I need to connect to a hidden network without password with wpa_supplicant:

iwlist <interface> scan output:

What is the wpa_supplicant configuration file needed to connect to this network?


Wrong guess:

network={
    ssid=""
    bssid=11:22:33:44:55:66
 }

According to Wiki-Archlinux you should add scan_ssid=1 to your wpa_supplicant configuration file:

Tip: To configure a network block to a hidden wireless SSID, which by definition will not turn up in a regular scan, the option scan_ssid=1 has to be defined in the network block.

to connect to an open network, you need to add the key_mgmt=NONE option to your wpa_supplicant configuration file :

network={
        ssid=""
        bssid=11:22:33:44:55:66
        scan_ssid=1
        key_mgmt=NONE
}

  • This solution does not work for me (wrong conf file).
