WPA) WPA employs a combination of several technologies to provide an enhanced security solution for 802.11 wireless networks. The SMC2552W-G supports the following WPA components and features: IEEE 802.1x and the Extensible Authentication Protocol (EAP): WPA employs 802.1x as its basic framework for user authentication and dynamic key management.
Page 109
Radio Interface prevents users from accidentally joining a rogue network. Only when a RADIUS server has authenticated a user’s credentials will encryption keys be sent to the access point and client.

Troubleshooting Maximum Distance Table Important Notice Maximum distances posted below are actual tested distance thresholds. However, there are many variables such as barrier composition and construction and local environmental interference that may impact your actual distances and cause you to experience distance thresholds far lower than those posted below.
Appendix B Cables and Pinouts Twisted-Pair Cable Assignments Caution: DO NOT plug a phone jack connector into the RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards. For 10/100BASE-TX connections, a twisted-pair cable must have two pairs of wires.
Cables and Pinouts 10/100BASE-TX Pin Assignments Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100-ohm Category 3 or better cable for 10 Mbps connections, or 100-ohm Category 5 or better cable for 100 Mbps connections. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
Twisted-Pair Cable Assignments Straight-Through Wiring Because the 10/100 Mbps port on the access point uses an MDI pin configuration, you must use “straight-through” cable for network connections to hubs or switches that only have MDI-X ports. However, if the device to which you are connecting supports auto-MDIX operation, you can use either “straight-through”...
Cables and Pinouts Console Port Pin Assignments The DB-9 DCE serial port on the front panel of the SMC2552W-G is used to connect to the access point for out-of-band console configuration. The command-line configuration program can be accessed from a terminal, or a PC running a terminal emulation program.
