While using the Atheros USB wireless network adapter, encrypting data can protect its privacy as it is transmitted through the wireless network.
This is because the WEP keys of all devices that are to communicate with each other must match. Authentication Process Enabling EAP on the access point and configuring the USB device to LEAP, EAP-TLS, PEAP (EAP-GTC), or PEAP (EAP-MSCHAP V2) authentication to the network occurs in the following sequence: 1. The client associates to an access point and begins authentication. 2.
