Wi-Fi “Weak Security” on iPhone. How to Fix in iOS 14?

Many iPhone and iPad owners who have recently updated their devices to iOS 14 and iPadOS 14 faced the “Weak Security” warning in their Wi-Fi settings. Here is how to fix the problem.

What Does This Mean?

The ‘Weak Security” warning in your iPhone’s Wi-Fi settings means that your Wi-Fi network is using vulnerable technologies. It either uses the WPA as authentication method or TKIP as the encryption or both at the same time.

If you go to the network properties, your iPhone and iPad should be telling you “WPA is not considered secure” or “TKIP is not considered secure”.

And below you will find the recommendation “If this is your Wi-Fi network, configure the router to use WPA2 (AES) or WPA3 security type”

WPA (TKIP) is not considered secure
WPA / TKIP is not considered secure (iOS 14)

That is actually true. WPA (first generation) and TKIP are outdated security protocol and encryption respectively.

Сlarification

On some routers you need to first select WPA/WPA2 and then specify the WPA2 version below. It is a little bit confusing. Here is how it looks on TP-Link routers:

select WPA2 version TP-Link
Select the proper security version

After modified these settings and rebooted your router (if prompted), reconnect to this hotspot from your iPhone (iPad). The warning should be gone.

Conclusion

iOS 14 and iPadOS 14 are designed to alert you in case if you are connected to a Wi-Fi network with weak security.

That is very important to avoid such hotspots because your device may got hacked and your sensitive data can be eventually stolen.

We advise to switch your router to WPA2 with AES. In case if the router doesn’t belong to you, we advise to immediately disconnect from such network and forget it.
