Hi everybody.

I want to read the signal strength of my wireless card.
Can anybody tell me how?
I tried iwspy.
It gave me "command not found."

just use iwconfig:

Code:

chris@chris-laptop:/media/Data$ iwconfig 
lo        no wireless extensions.

eth0      no wireless extensions.

wmaster0  no wireless extensions.

Also, when I write this instruction "iwconfig"

It gives me "command not found"
