1. A method of capturing and selectively filtering data frames transmitted between stations in a wireless communications network, said method comprising steps of:
- (a) establishing a direct wireless logical connection with the wireless communications network;
(b) receiving wirelessly, in real-time, data frames transmitted in the wireless communications network;
(c) receiving frame attribute parameters inputted by a user through a user interface system;
(d) comparing frame attributes of one of the received data frames with said user-inputted flame attribute parameters; and
(e) displaying to the user and/or storing in a memory storage device, the data frames that match with the user-inputted frame attribute parameters.

Abstract
A method and apparatus provides for wirelessly monitoring data packets or frames transmitted in a wireless LAN, that permits a user to selectively filter out unwanted ones of the data packets or frames with respect to the source and destination hardware addresses, and to the frame type and subtypes.

13. A network monitoring apparatus for capturing and selectively filtering data frames transmitted between stations in a wireless communications network, the apparatus comprising:
-
a wireless network interface device for establishing a logical connection with a wireless communications network and capturing a plurality of data frames transmitted though said network;
a user interface system comprising input and output devices for enabling a user to input and obtain information associated with said plurality of captured data frames;
a memory storage device for storing said plurality of captured data frames from said wireless communications network;
a processor unit electronically connected to said network interface device, said user interface system, and said memory storage device being programmed to execute a routine comprising the steps of;
(a) establishing a direct wireless logical connection with the wireless communications network via said network interface device;
(b) receiving wirelessly, in real-time, data frames transmitted in the wireless communications network via said direct wireless logical connection;
(c) receiving one or more frame attribute parameters inputted by a user through the user interface system;
(d) comparing frame attributes of one of the received data frames with said user-inputted frame attribute parameters; and
(e) displaying to the user and/or storing in the memory storage device, the data frames that match positively with the user-inputted frame attribute parameters.
