Wellenreiter

Wellenreiter is a wireless network discovery and auditing tool. Prism2, Lucent, and Cisco based cards are supported. It is one of the easiest to use linux wireless scanning tools available. No card configuration has to be done anymore. The whole look and feel is pretty self-explainatory. It can discover networks (BSS/IBSS), and detect ESSID broadcasting or non-broadcasting networks as well as their WEP capabilities and the manufacturer information automatically.
