Encrypting Wireless LAN Transmissions 

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

If all of your wireless clients 
support Wi-Fi Protected Access 
(WPA), Motorola recommends 
configuring WPA on the SBG901 

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.  

Otherwise, configure WEP on the 
SBG901 

You must configure the identical WEP key to the 
SBG901 on each wireless client. 

 

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.
