I have a headless Debian machine, with a Wifi dongle connected. I used to hide the Wifi AP, but now I can't.
If I unhide it, some lines in the /etc/network/interfaces will allow me to connect:
auto wlan0 iface wlan0 inet dhcp wpa-ssid <name> wpa-psk <hex/raw pwd>
If I hide the AP, add this line, then restart the interface, it won't work (DHCP gets no IP):
I've not found official documentation about the /etc/network/interfaces config.
What can I do now?
