(Wired Equivalent Privacy) mode and signal strength.

Lucent/Orinoco Registry Encryption/DecryptionLucent Orinoco Client Manager stores WEP keys in the Windows registry under a certain encryption/obfuscation. This wi-fi tool can be used to encrypt WEP keys into a registry value or to decrypt registy values into WEP keys.

APTools
APTools is a utility that queries ARP (Address Resolution Protocol)
Tables and Content-Addressable Memory (CAM) for MAC Address ranges associated with 802.11b Access Points. It will also utilize Cisco Discovery Protocol (CDP) if available. If an Access Point that is web managed is identified, the security configuration of the Access Point is audited via HTML parsing.
