tool for showing the wlan signal strength in real time

hi guys :>
is there any app around which is able to show the signal's strength of several access points in real time?
because i want to check where's the "peak" of the signal and finally where to attach the antenna

best regards

Re: tool for showing the wlan signal strength in real time

When I was still on WiFi I used iwconfig, cut, and some borrowed bash-fu to display the strength in dB. I can't quite test it, as I am not using a WiFi card anymore, but I remember it was something like the command at the end of my post. You will need to change ra0 to the name of your connection and -c11-23 to the spots where signal strength is displayed. The latter will be more challenging; I recommend just running iwconfig ra0|cut -c11-23 and changing the numbers until you get what you want.
while true;do clear;iwconfig ra0|cut -c11-23;sleep 1;done
