Every year the number of users of the global network Internet. Due to the rapid pace of development of portable technology is the most relevant method of Internet connection is a wireless connection. In a Wi-Fi network provides for the use of the access method to a common transmission medium CSMA/CA. The method is probabilistic in nature, which ing does not guarantee a successful message transmission in the case of high inten-zivnosti network traffic. For this reason, networks that use this access method, are ill-suited to address control tasks in real time. Some modification of the access algorithm CSMA/CA eliminate such disadvantages of Wi-Fi networks, such as: - inability to use such networks for solving control tasks in real time; -.the inability of priority service subscribers. In the article the results of researches of possibility of correction of the access method CSMA/CA by applying an intermediate driver in the stack of network drivers.
