I'm trying to connect via wifi but i keep getting this message: (I'm using NO interface)

SIOCSIFADDR: No such device

wlan0: ERROR while getting interface flags: No such device

wlan0: ERROR while getting interface flags: No such device

Bind socket to interface: No such device

Failed to bring up wlan0.

I've already edited the interfaces file on /etc/networks adding this line:

auto wlan0

iface wlan0 inet dhcp

and i cannot scan using "iwlist wlan0 scan"

How can I make this a Wi-Fi Client?

I'm using Debian GNU/Linux 6.0

wlan0 doesn't appear in the ifconfig -a output that is:

Does a wlan0 interface show up in ifconfig output? –  nodiscc Jan 9 '13 at 22:34
    
nope. it doesn't. Here's my ifconfig output: –  AAlvz Jan 11 '13 at 20:16
    
I've updated the question. –  AAlvz Jan 11 '13 at 20:18
    
If the link is down, you won't see it in plain old ifconfig. Try ifconfig -a. Also, you didn't indicate your exact wireless hardware (try lspci -nnvv) which is crucial to know anything about how to answer this question. We also need to know which version of Debian from /etc/issue file. Also, if you are needing WEP or WPA support, you should use NetworkManager; all other methods of using the wifi stack are spotty at best. –  ÃŁŁǫǛȉЖΦΤїҪ Jan 11 '13 at 20:28
