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. Choose one:
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.

Encrypting Wireless LAN Transmissions
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.
