Configuring Your Wireless Settings
First configure your wireless network connection, then configure your Wireless Access Point
settings. Lastly, configure your Wireless Security Type that matches your network configuration.
To configure your wireless network and enable your wireless access point:
1.
Select Network Configuration from the main menu and Wireless Settings from the submenu.
The Wireless Settings screen will display (as shown in
Figure 3-3
).
2.
Enter your Wireless Network Name (SSID). The default SSID is NETGEAR, but NETGEAR
strongly recommends that you change your Network Name to a different value. It can be up to
32 alphanumeric characters and is case sensitive.
3.
Select the correct Country/Region setting to comply with local regulatory requirements
(
“Understanding Wireless Settings” on page 3-3
for an explanation of these settings).
4.
Select the appropriate Operating Mode for your area and antenna configuration—802.11b/g, b
only, or g only.
5.
The
Enable Allow Broadcast Name (SSID)
radio box is checked (enabled) by default. When
enabled, the SSID will broadcast its name to all Wireless Stations. Stations which have no
SSID (or a “null” value) can then adopt the correct SSID for connections to this Access Point.
6.
Check the
Enable Wireless Access Point
radio button to turn on the wireless radio.
To configure the Wireless security settings on your ProSafe DGFV338:

1.
Select the Wireless Security Type option you wish to use for your Wireless Network. The
options are described in
“Wireless LANs” on page 3-4
.
•
None
: No data encryption is used.
•
WEP
. This enables WEP and requires at least one shared key (see
“Configuring WEP” on
page 3-10
).
•
WPA-PSK.
Uses standard WPA-PSK encryption (see
“Configuring WPA-PSK” on
page 3-12
).
•
WPA2-PSK
. WPA2 is a later version that uses only AES encryption (see
“Configuring
WPA2-PSK” on page 3-13
.)
•
WPA-PSK and WPA2-PSK
. Allows clients to use either WPA (with TKIP encryption) or
WPA2 (with AES encryption) (see
“Configuring WPA-PSK and WPA2-PSK” on
page 3-14
.)
•
WPA with RADIUS
.
This version of WPA requires the use of a RADIUS server for
authentication.(see
“Configuring WPA-PSK” on page 3-12
.).
•
WPA2 with RADIUS.
This is later version of WPA and requires the use of a RADIUS
server (see
“Configuring WPA2 with RADIUS” on page 3-16
.)
•
WPA and WPA2 with RADIUS
. This version of WPA and WPA2 allows the use of either
AES or TKIP encryption with the RADIUS server (see
“Configuring WPA and WPA2
with RADIUS” on page 3-17
.).

2.
In the Wireless Security Type section, select the WEP radio box.
3.
From the WEP section, define the WEP security characteristics:
•
Select Authentication type from the drop-down menu:
–
Automatic (default). Allows either Open System or Shared Key
–

•
Select which encryption strength you want to use from the Encryption drop-down menu
(64 bits, 128 bits, or 152 bits).
•
Enter a WEP Passphrase (a word or group of printable characters) in the Passphrase box
and click Generate Keys to automatically configure the WEP Key(s).
You can manually or automatically program the four data encryption keys. These values
must be identical on all PCs and devices in your network. Choose either:
–
Automatic – Click
Generate
. The four key boxes will be automatically populated
with key values.
–
Manual – Enter the number of hexadecimal digits appropriate to the encryption
strength: 10 digits for 64-bit and 26 digits for 128-bit (any combination of 0-9, a-f, or
A-F).
•
Select the key to be used as the default key by checking the radio box. (Data transmissions
are always encrypted using the default key.)
See the document “Wireless Communications” for a full explanation of each of these
options, as defined by the IEEE 802.11 wireless communication standard. A link to this
document on the NETGEAR website is in
Appendix B, “Related Documents
.”

Note:
64-bit and 128-bit are the standard encryption strength options. 152-bit key
length is a proprietary mode that will only work with other wireless devices
that support this mode.

Configuring WPA-PSK
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 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 settings.
To configure WPA-PSK:
1.
From the
Wireless Security Type
section, select
WPA
.
WPA with PSK
will be selected by
default.
2.
Select the Data Encryption mode: AES or TKIP (TKIP is the default).
3.
Enter the Passphrase (Network Key). The 256-bit key used for encryption is generated from
the Passphrase.
4.
Enter the Key Lifetime (in minutes). This determines how often the encryption key is changed.
(Shorter periods give better security, but adversely affect performance.)
5.
Click
Apply
to save your settings.
Note:
If you use a wireless computer to configure WEP settings, you will be
disconnected when you click Apply. Reconfigure your wireless adapter to
match the new settings or access the wireless firewall from a wired computer
to make any further changes.

Configuring WPA2-PSK
Not all wireless adapters support WPA2. Furthermore, client software is required on the client.
Make sure your client card supports WPA2. Consult the product document for your wireless
adapter and WPA2 client software for instructions on configuring WPA2 settings.
To configure WPA2-PSK:
1.
From the
Wireless Security Type
section, select the
WPA2
radio button. By default
WPN
with PSK
will be selected and
Encryption
will be set to
AES
.
2.
Enter the preshared Passphrase (Network Key).The 256-bit key used for encryption is
generated from the Passphrase.
3.
Enter the Key Lifetime (in minutes). This determines how often the encryption key is changed.
(Shorter periods give better security, but adversely affect performance.)
4.
