Raspberry Pi Model A WiFi connection OK!

I googled a few more tutorials on using wireless adapter but still could not follow the instructions to connect to the internet.

One such tutorial mentions that Raspbian has a app for wifi connection.  So I startxed to run the app called WIFI config.  But I still could not connect under WPA PSK.  Then I found the app has WPS beside WPA. So I used the WPS menu to generate a PIN.  Then I went back to Win 7 to log on to the router and register the client with the PIN.  Then I went back to RPi to connect to the SSID of my wireless network.  Then I was happy to find the network connected.
