In order to configure wpa_supplicant to connect to a specific network: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf Have the file content look something like: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="network-name" psk="network-password" proto=RSN key_mgmt=WPA-PSK pairwise=CCMP TKIP ...


How about iwgetid? The iwgetid(8) man page says: iwgetid is used to find out the NWID, ESSID or AP/Cell Address of the wireless network that is currently used.


This may work: /sbin/iwconfig wlan0 | grep ESSID
