Network and Sharing Center

Network and Sharing Center in Windows 7 allows you to determine which networks your computer is connected to and the network designation assigned to those networks. The first time that you connect to a network you must choose a network location.

When you connect to a new network, Windows prompts a dialog box asking you whether the network is a Home, a Domain or a Public network. Additionally, Windows 7 remembers the designation that you assign to the network and associates it with the properties of the network so that every time you connect to that network, the same designation will be applied.

Home and Small Office Network Setups

A small wired network may consist of an 8 or 5 port network switch which connects all computers together, and one Windows 7 machine running ICS bridging the network and the Internet connection through the ISP cable or dial-up modem as shown below. Internal computers can obtain their IPv4 configuration from the ICS machine while the ICS machine get its configuration from the modem which in turn is configured by the ISP. Some ISPs may provide you with a combined modem and router where you may omit the ICS computer as this role will be provided by the modem/router device.

Wireless Network Security

We may be reluctant to modify a working configuration or so much time may have been dedicated in troubleshooting and configuring a practical solution that we tend to ignore the security part of the wireless setup!
