How to find the network security key on the router - PureVPN Blog

The Network Security Key, also known as the Wireless (WiFi) Network Password, is the password you use to connect your devices to a wireless network. Most routers have a default network security key that you can change through the device’s settings page.

Keeping your network security key is crucial as it helps protect your network from hackers. However, if you’ve lost your network key, don’t worry; we’ve covered you!

In this article, we’ll show you how to find the network security key on your router and make it even more secure to keep your devices safe.

What is a network security key?

A Network Security Key is a unique code or series of characters that connects your computer, smartphone, or any other device to a wireless network. This code helps establish a safe and secure connection between the device and the WiFi router.

The primary purpose of a Network Security Key is to protect the network from unauthorized access. Other names for the Network Security Key are the WEP Key, WPA Key, and Wireless Password.

Different types of network security keys

Among different types of network security keys, the two most commonly used security protocols are the following:

Wired equivalent privacy (WEP)
WiFi-protected access (WPA)

WPA has further two subsequent versions, which are:

WiFi-protected access 2 (WPA2)
WiFi-protected access 3 (WPA3)

Every type of network security key offers unique security features, but their core functionality is essentially the same i.e. user authorization for wireless networks.

Wired equivalent privacy (WEP)

WEP (Wired Equivalent Privacy) is the most basic security protocol invented in the early days of networking. Even though it’s not the best option, older devices might still support it.

A WEP key contains characters, including numbers (0-9) and letters (A-F). An example of a WEP key could be 1A568D7F9. As you can see, due to its static encryption code, we can easily decrypt a WEP key with simple decryption software, which makes it vulnerable to hacking. Thus, we don’t recommend you use WEP Key and put your security at risk.

WiFi-protected access (WPA)

WPA (WiFi-protected access) was developed to improve and overcome the weaknesses of WEP. It employs a temporary key, known as TKIP, to establish a connection. This protocol also provides a higher level of security by using a new 128-bit key to encrypt each data packet, making it more difficult for hackers to intercept.

Even though WPA offers more advanced features than WEP, it still has vulnerabilities and can be hacked or compromised by cyberattacks.

WiFi-protected access 2 (WPA2)

As we discussed earlier, WPA2 is the next version of WPA, and it comes with advanced AES encryption, which makes it an excellent choice for both residential and commercial use. This security standard has been around since 2006, and practically every device you use nowadays supports it.

WiFi-protected access 3 (WPA3)

WPA3 provides the most up-to-date and secure network encryption. There are two differences between WPA3 and WPA2: a more advanced encryption method (192-bit cryptographic strength) and a more secure initial key exchange mechanism.

Aside from security, WPA3 also makes it easier to connect wireless devices without a screen and still makes it possible to secure your connection even if the password for your wireless network is weak. All devices that come after 2020 support WPA3.

Note: Regardless of which security protocol you use or how strong passwords you have, they are merely the baseline of your online security. So, get PureVPN to protect your online privacy now because it uses AES 256-bit data encryption, which is much more safer than WPA3 192-bit encryption.

Why is network security necessary?

Here are some of the reasons why Network security is necessary for you:

By implementing network security measures such as using Network Security Key, VPN, etc., you can ensure the overall security of your network.
It keeps your network and data functional, reliable, and safe.
Protects against viruses, malware, and other malicious software from infecting the network and disrupting operations.
Enhances privacy and confidentiality by encrypting sensitive data transmission.
It also assures that sensitive information is only accessible to authorized individuals.

Note: Using a VPN is one of the best practices to add a layer of network security to protect your sensitive data and enhance privacy.

Step-by-step guide on how to find the network security key on the router

A network security key is usually visible on a router’s exterior. So, to find the network security key, check the back or bottom of your router for a sticker that includes the key, or refer to the manual or packaging box provided by the manufacturer or ISP.

On the router, look for terms such as:

WEP key
WPA key
Password
Security key
Wireless password

The default WiFi password could put your network and devices at risk if you do not change it, so we strongly recommend you change the security key with a strong password you can remember.

How to change your network security key (WiFi password)

Here are steps you can follow to change your network security key (WiFi password);

To get started, you’ll need to find your router’s IP address which you can see in the manual that came with the device.
Alternatively, if you are already connected to the network, you can find the IP address on your computer. For Windows operating systems, right-click the “Start” button and select “Run” now, type “cmd,” then type the command “ipconfig” and press enter. On a Mac, press the option key and right-click the WiFi symbol in the top-right corner of the screen to find the router’s IP address.
After you have the IP address, open a web browser and type it into the address bar to access the router’s settings page.
Now, log in using the default credentials in the manual or provided by your ISP.
After logging in, find a section labeled “wireless,” “wireless settings,” or “wireless security.”
Select the WPA2 because it offers the best encryption.
Now, change your password or network security key accordingly.
Lastly, Save the changes and reboot your router.

Now you can use your updated password to reconnect with your WiFi connection.

Network security essential mismatch error: What is it and how to fix it

A network security fundamental mismatch error occurs when you try to connect the device to a wireless network, but you accidentally enter the wrong security key (password).

We all make mistakes when typing passwords. However, if you are sure that you’ve entered the correct password and are still getting the network security critical mismatch error, follow the steps below to fix this issue immediately.

Recheck the password: The first thing is to recheck the password. We often set the password as case-sensitive, so make sure you use the correct capitalization; check the “Caps Lock.”
Restart your router and device: If the issue remains the same, try restarting it by turning it off and then on again to see if it resolves the problem.
Update the router’s firmware: Make sure that the router’s firmware is up to date. If not, update the firmware to resolve any compatibility issues with the device.

Note: If none of the above solutions work, it may be a problem with the router or device. Contact the manufacturer for further assistance.
