Wireless network security is very important in security, privacy and confidentiality of our data and resources. It requires the use of network resources through encryption keys of packets to achieve authentication or authorization of users. It is therefore very paramount to investigate the effects and performances of pre-shared keys and radius servers to improve user quality of service and experience in data management. In this work, wireless local area (WLAN) connections and security access were explored using roaming approach across access points with the help of ad-hoc Network and sharing internet access via ADSL router. WLAN packets were captured and analyzed with wire shack analyzer to detect and evaluate security measures for efficient control of access to multiple networks. The paper demonstrates the effectiveness and performance of WPA- PSK and WPA_RADIUS in terms of access security control in wireless networks.
