A wireless adapter, sometimes called a wireless network card or Wi-Fi card, is a device that allows a computer to connect to wireless Internet signals. Wireless adapters are common in laptop computers, but some desktops also have wireless adapter cards. If your computer cannot access any wireless networks, your wireless adapter may be disabled. Enabling a disabled adapter is a simple process, though you may need to wait some time before the adapter starts picking up wireless signals again.
