ssid Wi-Fi networks support a type of network name called SSID (Service Set IDentifier). Wi-Fi access points and clients are each assigned a SSID to help identify one another. When we speak of wireless network names, we typically are referring to SSIDs. Wireless broadband routers and wireless access points establish a wireless network using a SSID. These devices are configured with a pre-defined default SSID (network name) by the manufacturer at the factory. Users are encouraged to change the default name.
