hello, this is my first post . I am hoping that you guys can help me with modifying iwconfig, i already have it unpacked and ready to manipulate in the source code in the terminal. I want to see if it is possible to modify it so that i could run iwconfig continuously and print its information at interval times. can anybody guide me into doing this? Thanks a lot.

Change the sleep to what you want. I think you'll find it a hell of a lot easier than hacking out a solution, though the same idea as above could work, though (And call me crazy) something tells me you're not quite at that stage yet

thanx, yes im a newbie. so do i just copy that code into what part of the code??? or is it pseudo-code? but yes, thats exactly what i wanna do

It's a command for the commandline, or a script, if you want. jamescondron's suggestion is that you do not modify the source code of the iwconfig program at all. Instead, compile and install it as is (if you don't have it already), open a terminal (xterm, konsole or such) and type in this script. It will run the iwconfig command every 5 seconds and print its output in that terminal window.

you guys are awesome! that worked. thank you very much. I have however, another problem . I just got a cisco 350 card from ebay, and it is supposed to work out of the box, but its just not doing it. There is not available driver in the cisco.com website, i however downloaded linux-acu-driver-v21.tar.gz but my card is still not up yet. any thoughts? when i first inserted the card nothing happened, neither when i did sudo pccardctl ident.

In theory, you should unpack the tar.gz archive, with the command

tar zvxf linux-acu-driver-v21.tar.gz

cd into the directory it will create (it will be called "linux") and carefully read the file there called "readme.txt". Then do what it says.

But I somehow doubt that you need this driver. It looks like it was made for older kernels, like 2.2 and 2.4. Which distribution are you running? You can see the version by typing

uname -a

in the commandline. From what I see on the net, the support for this card is already in the kernel. Let's just see quickly what you have. Could you post the output of the following commands (you need to be root to do that)
with the card inserted?

zcat /proc/config.gz | grep AIRO
lsmod | grep airo
dmesg | tail
uname -a
iwconfig
ifconfig

lsmod | grep airo doesnt do anything and
zcat /proc/config.gz | grep AIRO tells me theres no such directory

hello guys, i just turned on my computer and when i do iwconfig, my card doesnt show. i dont know what to try in order for my card to work. i know it is a 2.6 and that i dont need to install any drivers, i read in an online article that if i do "sudo dhclient", my card should work, but nothing is happening!

According to that paste of iwconfig, eth1 is your wireless card, it is connected to 3NC and you need to auth

oh yeah well thats my wireless card that comes with the computer, but i want to set up the cisco 350 in it, and it is not reading it. do i need to turn off my stock card in order for the other one to kick in??

Oh, got you; first things first- is your chipset supported? Have you installed the firmware for it? Are you sure the card is correctly physically installed?

i do not know if my chipset supports it. how do i check? firmware...i dont think so. im pretty sure i physically inserted it correctly. last night it was at least getting me some link quality and signal level.
