It’s easy to connect to your network – most of the time. However, there may come a day when you turn on your laptop, try to go online, and get hit with an error message. A common and very easy to resolve message that you can receive is “Network Security Key Mismatch”. However, if you have never seen this error before, you can be clear about what it means and how to correct it. Fortunately, this is a simple bug that does not require much technical expertise.
What Does Network Security Key Mismatch Mean?
When you connect to your network, this message may appear in a pop-up window where you enter your password. In simple terms, this message simply means that the character string you enter as the network password does not match. If your password is configured, it must be entered exactly as it was when it was created. This includes adding letters, numbers and symbols, and the password is case sensitive. If a password is entered that does not match the password stored by the network, this error occurs.
How to troubleshoot network security key errors

- Open the Network and Sharing Center.
- In the left pane, click Manage Wireless Networks.
- In the list of networks, right-click on your wireless network and click Properties.
- Click on the Security tab and check the settings.
Make sure your WiFi version is supported.

Some routers issue the network security key anomaly message even if the key is correct. You do this because the router currently does not accept signals of your WiFi type and therefore cannot receive the signal from your device containing the key.
There are different types of WiFi – 802.11B, 802.11G, 802.11G, 802.11G, 802.11G, 802.11N, etc. The features of each type are not relevant to solving the problem; you just need to know that if you use the wrong WiFi type, you will not connect.
To change the types of WiFi supported by your router, connect to the router and search for this setting. Each router has a different control panel, so we can’t tell you exactly where it will be, but it is usually relatively easy to find. If you can’t find the option, try calling the helpdesk of the company that manufactures your router, such as Linksys or Netgear.
Make sure your network drivers are up to date.
Depending on the users, your drivers can sometimes cause problems with the network security key. If you cannot connect to your wireless network, make sure that the drivers for your network adapter are up to date.
There are several ways to update your drivers, but the best way is to visit the website of the manufacturer of your network adapter and download the latest drivers for your model. To do this, you must use an Ethernet connection or download the driver to another device and then transfer it to your PC.
Disable your third-party antivirus program.
Third-party antivirus programs are a common cause of this problem. They can often interfere with connection protocols, and we strongly recommend that you disable them for a period of time to see if the problem persists. If the problem persists, you may need to uninstall it and choose another security option.
Conclusion
If you can connect the router using a cable, but still have difficulty correcting the network security key inadequacy problem after trying the above corrections, the router itself may have a problem. Make sure you notice all the flashing error lights, and if everything else fails, call the hotline and wait for someone to help you.
