A Wireless to LAN proxy enables network devices and computers on a private network to access the Internet through a cabled network connection. Microsoft Windows 7 Professional and Ultimate include a feature called Internet Connect Sharing, or ICS, that provides IP addressing and Internet proxy service to devices and computers on a private network. Windows 7 Professional and Ultimate also feature the ability to create ad hoc wireless networks such that the wireless network adaptor on the Windows 7 computer acts like a wireless access point to which wireless devices can associate in order to connect to a network. Enable ICS and ad hoc wireless networking on Windows 7 Professional or Ultimate in order to create a wireless to LAN proxy.
