WPS Operation Method
- Push Button: WPS capability requires the pressing of buttons located on the rear of the router and client devices. Some routers and devices have virtualized features that require activation through software on the individual devices. The device connects automatically without a password once the buttons are enabled.
- PIN: The access point or client device must be entered with the PIN found on the sticker that is adhered to the access point. Certain routers provide an instant PIN as soon as the device is connected, which can be used to enter the network. Devices that do not support WPS but do support the protocol use the immediate PIN feature.
- Network Feild Communication: To allow Near Field Communication (NFC) between a client device and an access point, the client device must be brought very close to the access point. The gadget is linked to the network and authenticated using a near field communicator. Support is offered on an optional basis. This is an out-of-band technique where the channel transfers data directly without utilising WPS.
- USB: Data is sent between the new device that has to be connected and the access point using a USB flash drive. Although this mode is deprecated, optional support is still offered.
Wifi Protected Setup (WPS)
The Wifi protected setup (WPS) is a wireless network security standard that tries to make connections between a router and wireless devices in a faster and easier way. WPS works only for wireless networks that use a password that is protected with the Wifi Protected Access Personal (WPA) or Wifi Protected Access2 (WPA2) Personal security protocols. WPS does not work on wireless networks that use the disfavoured Wired Equivalent Privacy (WEP) security, which can be cracked easily by any hacker with basic skills.
An optional certification program based on a technology called Wi-Fi Protected SetupTM makes it easier to set up security-enabled Wi-Fi® networks in homes and small offices. Wi-Fi Protected Setup allows network configuration and security activation using well-known procedures (such as pressing a button or entering a PIN) that are accessible to most users.
In a standard setup, you can’t connect a wireless device to a wireless network until you know the network name (also named Service Set Identifier(SSID)) and its password (also called WPA-PSK key). If you want to connect a device, like your smartphone or a laptop, to your wireless network then on your device, you must first pick the network that you want to connect to and then enter its security password.
