The recommended way to set up your wireless network is to use a wireless access point (wireless router). A network set up this way is called an infrastructure network. If you have an infrastructure network in your home, you should configure your printer for use on that network.
If you don't have a wireless access point (wireless router) or would like to set up a standalone network between your printer and a computer with a wireless network adapter, you can set up an ad hoc network.
Click 
Control Panel Network and Internet.
Under Network and Sharing Center, click Connect to a Network.
In the Connect to a Network dialog, click Set up a wireless ad-hoc (computer-to-computer) network, and then click Next.
Follow the instructions in the “Set up a wireless ad hoc network” wizard. As part of the setup:
Create a network name or SSID for the network between the computer and your printer.
Write the name of your network in the space provided. Be sure to use the exact spelling and capitalization.

Go to the Security Type drop-down list, choose WEP, and then create a security key (or password).
WEP keys must be:
Exactly 10 or 26 hexadecimal characters. Hexadecimal characters are A–F, a–f, and 0–9.
Exactly 5 or 13 ASCII characters. ASCII characters are letters, numbers, punctuations, and symbols found on a keyboard
Write the password for your network in the space provided. Be sure to use the exact spelling and capitalization.

Windows Vista will enable the ad hoc network for you. It will appear in the “Connect to a network” dialog under “Available networks,” indicating that the computer is configured for the ad hoc network.
Close the Control Panel and any remaining windows.
Insert the printer software installation CD for Windows into the computer and follow the directions for wireless installation.
When the available networks are displayed, provide the network name and the security information you created in step 4. The installer will configure the printer for use with your computer.
