It tells you what to do. Your router is set to use WPA and WPA2. WEP (the oldest Wi-Fi security) was broken long ago. WPA replaced it and that too is no longer secure. iOS is letting you know your router is broadcasting an easily hacked wireless security protocol, and you should turn WPA (not WPA2) off.


From your Mac or Windows computer, go into your router's web setting pages. You should be able to do this from your iPhone, too, as long as you're within Wi-Fi range of your router. Typically, you put 192.168.0.1 into the URL search field. The router should prompt you for an admin name and password. If you don't know what those are, almost all newer routers have that info on a sticker, which is on the router itself.


Once in the settings pages, go to the wireless settings. You should be able to find a drop down menu for the security options. Change it to use WPA2 only, or WPA2/WPA3 if you have that option. Save the settings (the router may tell you it has to be restarted).


One possible downside. If you have much older devices that connect to the router that don't understand any security protocol newer than WPA, they'll no longer be able to talk to the router.

IT IS NOT AN IOS PROBLEM OR A BUG IN iOS. PERIOD. It is a misconfigured router. And most people have fixed it by changing the settings in their router to the correct settings. It has nothing to do with what your router model is, unless it is too old to support WPA2(AES) or WPA3. If you get the message “weak security" your router is not configured for maximum security. Your router has ALWAYS had weak security; you just didn’t know it until iOS 14 told you about it.


And it is only a warning. It will not affect your ability to use the router with your iPhone or iPad. It warns you that bad actors can hack into your router. If it’s OK with you that strangers can invade your Wi-Fi network then just ignore the warning.

The risk if your router doesn’t have strong security is that someone can use your network, and can potentially monitor traffic on it that isn’t encrypted end-to-end. Further, if your router has remote management enabled they can install malware on the router and use it hack other people’s networks, launch denial-of-service attacks against other sites and monitor any home management devices you may have (security cameras, Alexa, Google Home, etc). If you live in an urban environment this is a greater risk than a rural area, because any hacker must be close to you to hack the router.


What you can do to mitigate the risk is to reboot your router frequently, and, if you can view the connected devices, make sure you recognize all of them.


Why don’t you have an option to change the security, setting, however?

I had the same problem. Apple recommends changing the security settings to WPA/WPA2 & AES. I logged on to my modem/router to check my settings and my security was ALREADY on WPA/WPA2 & AES which was the setting that Apple recommended here: https://support.apple.com/en-us/HT202068 to get rid of this “weak security” notification. THE RESOLUTION to this problem: Simply change the name of you router (instead of using the name it came with for example, linksys or netgear) by logging into your router settings (refer to your router’s user manual). After I changed the name of my router the notification went away.

I updated my router under the guidance of my ISP. The 'weak security' message disappeared from my iPhone but still appears on my Mac. I have been assured by my ISP that my wifi is up-to-date and secure; and since the alert has disappeared from my iPhone, I have assumed that my Mac is giving a false message. No other wifi user in the house is getting a security alert and I am not getting one on my old Mac.
