Honeypot and Misassociation attacks
Normally, when a wireless client such as a laptop is turned on, it will probe for networks it has previously connected to. These networks are stored in a list called the Preferred Network List (PNL) on Windows-based systems. Also, along with this list, the wireless client will display any networks available in its range.
