Encrypting Wireless Lan Transmissions - Motorola surfboard sbg901 User Manual

Encrypting Wireless LAN Transmissions

To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your
wireless transmissions.
Use the Wireless 802.11b/g Privacy Page
Configure on the SBG901
If all of your wireless clients support
Wi-Fi Protected Access (WPA),
Motorola recommends configuring
WPA on the SBG901
Otherwise, configure WEP on
the SBG901
If all of your wireless clients support WPA encryption, Motorola recommends using WPA instead
of WEP because WPA:
•
Provides much stronger encryption and is more secure
•
Provides authentication to ensure that only authorized users 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, Motorola recommends purchasing client adapters that support WPA
encryption.

Required on Each Wireless Client
If you use a local pre-shared key (WPA-PSK) passphrase, you
must configure the identical passphrase to the SBG901 on
each wireless client. Home and small-office settings typically
use a local passphrase.
You must configure the identical WEP key to the SBG901 on
each wireless client.
