Banging my head accessing my wifi

[Mathieu Malaterre <mathieu.malaterre@gmail.com>]

Hi there,

  I am trying -yet again- to access wifi from my debian/stable box. I
gave up on using NetworkManager  since it does not even scan or list
available networks.

  I added the following line to  /etc/network/interfaces:

# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp

+ iface wlan0 inet dhcp
+        wpa-ssid NEUF_XXXX
+        wpa-psk thepassword

Which should be started using:

$ sudo ifup wlan0

No DHCPOFFERS received.
No working leases in persistent database - sleeping.

Here is part of dmesg:

I am using a default debian installation with GNOME, what tool can use
to actually get anywhere (at least get informative debug info).

Thanks,
