A common method is to direct all World Wide Web traffic to a web server, which returns an HTTP redirect to a captive portal. [8] When a modern, Internet-enabled device first connects to a network, it sends out an HTTP request to a detection URL predefined by its vendor and expects an HTTP status code 200 OK or 204 No Content.
The glass–liquid transition, or glass transition, is the gradual and reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle "glassy" state into a viscous or rubbery state as the temperature is increased. [2]
As a standalone device, the AP may have a wired or wireless connection to a router or router, but, in a wireless router, it can also be an integral component of the networking devices itself. An WAP & AP is differentiated from a hotspot , which can be a physical location or digital location where Wi-Fi or WAP access is available.
Some devices (such as wireless routers) will have unique default router usernames and passwords printed on a sticker, which is more secure than a common default password. Some vendors will however derive the password from the device's MAC address using a known algorithm, in which case the password can also be easily reproduced by attackers.
Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance interoperability certification, based on the IEEE 802.11e standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks. WMM prioritizes traffic according to four Access Categories (AC): voice (AC_VO), video (AC_VI), best ...
In computer networking, the ICMP Internet Router Discovery Protocol (IRDP), also called the Internet Router Discovery Protocol, is a protocol for computer hosts to discover the presence and location of routers on their IPv4 local area network. Router discovery is useful for accessing computer systems on other nonlocal area networks.
A wireless LAN controller (WLC) is a network device used to monitor and manage wireless access points in an organization. WLCs are connected to routers and allow devices from across the organization to connect to the router via access points.
Bluetooth high speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols. Bluetooth Low Energy , previously known as Wibree, [ 95 ] is a subset of Bluetooth v4.0 with an entirely new protocol stack for rapid build-up of simple links.
