Chapter 1 Introduction Thank you for using the Wireless LAN module. This high-speed Wireless LAN module provides you with an innovative wireless networking solution for your embedded system. The module is easy to set up and use. With this innovative wireless technology, you can share files and printers on the network—without inconvenient wires! Now you can carry the LAN in your pocket! This module is designed for 1. Wireless LAN Printer Server 2. Wireless LAN Ethernet Adapter 3.
Wireless LAN card user manual LAN Modes Wireless LANs can be configured in one of two ways: Ad-hoc Networking Also known as a peer-to-peer network, an ad-hoc network is one that allows all workstations and computers in the network to act as servers to all other users on the network. Users on the network can share files, print to a shared printer, and access the Internet with a shared modem.
Chapter 2 Hardware installation This chapter covers how to installing the wireless LAN module in your embedded system. Hardware description The Wireless LAN Module has a standard PCMCIA 68-pin connector for attaching to the PCMCIA port of embedded system. And this module has MMCX connector to connect to external antenna. Status LEDs The following table describes the meaning of the LEDs: LED MEANING PWR Indicates that the Card is powered on. LINK Indicates link status. It is normally blinking.
Wireless LAN card user manual Installation Procedure 1. Unpack the tgz file by typing the following line at the shell prompt, (assuming the shell prompt is >). >gzip -cd wlan-ng-0.1.6.tgz | tar xvf - 2. Configure and install wlan v0.1.6. Be sure to configure the build as Station (STA)—do not choose Access Point (AP) because there is no firmware available that supports the AP function. >cd wlan-ng-0.1.6 >make config >make all >make install 3. Edit /etc/pcmcia/wlan-ng.
—Installation for Embedded Linux System When Linux is booting up, you will hear two high pitch beeps. This means that the driver has been loaded successfully. If you want to know if the card has connected to an access point, see if the red ACT LED on the card is illuminated. When the ACT LED stops blinking, it means the card/station has been connected to an access point.
Chapter 4 Using the Wireless Utility This module also come with a wireless utility, following describe how to use the utility. Configuration Utility The following table describes the configuration utility: State: displays the connection status. Current Channel: displays the channel. Current Tx Rate: displays the wireless bandwidth in megabits per second. Throughput: displays the transfer and receive rates in bytes per second.
—Using the Wireless Utility The Encryption window enables you to create an encryption scheme for Wireless LAN transmissions. Enter a passphrase and press Generate to automatically generate a 64- or 128bit key (selected from the WEP dropdown menu in the Configuration screen). You can also manually enter a set of values for each key. Note: 128-bit encryption requires more system resources than 64-bit encryption. Use 64-bit encryption for better performance.
Appendix A Troubleshooting Q&A These guidelines give you tips to deal with some problems you may encounter while using the Wireless LAN module. Question: Can not connect to one of the clients in the network. Answer: First of all, make sure that all clients are up and running with a green Wireless Utility icon. And please check your TCP/IP setup is correct for your network.
