Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards. Location of the network device drivers in a simplified structure of the Linux kernel.
This is changing with the adoption of utilities such as NetworkManager and wicd that allow users to automatically switch between networks, without root access or command-line invocation of the traditional wireless tools.

For example, Ralink drivers report incorrect dBm readings and Realtek drivers do not include trailing 4-byte CRC values. [citation needed] For versions of Windows prior to Windows Vista, some packet analyzer applications such as Wildpackets' OmniPeek and TamoSoft's CommView for WiFi provide their own device drivers to support monitor mode.
Wireless icon. A wireless network is a computer network that uses wireless data connections between network nodes. [1] Wireless networking allows homes, telecommunications networks, and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.

Intel included Wi-Fi Direct on the Centrino 2 platform, in its My WiFi technology by 2008. [13] Wi-Fi Direct devices can connect to a notebook computer that plays the role of a software Access Point (AP). The notebook computer can then provide Internet access to the Wi-Fi Direct-enabled devices without a Wi-Fi AP.
