Configuring Security
Use the next sections to understand how to configure each type of security
on your wireless CN3 Computer.
The CN3 Computer provides three types of security for your wireless net-
work: Wi-Fi Protected Access 2 (WPA2/802.11i), WPA, and WEP.
802.1x should be referred to as an authentication method used for WPA
and WPA2. Another authentication method for WPA and WPA2 would be
the Pre-Shared Key (PSK).
By default, Funk security is enabled. You must use either Microsoft or
Funk security to implement your security solution. Go to page 130 for
more information.
Loading Certificates
If you choose to use Transport Layer Security (TLS) with WPA or 802.1x
security, you need to have a unique client certificate on the CN3 Computer
and a trusted root certificate authority (CA) certificate. If you choose to use
PEAP, you need to load a root CA certificate. You can use a third-party CA
to issue unique client certificates and a root certificate.
Wireless Network
Your wireless adapter (network interface card) connects to wireless net-
works of two types: infrastructure networks and ad-hoc networks.
• Infrastructure networks get you onto your corporate network and the
internet. Using the 802.11b/g infrastructure mode, the CN3 Computer
establishes a wireless connection to an access point, linking you to the
rest of the network.
• Ad-hoc networks are private networks shared between two or more cli-
ents, even with no access point.
If your CA is on your WLAN, select Start > Settings > the System tab > the
Certificates icon > the Root tab to view certificate details. To remove a cer-
tificate, press and hold a certificate, then select Delete.
