The Compaq Evo Model N600c ships running the Windows 7 operating system. If you want to connect your computer to a wireless network, you will first have to enable the unit's wireless networking capabilities.

Click "Control Panel."
Click "Network and Sharing Center."
Click "Change Adapter Settings."
Right-click on your Compaq Evo N600c's wireless networking icon and click "Enable." The ability to connect to wireless networks will now be turned on for your computer.
