Though we usually use networks for personal or business use, few people know what is an SSID for WiFi. It is an important term for your network. You might meet it every day, but never know what it is.
Here we will explain the definition of SSIDs and everything you should know about them. In addition, we provide solutions to protect your cyber security.
What Is An SSID?
SSID stands for Service Set Identifier. Wireless routers and access points broadcast SSIDs, making users easily locate the wireless network.
In short, it is the Wi-Fi name. When you try to connect to the WiFi and open the device settings, the names appear in the available network lists. For example, if you connect to the WiFi in a bookstore, its SSID might be “Bookstore Wi-Fi.”
Technically, it is a unique identifier consisting of random numbers or letters. An SSID can be 32 characters in length. With it, you can quickly locate the network you want to connect. To secure your own security and privacy, you can change your default SSID and Wi-Fi password.
Is the SSID the Same as the IP Address?
The answer is no. An IP address is a string of numbers that are assigned to the connected device, making sure your data transforms back and forth to the right address.
On the other hand, SSID refers to the WiFi name, it identifies the network users want to use.
What If Two Networks Have the Same SSIDs?
When you try to connect to a private network in an apartment, you might find several same SSIDs. Due to the same router brand and default SSID numbers, you can’t easily locate the one you want to connect.
Besides, you might be refused for the wrong password. It is not only confusing yourself but also confusing your device. If two networks use the same SSIDs, your device might choose the one with the stronger signal.
