Hi Mike--

I was trying to look for some data about the price differences between
40-bit and 128-bit Aironet cards, but I can't find anything now. I
don't have any data to refute your assertion that there's no difference
with respect to security.
If there were 802.11b cards that didn't have WEP at all (are there any
still?) would you advocate getting those over 40-bit encryption?

Errr...no, I didn't write the code. What I meant was that anybody can
put a set of commands to configure a network interface into /etc/
start_if.${name_of_interface} and the commands will get automatically
run by /etc/{rc.network,pccard_ether} as appropriate when they bring
that network interface up. Sorry for being unclear!
Mine is something like:
ifconfig an0 ssid 'SSID' wepmode on weptxkey 1 \
wepkey 1:0x112233445566778899aabbccdd
ifconfig(8) can do most things that wicontrol and ancontrol can do, at
least with respect to setting WEP keys, frequency selection, and so on.
Cheers,
Bruce.
