1 )  If you see the message Windows cannot configure this wireless connection, 
this is usually because Windows configuration utility is disabled or you are 
running another wireless configuration tool to connect the wireless network.

Configuration in the Services list on the right side.

If you can find other wireless network except your own, please follow the steps below:
•  Check the WAN LED indicator on your wireless router.
•  Make sure your computer/device is still in the range of your router/modem. Move 
closer if it is currently too far away.
If you can find your wireless network but fail to connect, please follow the steps below:
•  Authenticating problem/password mismatch:
1 )  Sometimes you will be asked to type in a PIN when you connect to the wireless 
network for the first time. This PIN is different from the Wireless Password/
Network Security Key. Usually you can only find it on the label of your router.
2 )  If you cannot find the PIN or entering the PIN still does not work, you may 
choose Connecting using a security key instead, and then type in the Wireless 
Password/Network Security Key.
3 )  If it continues to show the note Network Security Key Mismatch, it is suggested 
to confirm the wireless password of your wireless router.
  Note: Wireless Password/Network Security Key is case sensitive.
