Encrypting Wireless LAN Transmissions

To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless transmissions.

Use the Wireless > SECURITY — basic Page to encrypt your transmitted data. Choose one of:

Configure on the SBG900

If all of your wireless clients support Wi-Fi Protected Access (WPA), we recommend Configuring WPA on the SBG900

Otherwise, perform Configuring WEP on the SBG900

Required On Each Wireless Client

If you use a local pre-shared key (WPA-PSK) passphrase, you must configure the identical passphrase to the SBG900 on each wireless client. Home and small-office settings typically use a local passphrase.

Configuring a RADIUS server requires specialized knowledge that is beyond the scope of this guide. For more information, contact your network administrator.

You must configure the identical WEP key to the SBG900 on each wireless client.

If all of your wireless clients support WPA encryption, we recommend using WPA instead of WEP because WPA:

•

•

•

•

•

Provides much stronger encryption and is more secure

Provides authentication to ensure that authorized users only can log in to your WLAN

Is much easier to configure

Uses a standard algorithm on all compliant products to generate a key from a textual passphrase

Will be incorporated into the new IEEE 802.11i wireless networking standard

For new wireless LANs, we recommend purchasing client adapters that support WPA, such as the Motorola Wireless Notebook Adapter WN825G, Wireless PCI Adapter WPCI810G, and Wireless USB Adapter WU830G. For more information about the benefits of WPA, see the Wi-Fi Protected Access Web page: http://www.wifialliance.org/OpenSection/protected_access.asp.
