If you use WEP like me, here is how to solve the problem without using or installing wicd.

Firstly, test that it will work by first stopping the network manager service:

/etc/init.d/network-manager stop

This is to verify that you are running independently of network-manager.

Then edit /etc/network/interfaces like this:

iface wlan0 inet dhcp
pre-up wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf &
post-down kill -9 `pidof wpa_supplicant`
auto wlan0

Depending on your wifi card, you may need to use the -D option for wpa_supplicant.

Then, edit /etc/wpa_supplicant.conf (this will probably be created as a new file) and make it look like this:

# Static WEP keys

ctrl_interface=/var/run/wpa_supplicant

network={
	ssid="YOUR_SSID"
	key_mgmt=NONE
	wep_key0=YOUR_WEP_KEY
	wep_tx_keyidx=0
}

(The above code was modified from examples in /usr/share/doc/wpa_supplicant/examples)

Then restart networking:

/etc/init.d/networking restart

Verify that your wlan0 interface has an IP and you can ping other hosts on your LAN. If it works you may safely remove network-manager via apt-get like i did.
