Then how do you find out the SSID? And how do you set the SSID? Let’s immediately look at the following explanation.

SSID explanation

SSID stands for service set identifier which is identified by a network ID. SSID is the identity of a network on a WiFi network device. SSID can make it easier for us in devices that want to connect to a WiFi network by searching for the network so we can access the internet.

SSID is a place that contains the name of the access point. In simple terms, SSID is a name that belongs to a WiFi network, which if you want to connect to the internet, you have to look for a name that matches the network you want.

If you just have a WiFi network and have made settings, the SSID and password are usually set by default by the system. It is recommended that you change the default SSID and password so that you can easily recognize your WiFi network device.

Usually the network has a different SSID depending on the user, because if you have the same SSID, then you will be confused in finding each network. The SSID character is a total of 32 characters and the SSID is a combination of letters, numbers and symbols.

SSID function

The SSID function is to identify a WiFi network so you can connect easily. If you currently want to use a WiFi network, then your device must select the network used.

If WiFi has a different SSID and is used to display identification that is sent over the WLAN network. This assigns the password of the device connected to the BSS.

If you have a wireless network, then you can give it a name as you wish so it’s easy to recognize it.

If there are devices trying to connect to your network then your devices usually have the same SSID. A device cannot be allowed to connect with the BSS unless the device has a specific SSID provided.

SSID type

The two types of SSID, namely hidden and public SSID, are explained below:

  • Hidden SSID

Hidden SSID is a type of hidden SSID. As the name suggests, this SSID is hidden on the network so that it cannot be accessed freely by other people. However the SSID is not completely undetectable as Windows 10 can still detect it.

To be able to connect to this hidden SSID, users must know the SSID and password. By knowing the hidden SSID, each user who wants to connect must enter a password according to the SSID that was created.


    Public SSID

In contrast to the hidden SSID, this public SSID allows the WiFi network to be used by anyone freely without entering a key or WEP key. To see the public SSID is very easy for devices that support wireless.
