I didn't know that. Thanks.

I was trying with just the things installed in the basic system. I'm not 
on a network, but just want to connect to the internet, using my laptop, 
through the router on my PC. I now have wireless tools installed and 
have remembered that I've never configured a card or usb device--just 
pcmcia cards--and I'm confusing some of the commands from the pcmcia 
wrapper that I used to use.

Right now I'm caught in the "Twilight Zone" of CLFS and host system. 
Can't check the things I want to in chroot environment. With <iwconfig 
wlan0 essid any> I got no messages so I assume OK. However, with 
<iwconfig wlan0 mode 'Ad Hoc'> I got the message that it didn't work 
because the device was in use or busy. I couldn't ping my DNS server and 
dhcpcd failed when I tried to restart the network. However when I ran 
<iwlist wlan0 scan> I got all information I ever wanted to know about my 
router. Something's working. I just can't figure out how to use it.

I'm out of my CLFS system right now, but I think I can pass ESSID and 
MODE in the udev rule.

Thanks for you help so far. I can't find my book "Linux Unwired," so any 
further hints would be great.

I've never used this one. Maybe a try is in order.

Thanks.
