ProSafe Wireless-N 8-Port Gigabit VPN Firewall FVS318N
To set up a wireless profile, specify a name for the profile and the SSID, type of security with
authentication and data encryption, and whether or not the SSID is broadcast.
•Network authentication
The wireless VPN firewall is set by default as an open system with no authentication.
When you configure network authentication, bear in mind that older wireless adapters
might not support WPA or WPA2. Windows XP, Windows 2000 with Service Pack 3,
Windows Vista, and Windows 7 do include the client software that supports WPA.
However, client software is required on the client. Consult the product documentation for
your wireless adapter and WPA or WPA2 client software for instructions on configuring
WPA2 settings.
For information about the types of network authentication that the wireless VPN firewall
supports, see Configure and Enable Wireless Profiles on page 112.
•Data encryption
Select the data encryption that you want to use. The available options depend on the
network authentication setting described earlier (otherwise, the default is None). The data
encryption settings are explained in Configure and Enable Wireless Profiles on page 112.
Some concepts and guidelines regarding the SSID are:
•A basic service set (BSS) is a group of wireless devices and a single wireless access
point, all using the same wireless profile or service set identifier (BSSID). The actual
identifier in the BSSID is the MAC address of the wireless radio. (A wireless radio can
have multiple MAC addresses, one for each wireless profile.)
•An extended service set (ESS) is a group of wireless devices, all using the same identifier
(ESSID).
•Different devices within an ESS can use different channels. To reduce interference,
adjacent devices should use different channels.
•Roaming is the ability of wireless devices to connect wirelessly when they physically
move from one BSS to another one within the same ESS. The wireless device
automatically changes to the wireless access point with the least interference or best
performance.
Before You Change the SSID, WEP, and WPA Settings
For a new wireless network, print or copy the following form and fill in the settings. For an
existing wireless network, the network administrator can provide this information. Be sure to
set the Country/Region correctly as the first step.
