“Weak Security” Wifi after iOS 14 update

Since updating to the newest iOS 14, my WiFi connection has an alert of “Weak Security”. I’ve called both my internet/service provider and both show on their end the system is registering correctly. Upon reading more, apparently the newest iOS creates a new MAC address that may not be recognized on the modem you use, causing a “Weak Security” notice? My wifi connection on my phone is slower than if I were disconnected from it.


All my other devices work on my wifi.


Any suggestions on how to get rid of this?

I have the same question how can I fix 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. 


See this Apple support article for how to configure it correctly—>Recommended settings for Wi-Fi routers and access points - Apple Support, specifically the section headed Security. And don't forget to configure your range extenders (if any) also! After changing the router settings be sure to forget the network on your phone, then reconnect.

Unfortunately one of my iPhones was set to automatic updates and has install iOS 14 and now I have this problem. Vodafone router that supports WPA2. Vodafone support tell me this is sufficient and that others users have solve the problem by changing to a password that includes uppercase, lowercase, a symbol and some numbers. My password already includes all of that but it still doesn't work. Three other family members with a total of some 12 wifi devices use the network, so I don't really want to change the password and then find out that the iOS 14 device still won't connect.

Weak security is a warning. It doesn’t interfere with how Wi-Fi works. If you phone doesn’t connect that has nothing to do with the warning. You are perfectly free to use your current WiFi settings, now knowing that your router can be hacked. It also has nothing to do with you WiFi password.


you need to troubleshoot the WiFi connectivity problem separately, which is beyond the scope of this thread.

It must be Vodafone that are misguided then. The warning message appears on my iPhone with a "!" symbol through the WiFi symbol, "No Internet Connection" in orange, and the star / wheel that just keeps going round.


The IP address is coming up as 169.254.231.155 and mask as 255.255.0.0. My network is the customary 192.168.1.nnn and 255.255.255.0 I've not got MAC address filtering enabled.


I've been using tcp/ip since about the time Tim Berners-Lee wrote the rfc on domain name resolution.


Are you suggesting that I need to get a replacement router from Vodafone to solve this problem? The one I have has WPA2 which Vodafone support are telling me includes the -PSK + AES functionality.
