Introducing SSID (Service Set Identifier)

An SSID, which stands for Service Set Identifier, is like a unique name tag for a Wi-Fi network.

People use SSIDs in both their homes and businesses for Wi-Fi networks.

You’ll usually come across them when you connect your gadgets, like smartphones or laptops, to a Wi-Fi or wireless network.

While many people come across and use the term SSID every day, there’s a considerable number who haven’t heard of it before.

Moreover, even among those who are familiar with the term, many may not fully grasp its meaning or purpose.

This article intends to offer a thorough explanation of what SSID represents, how it works, and why it’s important.

By exploring these details, readers will develop a clearer understanding of this frequently encountered but sometimes confusing concept.

What is a Service Set Identifier (SSID)?

SSID stands for Service Set Identifier, and it serves as the name for your Wi-Fi network or wireless network.

An SSID’s main job is to act like a special name tag for a particular Wi-Fi network. It’s what we commonly call the network name.

The SSID is super important because it helps devices connect to the right network, especially when there are many networks around in the same place.

When you click on the wireless signals on your phone or laptop, you will see different names for the wireless signals that you can connect to if you know the passwords.

You can also see the Wi-Fi network to which you are currently connected.

Typically, those names are Wi-Fi SSIDs. That Wi-Fi name is called SSID, which stands for Service Set Identifier, and it is configured on your access points.

These are the names that clients use to identify and join wireless networks. As seen in the picture above, it can be airport Wi-Fi or other examples. I’ve just shown you. These are some instances.

An SSID can be as long as 32 characters. Wireless routers and access points send out the SSID so that users can find and connect to a particular wireless network.

Sometimes, when you get a new router, it comes with a default SSID, which is a mix of the manufacturer’s name and some random numbers and letters.

To avoid confusion in places with lots of Wi-Fi networks, it’s a good idea to change this default SSID to something else.

How Does SSID Work?

The SSID operates through the broadcasting of a signal by the router or access point (AP) in the form of a “beacon.”

This beacon is a specific type of management frame utilized in wireless local-area networks (WLANs) based on the IEEE 802.11 standard.

The router sends out these beacons at regular intervals. Any device within the range of the beacon can detect and view the SSID.

When a computer or device intends to connect to a wireless network, it actively searches for the SSID.

Once the SSID is located, the computer will initiate a connection attempt to the network using the provided password or authentication credentials.

How to Find the SSID on Different Devices

Most routers have the SSID name written somewhere on the router itself, usually on the bottom, back, or side. In that same area, you might also find the Wi-Fi network password or WPA key.

Once people understand what an SSID is, it becomes really important for them to find and use the right Wi-Fi networks when they need them.

Now, if it’s a new network or one that hasn’t changed names, the default SSID is usually printed on a sticker stuck to the router. Most routers have the SSID name written somewhere on the router itself, usually on the bottom, back, or side. You’ll often find this sticker on the router’s bottom corner.

In that same area, you might also find the Wi-Fi network password or WPA key.

But lots of people prefer to give their network a unique name they can easily recognize instead of using the default one.

Alternatively, you can locate it on your different devices. To find the SSID on any device you are using, follow this step:

If you’re using a Windows device, click on the Wi-Fi icon on the desktop taskbar. This will show a list of local networks, each labeled with its SSID.

For Android devices, go to the Settings app, select “Wi-Fi,” and you’ll see a list of local SSIDs available for connection.

On iOS devices, open the Settings app, tap on “Wi-Fi,” and you’ll find a list of nearby networks, each with its own SSID.

For macOS users, choose the Wi-Fi icon on the menu bar to see a list of available local SSIDs.

How to Change Your SSID

Changing your SSID is a recommended practice to prevent confusion.

In situations where you and your neighbor use the same router model, there is a high likelihood of having similar SSIDs.

Although there might be slight variations in the last few characters, the overall similarity can lead to confusion, especially when guests attempt to connect to your Wi-Fi network.

Therefore, changing your SSID helps to differentiate your network and avoid any potential confusion or connectivity issues.

Changing your SSID is a straightforward process. Here are the steps to follow:

Connect to your router using a computer or smartphone.
Locate your router’s IP address. Learn how to find your IP address here and proceed to the next steps.
Open a web browser on your device.
Enter your router’s IP address in the browser’s address bar.
Log in to the router’s administrative interface using your admin credentials. If you’re unaware of your username and password, you can try checking the back or underside of the router for this information.
Navigate to the wireless local area network (WLAN) settings of your router.
Look for the field labeled “SSID” and enter your desired Wi-Fi name or network name.
Save the changes and exit the router’s settings interface.

By following these steps, you can easily change your SSID to a desired Wi-Fi name.

Note

It’s important to note that the process of changing an SSID name or password can vary slightly depending on the specific Wi-Fi network and router you are using.

Therefore, the exact steps involved may differ from one setup to another.

It is advisable to consult the user manual or visit the manufacturer’s website for your specific router model.

This will provide accurate instructions on how to effectively modify the SSID name or password.

Moreover, after changing your SSID, it may take a short period, typically a few seconds to a minute, for your devices to display the updated SSID in their lists of available Wi-Fi networks.

It’s also important to note that even after the new SSID appears, it’s possible to see both the old and new SSIDs listed.

In such cases, it is recommended to wait for a few minutes and periodically refresh the list of networks on your devices.

This allows the devices to fully update and display only the new SSID, ensuring clarity and accurate identification of the desired network.

How to Name Your SSID

When it comes to choosing a good name for your SSID, many people prefer to customize it as soon as they set up their router.

Especially in crowded areas, having a unique and personal SSID makes it simpler to find your Wi-Fi network among others with generic names.

While it might be tempting to use creative and funny Wi-Fi names, it’s crucial to be cautious to ensure the name remains appropriate for all visitors who might need to connect to your internet.

Avoid overly explicit or inappropriate names that could potentially offend or make people uncomfortable.

The best Wi-Fi network names are short, easily recognizable, and stand out in a sea of random letters and numbers.

However, refrain from using any personal information in the name.

While funny Wi-Fi names can be entertaining, be aware that you might attract attention, and others could make fun of your unique SSID name if it’s too obvious.

Final Note

The SSID serves as the identifier for your Wi-Fi router and is broadcast to nearby devices.

Its purpose is to help users select the correct network to connect to, particularly when multiple networks are available in the vicinity.

While they are intended to be unique, default SSIDs from routers of the same brand and model often share similarities or are identical.

This means that if a neighbor has the same router model as you, there is a possibility of having the same SSIDs.

To avoid confusion and potential connectivity issues, it is advisable to change your SSID during the router setup process.

Regarding hiding your SSID, it has its pros and cons. On one hand, hiding your SSID can prevent unauthorized individuals from seeing your Wi-Fi network on their list of available networks, offering a certain level of security.

On the other hand, it can make it more difficult for legitimate devices, including yours and other household members’, to reconnect to your network.

It’s important to note that the security of your Wi-Fi network is not determined by the SSID itself.

Instead, you should focus on securing your Wi-Fi network by implementing strong Wi-Fi passwords, utilizing robust encryption protocols like WPA2 or WPA3, and enabling your router’s firewall.

These measures collectively contribute to enhancing the security of your network and protecting it from potential threats.

By understanding the role of SSID and implementing appropriate security measures, you can maximize its functionality and safeguard your Wi-Fi network effectively.

Stay vigilant and enjoy a secure and reliable wireless connection.
