WPA (with RADIUS Server)

WPA (Wi-Fi Protected Access) provides dynamic key changes and

constitutes the best security solution. This function requires that a

RADIUS server is running on the network.

Figure 49

WPA (with RADIUS Server) Screen

1

Select WPA with RADIUS server from the

Security Mode

drop-down

menu.

2

Select WPA mode from the drop-down menu, three modes are

supported: WPA, WPA2, and Mixed mode.

3

Select Encryption technique from the drop-down menu, four options are

available: TKIP, AES, Auto for WPA AES for WPA2, and AES for both WPA

and WPA2.

WPA supports TKIP and AES Encryption technique, for some old module

of wireless client cards, they may only support TKIP. In this case, we

suggest you to select “AUTO for WPA, AES for WPA2”. If your wireless

client cards can support AES over WPA, we suggest you directly select

“AES for both WPA and WPA2”.

4

Enter the IP address of the RADIUS server on your network into the

RADIUS Server

field.

5

Enter the port number that the RADIUS server is operating on in the

RADIUS Port

field.

6

Enter the key for the RADIUS server in the

RADIUS Key

field.

By default, the WPA keys are changed every hour, but if you want to

change this setting, you can do so by specifying the required time in the

Re-key Interval

field.

WPS

Wi-Fi Protected Setup (WPS) integrates the new WLAN clients into your

wireless network easily. You can enable this function by entering the PIN

code via the web UI page or by pressing the WPS button on the rear side

of the device.

Figure 50

WPS Screen

Two methods to setup the WPS, you can choose either one of the

following method. Note that if you choose to use the PBC mode, then it

would be no need to enter the PIN code of the wireless NIC on this

screen.

■

1

Check the

Enable WPS Function

box. The WPS-PIN field will appear.

2

Enter the PIN code in the

WPS-PIN

field. And then click

Apply.

Please note that the PIN code is generated this way: on the client side,

run the WPS utility which is provided by the vendor of your Wi-Fi card

and select the PIN method. You should get an 8-digit PIN number from

the WPS utility.

Enter that 8-digit PIN number on this screen and click

Apply

to activate

this PIN method. Then the Router starts to negotiate the security with the

WLAN clients and WPS LED will start flashing. After the connection has

been established successfully, the WPS LED will then be off.

1

Press the WPS button located on the rear of the Router. Note that this

setup process will only be active for 2 minutes. Follow the instruction of

your WLAN NIC to set up the WPS.

The WPS LED shows the status of the WPS function. It has a number of

modes to help monitor the status of clients connecting to the Router

using the WPS protocol. The status is shown by three different flashing

rates: slow, medium and quick and when light constantly.

When the WPS button is pressed, or WPS is initiated using the PIN

method in the web interface, the WPS LED will flash at a medium rate for

up to 2 minutes to indicate that a WPS connection can be made. When a

connection attempt is underway, the LED will flash slowly.

If the connection has been successful, the WPS LED will remain

illuminated for 5 minutes. If the connection attempt has failed, the WPS

LED will flash rapidly for 5 minutes. You can re-try the connection by

pressing the WPS button, when the connection process will re-start.

If you want to add a further client to the Router, you do not need to wait

for the 5 minute period to end. You can press the WPS button (or use the

PIN method via the web interface) as soon as the first client is successfully

connected.

Note: The WPS function will be enabled for 2 minutes once WPS is

enabled either by pressing the button or by starting the PIN mode via the

web interface. This time will end before 2 minutes if a client has

successfully connected. Only one client should be connected to the

Router using WPS at any one time. Attempting to connect two or more

clients at once may result in connection failures.
