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
to encrypt your transmitted data. Choose
one
of:
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
only
authorized users can log on 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:

Required On Each Wireless Client
If all of your wireless clients support Wi-Fi
Protected Access (
WPA
), we recommend you
follow
Configuring WPA on the VT2500
If you use a local pre-shared key (WPA-PSK) passphrase, you
must configure the identical passphrase to the
VT2500
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.
Otherwise, perform
If you need to restore the
wireless defaults, click Reset Security Defaults.
You must configure each wireless client with the
VT2500
’s WEP
key (must be identical)
