Here's what my > wpa_supplicant.conf looks like: I have as well the feeling that, when I was associated once and leaving the AP physically, I can't re-associate anymore, even not after a boot; I tried your hint about 'iwconfig eth0 essid off' but it does not improve the situation; I've now filed a bug report as https://docs.openmoko.org/trac/ticket/2045 with also a wpa_supplicant debug session; it tries to associate: Trying to associate with 00:04:e2:a1:76:0b (SSID='santaclara' freq=2442 MHz) ...
