To find the SSID of a wireless network, locate the wireless router, and look for the SSID label on the bottom or side panel. Alternatively, open an Internet browser, type the router's IP address into the address bar, and press the Enter key. Enter the administrative username and password for your router, click the Login button and look for the SSID field in the router management system.
The SSID, or service set identifier, is the name of your Wi-Fi network; it is required to connect a device to the network. If you cannot access the router or the router management screen, open the Wi-Fi connection screen on your phone, tablet or computer, and choose the correct SSID from the available networks.
If you are in a location with a large number of wireless networks, or if you cannot pick the correct SSID from the list, find a device that is connected to your network. Open the wireless connection screen to see the SSID.
When you cannot remember your router login information and you do not have a connected device, you must reset the router to its factory settings. The specific process varies by router, but usually involves holding down the reset button for a set amount of time; check your manual for specific instructions.
