How to Fix Wi-Fi Weak Security iPhone Error?

Upon connecting to a Wi-Fi network, your iPhone or iPad may show you a somewhat disturbing error message: “Wi-Fi Weak Security.” That is not something you can ignore. Poor security in your home or other networks potentially exposes you to attackers and bad actors who can steal your sensitive data or infect devices within the network.

In most cases, the “Weak Security” message means the network uses an outdated encryption protocol, such as WEP or WPA. Old protocols are less secure, and they are easier to crack. You do not want to connect to a Wi-Fi network that uses old encryption protocols, not to mention use such a network for banking or sending sensitive data.

What to Do if iPhone Wi-Fi Says Weak Security?

If the “Wi-Fi Weak Security” error pops on your iPhone’s screen when you are not at home, the best thing you can do is disconnect from the network right away (if possible, of course). Also, you can forget the network to ensure your Apple devices cannot connect to it automatically.

  1. Open the Settings app and go to Wi-Fi.
