54 CHAPTER 5: ROUTER CONFIGURATION
Profile Support for NICs
You may save your wireless settings here by clicking Save Profile. Please
choose Save to Disk option when a dialog box opens. Thus, you may save
your wireless settings to an external file and later on use this file to import
the settings with supported 3Com Wireless Network Cards.
Encryption When setting up wireless networks, it is important to remember that with
encryption disabled, anyone with a Wireless PC can eavesdrop on your
network. 3Com recommends that you get the network working with
encryption disabled first and then enable it as the last step. This will
simplify setting up your network.
The Router supports the following types of encryption:
■ WPA/WPA2/Mixed WPA WPA2 — Wi-Fi Protected Access (WPA) is a
subset of the IEEE 802.11i standard. Both WPA and WPA2 use
Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC)
and IEEE 802.11x. In addition to TKIP, WPA2 also uses Advanced
Encryption Standard (AES). The mixed mode will let you choose the
encryption mechanism interchangeably with either TKIP or AES.
■ WEP — Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit
encryption method with user configurable fixed keys.
■ WPA+Radius/WPA2+Radius/Mixed WPA WPA2 +Radius features using
of a RADIUS server with the pre-shared key authentication method.
(This should only be used when a RADIUS server is connected to the
Router).
WPA and WPA2 provides a higher level of security, provided by its longer
key and dynamic changes made to the key over time. 3Com recommends
that you use WPA with any clients which support it.
If you enable encryption on the Router, you must reconfigure your
wireless PCs to use exactly the same Encryption Type and Keys otherwise
the devices will not understand each other.
The encryption methods used by the Router secure data transmitted
through wireless communications between the Router and its wireless
clients. Enabling encryption has no security effect on data transmitted
through wired (Ethernet) connections or through your connections to the
Internet.
