Most Wireless support networks allow users to connect simply by providing the proper password. Some are completely unsecured and require no verification at all. Although uncommon, you may also come across secured wireless networks that require the presence of a verified signing certificate on your computer. This certificate must be properly installed on your machine before you are granted access to the network. Once you understand the required steps, installing a wireless certificate in Windows 7 support requires just a few clicks.(see also:How to setup a Home network in Windows 7)
