WPA_supplicant trouble connecting client to AP

Hi Jouni,

>Which wpa_supplicant are you using?

I'm currently using wpa_supplicant v2.0-devel

This parameters I think represent that the frequency of the AP is
already fixed. This wpa_supplicant configuration file is parsed from a
generic wpa_supplicant configuration, this is done in this way in
OpenWRT; they launches hostapd which parses  this generic file and
calls wpa_supplicant with it.

I've followed your advice, and I have disabled the -B option and now I
get more output once I launch wpa_supplicant, which is this one
