In addition, you can create a new connection manually referring to the following steps.
Click Start Menu -> Control Panel -> Network and Internet -> Network and Sharing Center->Set up a new connection or network->Manually connect to a wireless network
Now, Complete the Details of the Wireless Network, please type the name of the wireless network you want to connect to, which is the equivalent of the Network ID (SSID) field from your router's wireless configuration menus, and select the appropriate type of encryption.
If you are in a public environment, then it is a good idea to check the Hide characters box. Also, don't forget to check the other two boxes: 'Start this connection automatically' and 'Connect even if the network is not broadcasting'. These two allow you to connect automatically to the hidden wireless network. Once all data is completed, click on Next. When finish, you will see a message which says that you have successfully added the wireless network to your computer. If you are unsure on any of the settings, you can click on 'Change connection settings' and review them all.
I think this will help you.
