[PROBLEM] Connecting to hidden wifi

[deHakkelaar]

If you know the SSID (WiFi network name) and password, you can connect if put below 2 lines in "/etc/network/interfaces":
wpa-ssid <WIFI_NETWORK_NAME>
wpa-psk <PASSWORD>
(This is assuming your using WPA for security)

If you dont know the SSID, you will really need to unhide your WiFi and do a discovery.
For that you can use the 'xbian-config' command.
