802.1x se t t i n g /Ce r t i F i Cat i o n
The EAP authentication protocols supported by this
adapter require that settings be consistent with the wireless access
points or routers that the adapter is intended to connect.
These protocols are similar and easier to use than
TLS (below) in that they specify a stand-alone authentication protocol
to be used within an encrypted tunnel. TTLS supports any protocol
within its tunnel, including CHAP, MS-CHAP, MS-CHAPv2, PAP and
EAP-MD5. PEAP species that an EAP-compliant authentication
protocol be used; this adapter supports EAP-MSCHAP v2, EAP-TLS/
Smart Card and Generic Token Card. The client certicate is optional.
This is the most secure of the EAP protocols, but
isn’t easy to use: It requires that digital certicates be exchanged in
