"Wifi Network Isn't Secure" error on Windows

Nowadays, almost everyone knows that it is extremely important to protect network passwords. You don't want anyone to have access to your network, whether it's just your neighbor who wants free Internet or a hacker looking to steal your information. You also don't want to be "touched" by the police just because someone else uses your network for nefarious purposes, right? Passwords aren't the only protection your network needs. It also needs strong encryption so that no one can intercept the data.

WiFi encryption protocols

Since 1999, when the WiFi Alliance approved the first WiFi encryption protocol, WEP, there have been numerous updates to improve the technology. Despite all of the advances in coding, some people continue to use the outdated original protocol. There are different encryption methods used to protect WiFi networks: WEP, WPA, and WPA2. The WiFi Alliance has just started certifying new products using the new WPA3 technology. Each new protocol improves security over the previous one, making your network more secure.

However, older versions are still available and, unfortunately, are still widely used. WEP has never been a good choice for encryption, even when it was first released. The Wi-Fi Alliance abandoned this encryption method in 2004. A year later, the FBI demonstrated that hackers could easily crack WEP encryption by exploiting many of its vulnerabilities. The Wi-Fi Alliance planned to replace WEP with WPA-TKIP, but that protocol works in a very similar way to the original protocol. It has many of the same vulnerabilities. If you can crack one, you can usually crack the other too.

Windows "Wifi Isn't Secure" Warning

Windows recently added a warning that appears when you try to connect to a network protected by one of the older encryption protocols. This message is for your safety and serves as a warning, especially if you are running Windows 10, that you will soon no longer be able to connect to these less secure protocols.

This warning states: “[Network Name] isn’t secure.This Wi-Fi uses an older security standard that’s being phased out. We recommend connecting to a different network”. This message tells you that you are trying to connect to a network that is still using WEP or WPA-TKIP encryption.

How to fix the problem

If you see this message when trying to connect to your home network, you should be able to fix the problem by enabling a newer, stronger encryption method. Each router has a different method for changing security protocols, so you may have to check the manufacturer's website to find the exact location of this option. 1. Enter the router's IP address in the address bar of your browser, or if you have a Netgear router, you can type routerlogin.net to access the router. 2. Log in to the router with the username and password. If no password is set, check the router manufacturer's website for the default password. 3. Locate the web interface. It will look like the following image:

4. Choose the strongest encryption protocol available on the router.

The following is a list of encryption protocols available on most modern routers manufactured after 2006. They are arranged in descending order of security from most secure to least secure.

• Any WPA3 (this option is only available on the latest routers because it just came out).
• WPA2 + AES
• WPA + AES
• WPA + TKIP/AES
• WPA + TKIP
• WEP

If you don't see any better options than WEP or WPA + TKIP, the best way is to buy a new router. There are many affordable models available that can accommodate a mid-sized home with up to 20 WiFi devices. No matter what you do to stop using these outdated protocols, you should do so as quickly as possible. Not only were they easy to hack, but they soon became unusable on Windows devices.
