I'm starting to learn about wireless pentesting with BackTrack, and while learning how to find out the hidden SSID I wondered how could I connect to the wireless network after I discover the SSID. The book I'm studying does not cover that topic, only how to find the SSID.

I tried:

ifconfig wlan0 netmask up
iwconfig wlan0 essid "XXXX" channel X

but that doesn't work. Result in screenshot: enter image description here

  • Define "that doesn't work". (Are you sure this is an open access point with no WPA2 or WEP?) Also, in the future, please use copy&paste rather than a screenshot. – Celada Nov 25 '12 at 8:06
  • @Celada when I try to use the browser it behaves in the same way as a browser with no connection. I'm sure there is no WPA2 or WEP, and I don't know if it is the same thing as closed access, but I'm using the closed network option to hide the SSID. I used the screenshot because I'm doing this on another computer. – Ivan Lerner Nov 25 '12 at 8:25

    @IvanLerner you don't have any nameserver setup, default routes or anything else. You just connected at the physical layer but you don't have your IP settings configured correctly. – Ulrich Dangel Nov 25 '12 at 10:55
  • @UlrichDangel can you give some references or tell me how to do that if it is not a big deal? But I'd like something that really explains it, and not just a walkthrough on how to set it up. – Ivan Lerner Nov 25 '12 at 14:31

    I don't understand why you closed the question. It is just a question on how to connect to a network without any encryption at all using a hidden SSID. How can that be too specific? – Ivan Lerner Nov 26 '12 at 0:02
