OMPACT FLASH WLAN

The WLAN configuration with "setup" application is not yet available. The currently supported

WLAN cards are "EZ Connect" by SMC Networks and "Instant Wireless" by Linksys. For this

kind of Prism II/III based CF WLAN cards there are two different drivers.

4.3.1 H

OSTAP DRIVER

If your WLAN card firmware is 1.7.4, you have to use Hostap driver. It supports both client and

master modes. You can check the firmware version by inserting the card and entering

command "dmesg". If you see the following line among the latest ones, you have firmware

1.7.4:

eth1: Looks like an Intersil firmware version 1.7.4

To select Hostap driver enter the following command (ignore errors):

[root@wrap /]$ mv /etc/pcmcia/hostap_cs.conf.hermes

/etc/pcmcia/hostap_cs.conf

To use the master mode create the file "/etc/sysconfig/wlan" with one line "DISABLE=no", for

example with the following command:

[root@wrap /]$ echo DISABLE=no > /etc/sysconfig/wlan

To configure the master mode to use encryption, add following lines (replace examples with

your ESSID and encryption key, which can be also shorter for 40/64bit encryption) to the file

"/etc/sysconfig/wlan":

WEPKEY="0123456789abcdef0123456789"

ESSID="myessid"

To use client mode create the file "/etc/sysconfig/wlan" with one line "DISABLE=yes", for

example with the following command:

[root@wrap /]$ echo DISABLE=yes > /etc/sysconfig/wlan

In client mode you also have to configure client settings in the file

"/etc/sysconfig/network.pcmcia", see below.

4.3.2 H

ERMES DRIVER

You have to use Hermes driver if your WLAN card firmware is below 1.7.4. Hermes supports

only client modes.

To select Hermes driver enter command (ignore errors):

[root@wrap /]$ mv /etc/pcmcia/hostap_cs.conf

/etc/pcmcia/hostap_cs.conf.hermes

To configure WLAN to use DHCP, create the file "/etc/sysconfig/network.pcmcia" with one line

"DHCP=y", for example with the following command:

[root@wrap /]$ echo "DHCP=y" > /etc/sysconfig/network.pcmcia

To configure WLAN with static network settings, create the file

"/etc/sysconfig/network.pcmcia" similar to this example configuration:

DHCP=n

IPADDR="10.0.0.41"

NETMASK="255.255.255.0"

NETWORK="10.0.0.0"

BROADCAST="10.0.0.255"

GATEWAY="10.1.1.254"

SEARCH="local.net"
