Why does Windows 10 say your Wi-Fi network is not secure?

Windows 10 now warns you that a Wi-Fi network is "not safe" if it uses "an older security standard that expires". Windows 10 warns you about WEP and TKIP. This is the meaning of this message – and how it can be fixed.

As of the May 201

9 update, Windows may display a message that your network is not secure, even if you know you are using a password. When this message appears, you are likely to use either Wired Equivalent Privacy (WEP) encryption or Temporal Key Integrity Protocol (TKIP) encryption. These encryptions are not safe to use and you should upgrade to a newer protocol or replace your router as soon as possible.

Why Windows 10 Alerts You

You probably know that you should password protect your Wi-Fi network. Whether you want to keep your neighbors out or remove bad cast members from your system, securing your wireless network is the best way to do it. However, adding a password to your wireless router will not only keep people out of your network. The security log encrypts your data to prevent other people in the area from listening to your activity.

There are several ways to encrypt your wireless network: WEP, WPA, and WPA2. WPA3 is also on the way. WEP is the oldest and least secure at this time. Look at this way; The Wi-Fi Alliance ratified WEP in 1999. This is older than Windows XP, YouTube, and the original iPod. WPA-TKIP was already supported in 2002.

For this reason, Windows warns you about these networks with the following warning:

[Network Name] is not secure

This wireless network uses an older security standard that expires. It is recommended to connect to another network.

Why WEP and TKIP are dangerous

WEP and WPA-TKIP are still pretty common. We've found that WEP is still in use on a relative's ISP router. We did not have to change anything or activate WEP. They already used it. WEP is a notoriously cumbersome encryption option. It was like that from the start and never got better.

When the encryption protocol was first released, most devices restricted WEP to 64-bit encryption due to US regulations. This has improved, but as you can see above the router, we were still trying to use 64-bit encryption. In comparison, WPA uses 256-bit encryption. Worse, over time, several bugs were found in the log, making encryption easier to crack. In 2005, the FBI demonstrated its ability to crack WEP encryption in minutes.

The Wi-Fi alliance wanted to replace WEP with WPA-TKIP, but the newer protocol unfortunately uses many of the same mechanisms. Because of this choice, the two protocols also share many of the same vulnerabilities. One way to break one usually works just as well with the other. Therefore, the use of TKIP is not more secure than WEP.

In this knowledge, Microsoft would like to warn you if you are using WEP or TKIP so that you can fix the problem. Doing so now is especially important as Microsoft plans to phase out or "outdated" support for the logs. In this case, the latest versions of Windows 10 can not connect to these networks.

How to Fix This Error in Your WLAN.

 Security settings of the router with different encryption options.

If this message appears when connecting to a public Wi-Fi network, this is not possible. Repair it. The owner of the router must fix the problem. For this reason, Windows recommends connecting to a different network.

If this message appears when you connect to your Wi-Fi network, you should enable stronger Wi-Fi encryption. If your router is relatively new, it has other options like WPA2 with AES, and you should switch to them. Unfortunately, the administration page of each router is different. Therefore, it is difficult to give instructions for this change. You may want to look up instructions for configuring your specific router model or refer to its manual.

You want to get the IP address of your router and enter it into your browser. Then search for your Wi-Fi security settings. Watch out for sections on WEP or passwords. If you're wondering what to choose, our recommendation is to first select WPA2 + AES when it's available. If this is not possible, select WPA + AES.

The wording in your router's dialog box may differ slightly, but all of these letters should be present. For example, WPA2 + AES might look like "WPA2-PSK (AES)". You must update the password on all your devices (even if you use the same password as before) after making the change.

Update Your Router If You Can not Improve Encryption

If you do not see better options than WEP or TKIP, you should replace your router as soon as possible. If you use a router provided by an Internet service provider, you can contact him to see if he offers a newer model.

A better option, however, is to buy a router and return the old router to your ISP. You may be charged a monthly fee, and depending on how long you have already had the router you can pay several times.

You do not have to spend a lot of money on a router. If you have a mid-sized home with a median number (20 or fewer) of Wi-Fi devices, the TP-Link AC1750 is relatively cheap and easy to set up with $ 56.99. You can even control it via an app if you want.

Regardless of how you stop using WEP or TKIP, the sooner you take care of the problem, the better. Not only are you in a vulnerable position because you rely on an outdated security protocol, but your Windows devices will eventually end the connection completely. Avoid this scenario better and protect your network now.
