Encrypting Wireless LAN Transmissions

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

your wireless transmissions. Choose one of the following:

Encrypting Wireless LAN Transmissions

Configure on the

CH6640E/CG6640E Required on Each Wireless Client

if all of your wireless clients

support Wi-Fi Protected Access

(WPA), recommending configuring

WPA on the CH6640E/CG6640E

If you use a local pre-shared key (WPA-PSK)

passphrase, you must configure the identical

passphrase on the CH6640E/CG6640E and on each

wireless client. Home and small-office settings typically

use a local passphrase.

Otherwise, configure WEP on the

CH6640E/CG6640E

You must configure the identical WEP key on the

CH6640E/CG6640E and on each wireless client.

If all of your wireless clients support WPA encryption, recommending 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, recommending purchasing client adapters that support WPA

encryption.
