Chapter 5: Configuring the Dual-Band Wireless A+G Broadband Router

Dual-Band Wireless A+G Broadband Router
The Wireless Tab - Wireless Security
The Wireless Security settings configure the security of your wireless network. There are three wireless security
mode options supported by the Router: Pre-Shared Key, Pre-Shared Key + RADIUS, and WEP. (WEP stands for
Wired Equivalent Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These three are
briefly discussed here. For detailed instructions on configuring wireless security for the Router, turn to
“Appendix B: Wireless Security.”
Wireless Security
The security options are the same for your Wireless-A and Wireless-G networks. You can use different wireless
security methods for your networks; however, within each network (Wireless-A or Wireless-G), all devices must
use the same security method and settings.
Wireless-A Settings
Pre-Shared Key. This method offers two encryption methods, TKIP and AES, with dynamic encryption keys.
Select the type of encryption method you want to use, TKIP or AES. Enter the Passphrase, which can have 8 to 63
characters. Then enter the Key Renewal period, which instructs the Router how often it should change the
encryption keys.
Pre-Shared Key + RADIUS. This option features a Pre-Shared Key used in coordination with a RADIUS server
that uses either EAP-TLS or PEAP as its authentication method. (This should only be used when a RADIUS server
is connected to the Router.) First, select the type of encryption method you want to use, TKIP or AES. Enter the
RADIUS server’s IP address and port number, along with the authentication key shared by the Router and the
server. Last, enter the Key Renewal period, which instructs the Router how often it should change the encryption
keys.

radius: a protocol that uses an authentication
server to control network access.
IMPORTANT: If you are using the Pre-Shared Key
or Pre-Shared Key + RADIUS method, always
remember that each device in your wireless
network MUST use the same method and settings,
or else the network will not function properly.
