wicd does not detect wireless networks

Hello all,

I have just switched to Squeeze (new install) and I am setting up my wireless internet connection. It doesn't work. Here is what I did.

I identified the wireless device with
# lspci -nn | grep Network
wireless device name is "Intel PRO/Wireless 3945"

I installed the firmware
# aptitude install firmware-iwlwifi wireless-tools

I checked the interface with
# iwconfig

wlan0 IEEE 802.11abg ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry long limit:7 RTS thrff Fragment thrff
Encryption keyff
Power Managementff

wicd was already installed

I changed the /etc/network/interfaces to contain only the following

# 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

So I had to exclude the lines
# The primary network interface
# allow-hotplug eth0
# iface eth0 inet dhcp

I reloaded DBus, started wicd daemon and last started wicd GUI with
# /etc/init.d/dbus reload
# /etc/init.d/wicd start
exit root
# wicd-client -n

But now in the wicd GUI,
1) there is no wireless network (and I know I should be able to see 3 at least)
2) in "General settings", "Networ interfaces", "Wireless interface" there is nothing (I would expect to find wlan0 no?)

of note: radiobutton is on (manually and from the command line), and I restarted the computer (twice because I still expected to see some kind of magic to happen...)
Any idea?

Hello all,

I reply to my own post. I found the, well it's more "a", solution. I just added wlan0 in "General settings", "Networ interfaces", "Wireless interface". And I can now detect the wireless networks around. Don't know yet if the connection works because I don't have access to these networks. I'll check that tomorrow.

Sorry for the previous post of little use, I still don't understand why I had to edit wicd through the GUI. If anyone had a command answer to this issue, I would be happy to know it.
