In IEEE 802.11 wireless local area networking standards (including Wi‑Fi), a service set is a group of wireless network devices which share a service set identifier (SSID)—typically the natural language label that users see as a network name. (For example, all of the devices that together form and use a Wi‑Fi network called "Foo" are a ...
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 ...
PRIVATE WiFi will automatically activate and connect to an encrypted server whenever you access the internet. If you change this default setting, you can activate PRIVATE WiFi at any time clicking on the status icon ( PC: right-click the icon in the Taskbar at the bottom right of your screen, Mac: click the Menu Bar icon at the top right of ...
A typical Wi-Fi home network includes laptops, tablets and phones, devices like modern printers, music devices, and televisions. Most Wi-Fi networks are set up in infrastructure mode, where the access point acts as a central hub to which Wi-Fi capable devices are connected. All communication between devices goes through the access point.
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.
When users chooses to hide the network name from the router's setup page, it will only set the SSID in the beacon frame to null, but there are four other ways that the SSID is transmitted. In fact, hiding broadcast of the SSID on the router may cause the Network interface controller (NIC) to constantly disclose the SSID, even when out of range. [2]
Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.
The Wi-Fi Alliance standardized these methods as Wi-Fi Protected Setup; however, the PIN feature as widely implemented introduced a major new security flaw. The flaw allows a remote attacker to recover the WPS PIN and, with it, the router's WPA/WPA2 password in a few hours. [ 45 ]
