What is network security key?

If you don’t know what is network security key, the security key is nothing but the technical term that is usually attached to the routers, switches, and modems. For every network SSID or username, there is a unique security key called a WPA key or WPA2 key. This key is a combination of alphanumeric characters.

While the above terms are used in association with routers and systems, when the network settings are accessed from an android phone, the security key will be mentioned as the password. Thus both the interchangeable terminologies are used depending on the device make, device type, and network environment that it carries.

Say you decide to stay at your friend’s place for a week or so. To gain access to the wireless network of the place(Wi-Fi being so invariably necessary in our daily life,), you need the security key or the password. A password in the form of biometric data or digital signature is used to provide authorization and access to the wifi.

Router

Each router has a preset network security key. This key is usually auto-generated and difficult to remember but it can be easily changed on the settings page of the device. 

Why is the network security key important?

The network security key prevents intruders and protects your network. Without the security key, nobody can connect to the wireless network. If the network security key is strong enough then your network remains safe. So, having a really strong wifi password is important.

Different Types of network security keys

There are different types of network security keys that can be set to keep your network safe. 

WEP and WPA/WPA2 are the most commonly used types of network security keys. These passcodes or passphrases allow devices on a network to exchange encrypted messages while blocking the same from being easily decoded and read by intruders.

Difference Between WEP and WPA2

WEP (Wired Equivalent Privacy)

The WEP security key is comparatively a primitive one that uses a 40-bit key for encrypting the exchanged data. It is a sequence of characters that can range from numbers (0 to 9) and letters. The WEP key could be anything like E403AF100C. The length of a WEP key depends on the WEP version that you have on your PC, and it could be 10, 26, or 58 characters long. 

As WEP keys are easy to crack, they gradually lost the public interest and the application of WEP started getting replaced with WAP keys, on the basis of network security concerns. The current routers and network systems don’t usually support WEP anymore.

WPA/WPA2 (Wi-Fi Protected Access)

WPA and WPA2 are more widely used these days and are believed to be more secure network keys than WEP. The WPA protocol has slightly modified statistics and uses a temporary key (TKIP). This key is regenerated with every packet. So, keys encrypted with WPA2 tend to be more secure and are relatively hard to crack. A WPA2 key can be obtained from the network’s owner. 

WPA/WPA2 protocols allow the owners of the network to reset the key to suit their convenience.  WPA2 uses the AES algorithm, which is a newer, faster, and more advanced algorithm and hence is considered to be more secure as compared to WPA. WPA2 is further followed by WPA3 protocol, soon. 

WPA2 is recommended to be used in all the network modules as they tend to increase the security measures on your network with the only criteria being supportive hardware that has higher processing power,

What is a Network Security Key Mismatch? How to fix it? 

Very rarely sometimes, when you try to connect to your network, you might see an error saying Network Security Key mismatch. This mismatch issue can be triggered due to a couple of common reasons like

  • Wrong password – Well, the error could be as simple as a wrong password. There could be a silly typing error! Just recheck the password especially for case-sensitive letters.
  • Incompatible device – if by some chance you are having an older device that doesn’t support the new WPA2 network then you might encounter this error. The network would be visible but your device won’t be able to connect to it.
  • Router or access points hang – Although this is not a common cause, in some rare cases, the router or access points hang. This can be resolved by a simple restart of the router.

Perhaps, a mere restart of the wifi network or the router solves the issue.

How can I better protect my network?

Creating a strong network security key is the key to protect your network. Users with weak passwords easily fall prey to hackers. A WPA/WPA2 key that can be self-selected could be optimized and strengthened, protecting the infrastructure.

As the simplest code of action, limit down the jotting of your passwords. By writing a password you yourself open the door leaving you susceptible to hackers. 

Consider changing the network security key occasionally, to keep it more secure. Long and complex passwords, especially passphrases make secure network keys.
