Laptop if and iw config results

[Karl Larsen]

I went to my Sony laptop with F7 on it and got the results of doing a 
ifconfig and a iwconfig. As you see the iwconfig results has more 
information. In fact the ifconfig data may actually be false.

    I wonder why iwconfig says there is no wireless extentions to wifi.0?
