Hi Bastian, thanks for replying. The line I referred to is in wpa_supplicant.sh line 167.
Then, according to your explanation, in the script wpa_supplicant.sh line 167, that means the variable fixed will have a value of "fixed_freq=1" right? I guess this option is only enabled on the sta mode, doesn't it? I ask this, because I´m trying to understand how the client knows the AP channel or frequency... thanks again 2013/5/16 Bastian Bittorf <[email protected]>: > * Francisco Cuesta <[email protected]> [16.05.2013 18:32]: >> Thanks for replying Bastian, >> >> Do you know the meaning of the ${fixed:+"fixed_freq=1"} ??
