Sending the frame from the access point to a station is called a "sanctioned technique to inform a rogue station that they have been disconnected from the network". [1] An attacker can send a deauthentication frame at any time to a wireless access point, with a spoofed address for the victim.
Many hardware manufacturers include their software and require the user to disable Windows’ built-in Wi-Fi support. Windows Vista, Windows 7, Windows 8, and Windows 10 have improved Wi-Fi support over Windows XP with a better interface and a suggestion to connect to a public Wi-Fi when no other connection is available.

False negatives occur when the wireless intrusion prevention system fails to detect an access point actually connected to the secure network as wired rogue. False negatives result in security holes. If an unauthorized access point is found connected to the secure network, it is the rogue access point of the first kind (also called as “wired ...
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
Using NAC in a mobile deployment, where workers connect over various wireless networks throughout the workday, involves challenges that are not present in a wired LAN environment. When a user is denied access because of a security concern, productive use of the device is lost, which can impact the ability to complete a job or serve a customer.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.
802.1X-2001 defines two logical port entities for an authenticated port—the "controlled port" and the "uncontrolled port". The controlled port is manipulated by the 802.1X PAE (Port Access Entity) to allow (in the authorized state) or prevent (in the unauthorized state) network traffic ingress and egress to/from the controlled port.
This Linksys WRT54GS, a combined router and Wi‑Fi access point, operates using the 802.11g standard in the 2.4 GHz ISM band using signalling rates up to 54 Mbit/s. IEEE 802.11 Wi-fi networks are the most widely used wireless networks in the world, connecting devices like laptops (left) to the internet through a wireless router (right).
