3.4 Establish secure connection with AP by WPS

Wi-Fi Protected Setup (WPS) is the latest wireless network technology which makes wireless network setup become very simple. If you have WPS-enabled wireless access point, and you want to establish a secure connection to it, you don’t have to configure the wireless access point and setup data encryption by yourself. All you have to do is to go to the WPS setup page of this wireless card, click a button, and then press a specific button or enter a set of 8-digit code on the wireless access point you wish to establish a secure connection - just three simple steps!

For older wireless access points, it’s possible to perform a firmware upgrade to become a WPS-enabled access point. Since they may not have a hardware button to press for WPS setup, you can use an alternative WPS setup method - input the pin code. Every WPS-compatible wireless network card support pin code configuration method; you can just input the code to wireless access point, and the wireless access point and wireless network card will do the rest for you.

This wireless network card is compatible with WPS. To use this function, the wireless access point you wish to connect to must support WPS function too. Now, please follow the following instructions to establish secure connection between WPS-enabled wireless access point and your wireless network card.

This wireless network card supports 2 kinds of WPS: PIN code and Push-Button.

Please follow the following instructions to setup WPS:

1. Right-click Client configuration utility icon, and click ‘ Open Config Utility ’.

26

2. Click ‘ Wi-Fi Protect Setup ’ menu.

3. You can use PIN code or Push-Button configuration, and WPS-compatible wireless access point must use the same type of WPS. For instructions on setup each type of WPS, see next 2 chapters for detailed instructions.

27

3.4.1 PIN Code

To use PIN Code, please click ‘ Pin Input Config (PIN) ’ button:

You’ll be prompted to select an access point you wish to connect. If you know its SSID, click ‘ Yes ’, otherwise click ‘ No ’.

If you select ‘ Yes ’, a list of all WPS-compatible AP nearby will be displayed; you can click ‘ Refresh ’ to rescan, then select an AP and click ‘ Select ’ button.

If you select ‘ No ’, wireless network card will prompt you to enter 8-digit PIN code into your AP, without selecting an AP in advance.

28

After you select ‘ Yes ’ or ‘ No ’ in previous step, network card will attempt to connect to

WPS-compatible AP, and an 8-digit number will appear. Please input this number to

AP’s configuration menu within 2 minutes, and network card will establish secure connection with AP automatically.

To stop this procedure before connection is established, click ‘ Cancel ’.

3.4.2 Push Button

To use Push-Button WPS configuration, please click ‘ Push Button Config (PBC) ’ button. This is the easiest way to establish secure connection by WPS, but if there’re more than one WPS-compatible AP using Push-Button config, please use PIN Code instead.

29

After you click “ Push Button Config(PBC) ”, a message box will appear:

Please activate Push-Button function on wireless access point now, and wireless network card will establish secure connection with access point within one minute.

CHAPTER 4 Soft-AP Function

Excepting become a wireless client of other wireless access points, this wireless adapter can act as a wireless service provider also! You can switch this wireless adapter’s operating mode to ‘AP’ mode to simulate the function of a real wireless access point by software, and all other computers and wireless devices can connect to your computer wirelessly, even share the internet connection you have!

Please follow the instructions in following chapters to use the AP function of your wireless card.
