Introduction

The Cisco Aironet 340 Series Base Stations BSE342 and BSM342 (collectively referred to as Base Stations or BSx) provide home users and small offices with wireless connectivity to an intranet or the Internet. The Base Station, with an Ethernet RJ-45 port, can be connected to the Internet by digital subscriber line (DSL) or cable modem. The BSM342 is equipped with an integrated 56k v.90 dialup modem that enables multiple computers to access the Internet through one dialup connection.

You can quickly install and configure the Base Station with an easy-to-use graphical interface. The Base Station Client Utility (BSCU), included with the system and for use with Cisco Aironet client adapters, provides Windows clients an easy-to-use tool to perform these tasks. Linux and MacOS clients can quickly and easily configure the Base Station via Telnet or HTTP connections.

The BSE342 and BSM342 have no console port with which to make a direct cable connection. The default settings allow a wireless client PC to associate with the Base Station, from which point you can make a connection through the BSCU, a web browser, or a Telnet client without need of a wired connection.

Prerequisites

Requirements

Before you perform the tasks described in this document, use these procedures to install the Client Adapter:

You should also have the BSCU installed on the client PC (follow the steps detailed in the Install the BSCU section). If you plan to configure the Base Station from a Linux or MacOS client, you must be familiar with web browsers or Telnet.

Components Used

This document is applicable to BSE342 and BSM342 Base Stations that run any version of firmware.

While it is possible to use the Cisco Aironet BSx342 Base Station with many different wireless client platforms, currently the BSCU is supported only on platforms that run Microsoft Windows 95, 98, 2000, ME, and XP. Linux and MacOS clients must use a web browser or Telnet client to configure the Base Station through HTTP or Telnet.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Product Descriptions and Usage

BSE342

The Cisco Aironet BSE342 Base Station has a 10/100 BaseT Ethernet interface to connect to a wired network. The BSE342 can use Point-to-Point Protocol (PPP) over Ethernet (PPPoE), a protocol frequently required by Internet Service Providers (ISPs) for connection of a home network to the Internet through a DSL or cable modem.

BSM342

The BSM342 possesses the capabilities of the BSE342, and also incorporates a v.90 modem to allow dialup modem connection to an ISP.

Operating Modes and Descriptions

There are three operating modes configurable for the BSE342: Cable or DSL modem, Access Point, or PPPoE. The BSM342 has one additional mode: Dialup.

  • Cable/DSL modem mode allows the Base Station to connect to an ISP and the Internet through a cable or DSL modem.

  • PPP-over-Ethernet mode is used when your ISP uses PPP through a cable or DSL modem.

  • Access Point mode supports a standalone wireless network or connects to an internal LAN for wireless access. This configuration allows wireless terminals to access local LAN resources such as printers and servers.

  • Dial-up mode connects the Base Station to a telephone line and uses the internal modem to communicate with an ISP.

Configuration Through the Base Station Client Utility

Configuration of the Base Station through the BSCU involves these steps:

  1. Install the BSCU

  2. Configure the Client

  3. Configure the Base Station

Install the BSCU

Follow these steps to install the BSCU:

  1. Insert client radio card.

  2. If the Base Station Connection Status (BSCS) utility is installed on the PC, right-click the telephone icon in the system tray and select Exit prior to installation of the BSCU.

  3. Put the CD in CD-ROM drive of the computer to be used to configure the Base Station.

  4. Use Windows Explorer to display the contents of the CD.

  5. Double-click the BSCU folder to display it.

  6. Double-click the setup.exe file. The installation wizard appears.

  7. Follow the steps provided by the installation wizard.

  8. When requested by the installation wizard, select Talk To A Base Station To Access The Internet.

  9. Check the Launch Base Station Client Utility entry box and click Finish to start the utility.

Configure the Client and Associate to the Base Station

The Base Station does not have a console port. For initial configuration with the BSCU it is therefore necessary to connect to the Base Station through the radio link. In order to accomplish this, you must configure the client.

The Base Station has a factory default setting for Service Set Identifier (SSID) of tsunami. The SSID is used to identify clients that can associate to the Base Station. Set the SSID on the client to tsunami. Refer to Configuring the Client Adapter for additional client configuration information.

Follow these steps to configure the client and associate it to the base station:

  1. From the Base Station Client Utility menu bar, choose Client.

  2. Choose Edit Client Properties as shown in Figure 1.

    Figure 1 - Menu Selection

  3. Ensure that the SSID is set to the default tsunami.

    The Computer Name value defaults to the name configured in the Windows operating system. This name must be unique on the wireless network.

    Note: A change to the Computer Name setting can cause other network programs on the PC to be inoperable and your PC login password to be unrecognized. Use caution when you change this setting.

  4. Verify that the checkbox marked Enable Encryption (WEP) is unchecked.

  5. Click OK.

If the client fails at this point to associate with the Base Station, you must reset the Base Station to its default settings. Refer to Setting Defaults with the Reset Button.

The reset button is in a small hole on the back panel of the Base Station and is used to reset the Base Station parameters to the default values.

To activate the reset button, complete these steps:

  1. Insert a straightened paper clip into the small hole and press.

  2. Remove the paper clip.

  3. The Status LED blinks amber to show the Base Station has these default parameter values:

    Radio Network Name tsunami
    WEP Encryption Key 3031323334353637383930313233
    Network Type Infrastructure
    Data Rate Auto
    Encryption Enabled
    Authentication Type Open
    Encryption 128-bit Encryption
    Association Mixed Cells Allowed

    The Base Station sends these settings if you click OK. Click Edit Base Station Settings to make changes to the Base Station.

Configure the Base Station

Once the BSCU shows that the wireless client is associated with the Base Station, you can proceed with configuration.

netparms.gif

The SSID (Set Service Identifier) identifies the radio network of the Base Station and must be used by all wireless devices that communicate with the Base Station. To change this value, enter a new name in the entry box. You can enter from 1 to 32 ASCII characters.

WEP Encryption Key Entry Method selects the encryption key entry method. To changes this value, click either Hexadecimal (0-9, A-F), or ASCII Text.

The WEP Encryption Key provides security with 128-bit encryption. The encryption key must be set up exactly the same on all wireless devices and the Base Station. This entry is only available on client radio cards that support 128-bit WEP. Allowable entries in this field depend on the key entry method chosen. For ASCII entry, 1 to 13 ASCII characters can be used. If hexadecimal entry has been chosen, 1 to 26 hexadecimal characters (0-9, AF) may be used.

The Enable Encryption (WEP) checkbox enables or disables the use of 128-bit encryption. Click the box to change the setting.

Note: The SSID and WEP Encryption Key settings in all wireless client PCs must exactly match the settings in the Base Station. If you change these parameters in the Base Station, use the BSCU in all the other wireless PCs to reconfigure their client cards to match the new settings.

Once you have configured the network parameters, click the button labeled Next.
