Chapter 3
Wireless Security Settings
Your wireless data transmissions can be received well beyond your walls by anyone with a
compatible adapter. For this reason, use the security features of your wireless equipment. The
RangeMax NEXT provides highly effective security features which are covered in detail in this
chapter. Deploy the security features appropriate to your needs.
Understanding WN802T Wireless Security Options
There are several ways you can enhance the security of your wireless network:
•
Restrict Access Based on MAC address.
You can restrict access to only trusted PCs so that
unknown PCs cannot wirelessly connect to the WN802T. MAC address filtering adds an
obstacle against unwanted access to your network, but the data broadcast over the wireless link
is fully exposed.
•
Turn Off the Broadcast of the Wireless Network Name (SSID).
If you disable broadcast of
the SSID, only devices that have the correct SSID can connect. This nullifies the wireless
network “discovery” feature of some products such as Windows XP, but the data is still fully
exposed to a determined snoop using specialized test equipment like wireless sniffers.
•
Use WEP.
Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most determined
eavesdropper.

Wireless Security Settings
v1.0, August 2007
•
Use WPA-PSK or WPA2-PSK.
Wi-Fi Protected Access (WPA) provides stronger data
encryption than WEP. The very strong authentication along with dynamic per frame rekeying
of WPA make it virtually impossible to compromise. The preshared key (PSK) is common to
all users. Because this is a recent standard, wireless device driver and software availability
may be limited.
•
Use WPA-PSK or WPA2-PSK with Radius.
Using a Remote Authentication Dial In User
Service (RADIUS) authentication server allows centralized authentication management with
individual user names and passwords.
WEP/WPA Settings
The WN802T Access Point is set by default “None” or no authentication. When setting up
Network Authentication, bear in mind the following:
Not all wireless adapters support WPA or WPA2. Windows XP and Windows 2000 with Service
Pack 3 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.
•
Network Authentication
. You can configure the RangeMax NEXT to use the types of
network authentication shown in the table below.
Table 3-1. Network Authentication Types
Type
Description
None
No data encryption
WEP
Wired Equivalent Privacy using either 64-bit or 128-bit data
encryption.
WPA-PSK (TKIP)
Wi-FI Protected Access with Pre-Shared Key, uses WPA-PSK
standard encryption with TKIP encryption type.
WPA2-PSK (AES)
Wi-FI Protected Access with Pre-Shared Key, uses WPA-PSK
standard encryption with AES encryption type. Only select this if all
clients support WPA2.
WPA-PSK (TKIP) + WPA2-PSK
(AES)
This selection allows clients to use either WPA-PSK (TKIP) or
WPA2-PSK (AES).
WPA with Radius
If selected, you must configure the Radius Server Settings Screen.
WPA2 with Radius
Only select this if all clients support WPA2. If selected, you must use
AES encryption, and configure the Radius Server Settings Screen.
WPA and WPA2 with Radius
If selected, encryption must be TKIP + AES. If selected, you must
configure the Radius Server Settings Screen.

Data Encryption
. The available options depend on the Network Authentication setting
selected (see
Table 3-1
above); otherwise, the default is None. The Data Encryption settings
are explained in the table below:
•
WEP Authentication Type.
WEP can be authenticated using Open System or Automatic. If
set to Open System, clients can only associate to the wireless access point by using the Open
System option. If set to Automatic, clients can associate to the wireless access point using both
Open System and Shared Key. Setting the Authentication Type to Automatic will detect which
WEP authentication method is being used. The default is Automatic.
•
Use of Passphrases and Keys are explained below:
–
Passphrase.
To use the Passphrase to generate the WEP keys, enter a passphrase and click
the Generate Keys button. You can also enter the keys directly. These keys must match the
other wireless stations.
–
Key 1, Key 2, Key 3, Key 4
. If using WEP, select the key to be used as the default key.
Data transmissions are always encrypted using the default key. The other keys can only be
used to decrypt received data.
–
WPA Preshared Key Passphrase.
If using WPA-PSK, WPA2-PSK or WPA-PSK +
WPA2-PSK, enter the passphrase here. All wireless stations must use the same passphrase
(network key). The network key must be from 8 to 63 characters in length.
Table 3-1. Data Encryption Settings
Data Encryption Type
Description
None
No encryption is used.
64 bits WEP
Standard WEP encryption, using 40/64 bit encryption.
128 bits WEP
Standard WEP encryption, using 104/128 bit encryption.
TKIP
Automatic encryption with WPA-PSK; requires passphrase
AES
Automatic encryption with WPA2-PSK; requires passphrase
