“Weak Security” Wifi after iOS 14 update

WPA2 Personal is still a problem. You need WPA2 (AES) or WPA3

I had to connect to my router and change my authentication mode

Did you reboot your router and extenders and forget the network on your iPhone and set it up again?

On Xfinity we you dont jave have access to WPA2 AES. Its already chosen for you and you cannot change it unless its on the Xfi app. On the you can choose WPA2 or open. Whos choosing open idk? But yea the router is set to WPA2 AES and still weak security.

the message/warning was added in iOS 14. It's just telling you that your wifi is not very secure.

Your wifi was not secure before you installed iOS 14, there is just a message now informing you of it to encourage users to use more secure settings

Many people have stated already that their router is already configured to the correct protocols. Many have failed to address that if you have a range extender and/or repeater that uses old protocols, you will get the warning as well.

There are two totally unrelated issues. Weak Security has absolutely nothing to do with your data usage. All it means is that an outsider can hack your router. You have fixed that. But even with weak security your router should work fine. If it doesn’t that’s a different issue.

If your phone is not using Wi-Fi when you think you are connected to your network that is completely separate. As a first step go to Settings/Cellular and scroll to the bottom, and turn off Wi-Fi assist. When on, if your Wi-Fi connection is weak it will automatically switch to cellular.

The next possibility is the phone disconnects from Wi-Fi when it sleeps, to save battery energy. So if you have background processes running on your phone (such as streaming) it will use cellular data. The only solution for this is to keep the phone plugged in when streaming music.

As far as the Vigin hub 3.0 is concerned

if you go to the router setting type in

192.168.0.1 in search bar of internet address this takes you to router and underneath router is the hubs password enter it choose wireless signal. Make sure both

frequency's are enabled 2.4ghz and 5ghz

are enabled save changes

On iphone if it has still the same message forget the network on phone and reconnect this message should now be gone

The risk is that someone within range of your network will be able to use it and possibly view data going though the network. As long as you have remote management disabled there is no other risk.

You do not want it set to WPA3 if you have devices on your network more than a few years old. However, WPA2(AES) by itself is secure, and, if your router supports it, WPA2(AES)/WPA3 will allow devices that support WPA2 or WPA3 to work. As WPA2 was first published 15 years ago it is unlikely that you have any devices that are not compatible with it.

You log into the router’s control center with a web browser. You need to check the manual or the manufacturer’s website if you don’t know how to do that because all routers are different.

Have you updated to 14.0.1, which specifically lists on the update description that it fixes Wi-Fi issues for some phones? Or to 14.1?

Your router (not modem) is probably WPA/WPA2(AES), which is not the same as pure WPA2(AES).

You probably learned that it is wpa2-aes capability, not set as that. See how I fixed this on my centurylink router in a reply above.

Not a bug.

If you are seeing the message, something on the network, whether the router or one of the mesh extenders, is still allowing WPA/TKIP or WEP connections.

Time to eat crow. I did have one extender tucked away in a corner that was misconfigured. So, you were right.
