WPA (WiFi Protected Access)
Not all wireless adapters support WPA. Furthermore, client software is required on the client.
Windows XP and Windows 2000 with Service Pack 3 or above do include the client software that
supports WPA. Nevertheless, the wireless adapter hardware and driver must also support WPA.
Consult the product document for your wireless adapter and WPA client software for instructions
on configuring WPA setting.
To configure WPA:
1.
From the Wireless Settings page, select the WPA Security Option and scroll to display the
WPA Radius settings shown below.
2.
Enter the WPA settings.
These settings are required for communication and authentication from a Radius server. A
Secondary Radius Server can be configured which is used if the Primary Radius Server fails.

Configuring Your Wireless Card Access List
By default, any wireless PC that is configured with the SSID and WEP/WPA settings has access to
your wireless network. For increased security, you can restrict access to the wireless network to
only allow specific PCs based on their MAC addresses.

careful about selecting the Turn Access Control On checkbox. If your
computer’s MAC address is not in the access control list, then you will lose
your wireless connection when you click Apply. You must then access the
wireless voice gateway from a wired computer, or from a wireless computer
that is on the access control list, to make any further changes.
