I am using latest stable Debian build and trying to follow this tutorial.
/etc/network/interfaces has anything wifi related, currently:
auto lo iface lo inet loopback auto wlan0 iface wlan0 inet dhcp wpa-ssid myrealssid wpa-psk sonelongpassphrasereturnedbywpa_passphrase
service networking restart quietly takes more than few minutes to complete, without output or success.
iwlist scan shows real wifi access points so the device seems to be working.
How do I go about troubleshooting?
