Establishing Security for Your Wireless LAN
To prevent unauthorized viewing of data transmitted over your WLAN, you must encrypt your wireless
transmissions.
If all of your wireless clients support WPA encryption, we recommend using WPA instead of WEP. The benefits of
using WPA:
• Provides a much stronger encryption and is more secure
• Provides authentication to ensure that only authorized users can log on to your WLAN
• It is much easier to configure
• It uses a standard algorithm on all compliant products to generate a key from a textual passphrase
Configuring WPA on the VT2542
1 Select the WPA option on the Wireless Security page.
2 Select the encryption type (WPA, WPA2, WPA/WPA2).
3 Enter the Group Key Interval.
4 Select the Radius Server if the authentication type is remote; if it is local, select Pre-Shared Key.
5 Enter the IP Address, Port, Secret (code), and PSK String.
6 Click Save.
