PCMCIA Cards Integration
Wireless LAN PC Cards
First do the appropriate PCMCIA network configuration. Additionally, the
configuration of the wireless driver is done in the following file:
/etc/pcmcia/wireless.opts
For instance, to configure the network name as MyPrivateNet , and the WEP encryption
key as secu1 , the following settings could be added to the default “*,*,*,*)" entry :
NOTE:
The "s:" prefix in the KEY line indicates that the key is an ASCII string, as opposed
to hex digits. Five ASCII characters or ten hexadecimal digits could be entered for WEP 64-
bit (also known as 40-bit) and 13 ASCII characters or 26 hexadecimal digits could be entered
for WEP 128-bit (also known as 104-bit). Any ascii characters will be accepted if it starts
with "s:" otherwise only characters between [0-9,a-f] will be accepted. Check your PCMCIA
card specifications.
There is a generic sample in the end of the wireless.opts file that explains all possible
settings. For more details in wireless configuration, search for manpage iwconfig on the
Internet. The parameters in wireless.opts are used by the iwconfig utility. After changing
any of the parameters, run “ cardctl eject ” followed by cardctl insert to load the new
settings. Also, run saveconf to save the new settings to flash. iwconfig eth1 shows the
basic wireless parameters set in eth1 . iwlist allows to list frequencies, bit-rates,
encryption, etc. The usage is:
iwlist eth1 frequency
iwlist eth1 channel
iwlist eth1 ap
iwlist eth1 accesspoints
iwlist eth1 bitrate
iwlist eth1 rate
iwlist eth1 encryption
iwlist eth1 key
iwlist eth1 power
iwlist eth1 txpower
iwlist eth1 retry
