Comments/Problems:
For wlan I use NETGEAR WG111v3 (USB)
I installed Squeeze using the first two CD and wlan with no
protection; wlan worked in the installation;
after installation I was unable to setup wpa wlan connection using
Gnome; this was
my "/etc/network/interfaces" as written by the installer:
---------------------------------------------------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug wlan0
iface wlan0 inet dhcp
    # wireless-* options are implemented by the wireless-tools package
    wireless-mode managed
    wireless-essid NETGEAR
---------------------------------------------------------------------------------

I found that deleting the last lines makes things work:
---------------------------------------------------------------------------------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback
