Wireless EtherScope discovers whether infrastructure and client devices are employing the appropriate authentication mechanism. EAP (Extensible Authentication Protocol) authentication is tested and monitored using Wireless EtherScope's login test tool. Using Wireless EtherScope, force a wireless client to disassociate from an access point, and monitor the client and access point EAP exchange as the client re-authenticates on the network. Discover if, where, and when the EAP authentication process breaks down.
