The original shipping version of Windows XP included rudimentary support which was dramatically improved in Service Pack 2. Support for WPA2 and some other security protocols require updates from Microsoft. Many hardware manufacturers include their software and require the user to disable Windows’ built-in Wi-Fi support.
Miracast support was built into stock Android as of version 4.2 (Android Jelly Bean) [38] [39] [40] - as of January 2013, the LG Nexus 4 and Sony's Xperia Z, ZL, T and V officially supported the function, [41] as did HTC One, Motorola in their Droid Maxx and Droid Ultra flagships, and Samsung in its Galaxy S III and Galaxy Note II under the ...
wpa_supplicant is a free software implementation of an IEEE 802.11i supplicant for Linux, FreeBSD, NetBSD, QNX, AROS, Microsoft Windows, Solaris, OS/2 (including ArcaOS and eComStation) [2] and Haiku. [3] In addition to being a WPA3 and WPA2 supplicant, it also implements WPA and older wireless LAN security protocols.
From March 13, 2006, to June 30, 2020, WPA2 certification was mandatory for all new devices to bear the Wi-Fi trademark. [11] In WPA2-protected WLANs, secure communication is established through a multi-step process. Initially, devices associate with the Access Point (AP) via an association request.
The soft AP provides a version of Wi-Fi Protected Setup with its push-button or PIN-based setup. When a device enters the range of the Wi-Fi Direct host, it can connect to it, and then gather setup information using a Protected Setup-style transfer. [9] Connection and setup is so simplified that it may replace Bluetooth in some situations. [11]
The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup (WPS), originally Wi-Fi Simple Config, is a network security standard to create a secure wireless home network.
hostapd (host access point daemon) is a user space daemon software enabling a network interface card to act as an access point and authentication server. There are three implementations: Jouni Malinen's hostapd, OpenBSD's hostapd and Devicescape's hostapd.
The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.
