Installation for Embedded Linux System
Following is a example to install the module to a embedded Linux system.
installation for Linux
Follow the steps below to install the Wireless LAN card drivers (wlan-ng v0.1.6) for Linux.
Before Installing the Linux Drivers
Before you install the Linux wlan-ng v0.1.6 drivers, you need the PCMCIA module source code. If you do not
have the source code, you can get it from the following URL:
ftp://hyper.stanford.edu/pub/pcmcia
After you have rebuilt and installed the PCMCIA module, edit /etc/pcmcia/network.opts to enable DHCP. In the
DHCP setup, you can leave the fields empty. If there is no DHCP server on your network, you might have to
disable DHCP to use a static IP and then fill the fields in /etc/pcmcia/network.opts.
In Linux there is an 802.11b Access Point with which the station can be associated.
