What is an SSID in Wi-Fi?
An SSID, or Service Set Identifier, is a unique name that identifies a wireless network. It distinguishes one Wi-Fi network from another, allowing devices to locate and connect to the correct network. The SSID can consist of up to 32 characters and can include letters, numbers, and special characters, although some characters may interfere with certain router settings.
When you turn on Wi-Fi on your iPhone, the device scans for available networks and displays a list that includes the SSIDs of all nearby networks. This naming convention helps users easily identify and choose the right network to connect to, particularly in areas where multiple networks may be available, like homes, offices, and public spaces.
How do I find the SSID of my Wi-Fi network on my iPhone?
To find the SSID of the Wi-Fi network you are connected to on your iPhone, go to the “Settings” app, then tap on “Wi-Fi.” At the top of the Wi-Fi settings, you will see a checkmark next to the network you are currently connected to.
