wpa_supplicant to handle a connection to specific
SSID. I added the
runlevel in order to start it at the boot time.
I have this question however; Is it any program, script or even ncurses GUI to show me exact and live signal strength.
This is useful as it shows me if my location has poor reception or my ISP has low speed at each given time.
PS: I checked
iw and its family like
iwlist but they are not really what i want.
It is little known feature, but
Conky can be run in console mode with its variables describing network: http://conky.sourceforge.net/variables.html
You could edit any conkyrc and use
output_to_console variables to have conky render text in console.
Also you could try
wifi-menu (for network selection and control) and
wawemon (nice wifi graphs). Both aplications work on wpa_suplicant.
While you might prefer bare-bones solution,
wicd daemon has its own ncurses and cli interfaces.
Also aircrack-ng has
airmon, thought because those tools used for hacking, they might not fit your needs.
