How to Fix Weak Security Wi-Fi Warning on iPhone

In this era of ultra-technology, many of us rely on a Wi-Fi network to stay connected with the world. As an iPhone user, you may sometime notice the "Weak Security" warning while trying to connect to a Wi-Fi network.

Usually, it occurs when the Wi-Fi connection you are trying to connect is not secure enough. In this guide, we will let you know what does weak Wi-Fi security mean on iPhone and how to fix the problem. Keep reading.

1. What Is Wi-Fi Security?

Wi-Fi networks arrive with different security standards to prevent unethical access and secure the user's privacy. The security standards are regularly updated to deal with the evolving threats and keep the network secured.

The Wi-Fi security standards include WEP, WPA/WPA2, and WPA3. The WEP is the oldest standard, and the WPA3 is the latest and most secured one.

Types of Wi-Fi Encryption Standards

Now let's know a bit more about the 4 different types of Wi-Fi encryption standards:

  • WEP: WEP is the first Wi-Fi encryption standard that stands for Wired Equivalent Privacy. It came to action in 1997 to assure the confidentiality of the data transfer in wireless networks. As of now, the standard is outdated and not strong enough to deal with Wi-Fi threats.

  • WPA: The WPA standard replaced the WEP in 2003. It stands for Wi-Fi Protected Access, and it is more capable than the WEP, although it too is outdated now.

  • WPA2: The WPA2 standard was released in 2004, and it was an updated version of WPA. It was based on the IEEE 802.11i standard and arrived with better encryption and authentication. WPA2 is a widely used Wi-Fi protocol currently.

  • WPA3: The WPA3 is an upgraded version of WPA2, released in 2018. It comes with better capability to deal with the latest Wi-Fi vulnerabilities like KRACK, brute-force, etc. It is the most secure and advanced protocol available currently.

2. Why Does iPhone WiFi Say Weak Security?

Simply put, your iPhone will show the Weak Security warning when you are trying to connect to a Wi-Fi network that arrives with older Wi-Fi encryption standards like WPA and WPA2 (TKIP). Apple started showing this message from the iOS 14 as a feature to assist you with personal privacy and security.

You can check if a Wi-Fi network is weak or not by going to Settings > Wi-Fi. You will see the "Weak Security" notice below the Wi-Fi now.
