Chapter 5: Configuring the Wireless-N ADSL2+ Gateway
The Wireless Tab

Wireless-N ADSL2+ Gateway

The Wireless Security Tab

The Wireless Security settings configure the security of your wireless network. There are six wireless security 
options supported by the Gateway: WPA-Personal, WPA2-Personal, WPA-Enterprise, WPA2-Enterprise, RADIUS, 
and WEP. WPA stands for Pre-Shared Key, which is a security standard stronger than WEP (Wired Equivalent 
Privacy) encryption. WPA2 is a more advanced, more secure version of WPA. WPA-Enterprise, WPA2-Enterprise, 
and RADIUS use a RADIUS (Remote Authentication Dial-In User Service) server for authentication. These are 
briefly discussed here. For detailed instructions on configuring wireless security for the Gateway, turn to 
“Appendix B: Wireless Security.”

If you want to disable wireless security, select 

Disable

 from the drop-down menu for Security Mode.

Security Mode. Select the mode you want your network to use, 

WPA-Personal

WPA2-Personal

WPA-Enterprise

WPA2-Enterprise

RADIUS

,

 

or 

WEP

. If you have devices using WPA-Personal and WPA2-

Personal, select 

WPA2-Personal

.

WPA-Personal

Encryption. Select the method you want to use, 

TKIP

 or 

AES

. (AES is a stronger encryption method than TKIP.)

Pre-shared Key. Enter the key shared by the Gateway and your other network devices. It must have 
8 to 63 characters.

Key Renewal. Enter the Key Renewal period, which tells the Gateway how often it should change the dynamic 
encryption keys.

When you have finished making changes to this screen, click the 

Save Settings

 button to save the changes, or 

click the 

Cancel Changes

 button to undo your changes. Click

Figure 5-14: Wireless Security - WPA-Personal

IMPORTANT:

 If you are using wireless security, 

always remember that each device in your 
wireless network MUST use the same wireless 
security method and shared key, or else the 
network will not function correctly. If you have 
devices using WPA-Personal and WPA2-Personal, 
you should use WPA2-Personal.
