Hi, I can't exactly tell how to fix it but I know why this message occurs. This is because the wireless tools have their own version of Wireless Extention which is at the moment v16 and the drivers of your wireless card are always compiled against the Wireless Extentions of your kernel and this are (as of Kernel 2.4.21) WE v15. But you can get a patch for kernel 2.4.21 to get WE v16 at http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html but I don't know if they work with the Debian kernel.
I hope this helps a bit. -- Marcel Gschwandl <[EMAIL PROTECTED]> The day Microsoft invents something that doesn't suck is the day they start making vacuum cleaners. -- Ernst Jan Plugge
