I think a line like iface wlan0 inet dhcp ...or something similar is missing here. > wpa-ssid "[my network's name]" > wpa-spk "...and its password..." Not that it matters syntax wise, but I typically don't indent the lines "iface ..." which precede the interface details and treat the "auto" lines as "main" items, like so: auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp wpa-ssid "[my network's name]" wpa-spk "...and its password..." That's also the convention in the man page examples, see man(5) interfaces. Cheers -- t
