Why i have wlan0 down?
Thanks in advance.
I think it's because it comes that way from the bios, but I could be
wrong. In the case of /etc/network/interfaces, you shouldn't need to
do anything special. If you want to run iwlist, or do something else
that requires the card to be up, then ifconfig up wlan0 should enable
wlan0. Someone else will have to help you as far as enabling it in gnome.

Is this a dual-boot system, with Windows being the other? If so, it may
be the case that the Win driver shuts down the wifi card, and not even
the BIOS can re-enable it. I had that problem on an Acer Travelmate a
while ago.
From memory, in Windows (mine happened with Vista...) check the Device
Manager -- Wifi Adapter -- Properties, somewhere there was an entry like
"windows is allowed to shut down this device to save power". Try and
disable that feature and make sure Wifi is enabled before you shutdown
Windows.
