Thank you for your reply.

There is no iface command: I was not clear enough and just pasted the
/etc/network/interfaces iface stanza for my wireless. So

iface wlan0 inet dhcp
  wireless-essid XXXX
  wireless-key YYYY

is how my wlan0 interface is configured within /etc/network/interfaces.

I did not really make changes to the system. I did install some
SELinux packages, but right after I purged for various reasons.

How do I turn on the interface, if after my attempts (with ifup,
iwconfig, network-manager, ...) I still do not get scan results? (I
wonder whether I am even able to scan, or just do not find networks)

Thank you

Francesco
