WPA Enterprise

WPA Enterprise features WPA security used in coordination with a RADIUS server. (This should only be used 
when a RADIUS server is connected to the Router.) WPA Enterprise offers two authentication methods, EAP-
TLS and PEAP, as well as two encryption methods, TKIP and AES, with dynamic encryption keys.

Authentication

 - Select the authentication method your network is using, 

EAP-TLS

 or 

PEAP

.

EAP-TLS

If you selected EAP-TLS, enter the login name of your wireless network in the
