The Dynamic Host Configuration Protocol (DHCP) allows you to use Windows 7 to automatically configure the network properties for most devices on your home network. You’ll also need to configure a DHCP server (built-in on most routers) on your home network.


Open the Windows Control Panel, and then click Network and Internet.

The Network and Internet window appears.


Click Network and Sharing Center.

The Network and Sharing Center window appears.


In the left pane, click Change Adapter Settings.

The Network Connections window appears.


Double-click the network adapter you would like to configure (Wireless Network Connection in this example).

The Wireless Network Connection Status dialog box appears.


Under Activity, click the Properties button.

The Wireless Network Connection Properties dialog box appears.


Select Internet Protocol Version 4 (TCP/IPv4) and click the Properties button.

The dialog box pertaining to the selected connection appears.


Select Obtain an IP Address Automatically and Obtain DNS Server Address Automatically; then click OK and close the other network properties windows.

Your computer is now configured to use DHCP and will be automatically (and seamlessly) configured with the correct IP address, subnet mask, default gateway, and DNS server addresses, each time you turn your computer on.
