“Weak Security” Wifi after iOS 14 update

It will never be “corrected” by Apple because it is working as designed. iOS 14 checks the security level of your router, and warns you if it is not up to current security standards. You are free to continue using your hackable router for as long as you want to; the fact that you have been warned will not prevent you from using your insecure router. But your router has ALWAYS had weak security; you just didn’t know about it until now.

IF you want to fix it change the encryption setting to WPA2(AES), or WPA2-PSK(AES), or WPA2-Personal. If your router is more than 5 years old and doesn’t have any of these settings either live with your hackable router or replace it.

This is NOT an iPhone problem; it is a problem with your router settings.

A "Weak Security" notification means that your Wi-Fi router is not configured correctly. There is a new feature in iOS 14 that checks and displays a message if your router is not using the most up-to-date security. Note that your router has always had weak security, you just didn’t know about it until now.

There are various authentication and encryption protocols that have been used over the various generations of WiFi. Currently WPA2 with AES or WPA3 are the most secure. If you are using the older WPA, (or heaven forbid, WEP) you will get this warning on IOS 14. The other cause is most likely that the older TKIP encryption protocol is enabled on your wireless. Most routers will allow both AES and TKIP to be used. If you have the ability to disable TKIP (allow AES only) the warning should go away.

The issue is not with your phone, it's with your wireless router. In your wireless router settings make sure the security type is set to WPA2 and the encryption is set to AES. Most likely you either have the original WPA enabled, or you are using TKIP encryption which is old and deprecated. Some routers allow you to allow both AES and TKIP, if possible disable TKIP.

It appears that most people who are experiencing this have their encryption set to TKIP or have both AES and TKIP enabled, which is allowed on some WiFi routers and APs.

As long as TKIP is enabled, even as an option, you will see "Weak Security" on your iOS device running v14 or later.

Your settings must be WPA2 with AES (only) or WPA3. You need to disallow TKIP encryption.

I guess you didn’t read the answer, but here it is again, with emphasis added in response to your post:

This is NOT an iPhone problem; it is a problem with your router settings. So your sister’s router is configured correctly, but yours is not.

Note also that weak security does not interfere with using Wi-Fi, it is just a warning. Your Wi-Fi should still work normally, and, if it doesn’t, it is not because of the weak security message.

I have updated my iPhone 11 promax and I can get no phone calls or Texts in or out and it even states unable to call 911 from this phone and it keeps telling me I have a week security? I need to get this fixed ASAP as I can’t care of a child I’m part of life support and cannot afford this kind of stuff.. I have a VPN on my phone set up to McAfee which is metro security please someone give me a solution for this thank you

The issues with texts and calls are not related to the weak-security informational message. There’s something else happening with the local network or the iPhone or the ISP connection unrelated to the Wi-Fi security. The VPN client is a good candidate culprit here as mentioned above, as those VPN clients can to be hazardous to privacy and to security and to connectivity.

Again... The Wi-Fi network connection here can and will and does continue to operate with weak security.

Your Wi-Fi router is using WEP, WPA, or WPA2 TKIP security, and Apple is referencing the weaknesses known among these three Wi-Fi security configurations. To clear the informational message—again, this informational message does not prevent usage of networks with weak security—the router needs to be reconfigured to use WPA2 AES, WPA2/WPA3 transitional, or WPA3 security.

Whether or how that reconfiguration can happen depends on your specific router. You’ll need to identify the vendor and model, then locate the manual, and do a little reading.

If this Wi-Fi router was provided directly from your ISP some years ago, contact your ISP as this won’t bemthe first time they’ve heard about this diagnostic.

Whether the router can be reconfigured or replaced varies.

Here is more info on this from Apple: Recommended settings for Wi-Fi routers and access points - Apple Support

I’d also remove the VPN client add-on and the add-on anti-malware, as well.

A "Weak Security" notification means that your Wi-Fi router is not configured correctly. There is a new feature in iOS 14 and Mac Big Sur that checks and displays a message if your router is not using the most up-to-date security settings.

After you change the router settings you should Forget the network in your phone settings and reconnect.

Note also that weak security does not interfere with using Wi-Fi, it is just a warning. Your Wi-Fi should still work normally, and, if it doesn’t, it is not because of the weak security message.

Why do I see “weak security” in my wifi on both my iPhone and iPad?

Because your router is not configured to use strong security. It has always had weak security, but you didn’t know it until iOS 14 told you about it. You need to configure the router to use WPA2(AES) or WPA3, rather than WPA(TKIP) or whatever else it might be set to. If it’s a very old router you may need to replace it.

It would have been SO helpful if you had bothered to read any of the posts in the thread that you posted to, especially the one right above yours, but to save you the trouble of scrolling up here is the answer again:

If it says Weak Security, that means that your router is not configured correctly. iOS 14 checks and displays that message if your router is not using the most up-to-date security. Note that your router has always had weak security, you just didn’t know about it until now.
