My iPhone Says “Weak Security!” Here’s The Real Fix.

You were connecting your iPhone to Wi-Fi when you noticed a new message under the name of your Wi-Fi network. It says Weak Security, but you’re not sure why. In this article, I’ll explain why your iPhone says “Weak Security” and show you how to fix the problem.

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 This is an outdated router configuration, but one most people will be able to quickly update.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 or 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.

A Brief Word Of Warning

Unfortunately, some older devices aren’t compatible with newer security protocols. Some routers do support backward compatibility, and this is sometimes called “transitional mode” in your router’s settings.

If some of your older devices stop connecting to Wi-Fi, check for a “transitional” or “mixed” mode in your router’s settings. This may allow your older devices to connect to your Wi-Fi network using WPA2 encryption, while also allowing newer, compatible devices to connect using WPA3 encryption.

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.

I followed your instructions and changed from a “WPA2/WPA Mixed Personal” setting to just WPA2, However, our iphones still indicate “Weak Security”. Do you have any additional advice? Same as Patty’s comment. Replies highly welcome!

Thank you for the article. But when I type, it takes me to a page and make me download the Linksys app. Which I did and then in the app it asked me to add the wifi to the account. I said ok and it asks me to add the password of my wifi router. I enter it and it gives wrong password error. Nothing I can do and the password is right bcos I connected my devices to the wifi using the password. I don’t know how to get to the security setting to change wpa2 to 3.… Read more »

I appreciate the clear description of what to do. After doing this none of my legacy devices (vacuum robot, thermostats, sprinkler system) were able to connect. Is WPA2 not backwards compatible? Thanks

Excellent!! Thoughtfully written for us not so experienced users. Apple told me to contact ip but they were of no help and they told me to contact Apple.
I skipped all of that mess and went to Google, up popped your article and voila!! It worked 😎 Thank you! Well done!
