WPA-PSK or WPA2-PSK Wireless Security

When you are setting up wireless security, these guidelines will help make the process simpler and

easier:

•

Use an Ethernet cable to connect your computer to the router when you are setting up or

changing wireless settings. If you are connected wirelessly and you set up the wireless

security, you will lose your wireless connection when you apply the change.

•

Remember to note what your wireless settings are. For help keeping track of them, see

“Information to Gather Before Changing the Wireless Settings” on page 2-3

.

Wireless Adapter Compatibility

If you want to use WPA or WPA2, first make sure that the computers or devices that will connect

to your router are able to use this type of wireless security. Each computer or device will need:

•

A configuration utility that supports WPA or WPA2 for the wireless adapter.

•

Client software that supports WPA or WPA2. Windows XP Service Pack 2 and Windows XP

Service Pack 1 with the WPA patch do include the client software that supports WPA.

•

The wireless adapter hardware and driver must also support WPA or WPA2.

Note:

Before setting up wireless security, verify that your wireless connections are set up

and working. See

“Setting Up Your Wireless Connections” on page 2-2

.

Note:

For instructions for configuring wireless computers or personal digital assistants

(PDAs) for WPA-PSK, see the documentation for the product you are using.

Advanced Wireless Settings

Log in to the WGT624 v4 wireless router at its default LAN address of

http://

192.168.1.1

with its

default user name of

admin

and default password of

password

, or using whatever LAN address

and password you have set up.

To go to advanced wireless settings, click the Wireless Settings link in the Advanced section of the

main menu. The Advanced Wireless Settings page appears:

•

Enable Wireless Router Radio.

If you disable the wireless router radio, wireless devices

cannot connect to the WGT624 v4.

•

Enable SSID Broadcast.

If you disable broadcast of the SSID, only devices that have the

correct SSID can connect. Disabling SSID broadcast nullifies the wireless network ‘discovery’

feature of some products such as Windows XP.

•

Enable WMM.

Wi-Fi Multimedia (WMM) is a Quality of Service (QoS) feature that

prioritizes wireless data packets based on four access categories: voice, video, best effort, and

background. Applications without WMM and applications that do not require QoS, are

assigned to the best-effort category, which receives a lower priority than voice and video.

To receive the benefits of WMM QoS:

–

The application must support WMM.

–

You must enable WMM in your WGT624 v4 wireless router.

–

You must enable WMM in the wireless adapter in your computer.
