Why Your iPhone Says Weak Security

An iPhone says Weak Security when the Wi-Fi network its connected to is set to WPA or WPA2 (TKIP). This is an outdated router configuration, but one most people will be able to quickly update.

Apple began displaying a “Weak Security” message with iOS 14. It was one of many new features designed to help you protect your personal privacy and increase security on your iPhone.

You can check if your Wi-Fi network has weak security by opening Settings and tapping Wi-Fi. Look for the words “Weak Security” below the name of your Wi-Fi network.

How To Make Your Wi-Fi Network More Secure

Updating the security settings on your router will usually make the Weak Security message on your iPhone go away. If you’re on a public Wi-Fi network, there’s not much you can do, since you can’t control the router’s settings.

However, if your home Wi-Fi network says Weak Security, you can change your router’s settings. This may sound intimidating, but you don’t need any technical expertise to fix the problem on your iPhone.

First, access your router’s settings by typing 192.168.0.1 or 192.168.1.1 into a web browser. Most routers use one of these two addresses.

If neither work, head to Settings -> Wi-Fi and tap on the Information button next to your Wi-Fi network. Scroll down to Router and type the series of numbers into your web browser.

Once you’ve typed in the correct address for your wireless router, type in the admin username and password. A lot of the time, the username is admin and the password is password. If you need it, the login information is also listed on a sticker on your wireless router.

Once you’ve logged in, find your router’s security settings. This will look different depending on your router, so click around and keep an eye out for the word Security or Encryption.

Once you’ve found the security settings, set your Wi-Fi network to WPA2 (AES) or WPA3 (AES). There should be a Save or Apply button that will confirm the changes.

It’s okay if you don’t see a WPA3 option, as most people don’t have a Wi-Fi router that supports it. Make sure to update the Security settings for your 2.4 GHz and 5GHz network, if you have both.

Now I Can’t Connect To My Wi-Fi Network!

When you connect your iPhone to a Wi-Fi network for the first time, it saves information about how to connect to that network. If something about that process changes, like the security settings of your Wi-Fi network, your iPhone might not connect to the Wi-Fi network.

The way to fix this is to forget the network on your iPhone and set it up like new. Open Settings and tap Wi-Fi. Then, tap the information button (look for the blue i) next to your Wi-Fi network. Finally, tap Forget This Network at the top of the screen.

Once the network has been forgotten, go back to Settings -> Wi-Fi and tap on your Wi-Fi network under Networks. Enter the Wi-Fi password to reconnect to your Wi-Fi network.
